1. 기본사용법 복습

새로운 스프링 레거시 프로젝트를 만든다. 

 그리고 빌드패스에서 자바라이브러리 버전 변경, facets에서 자바 버전 1.8로 변경한다.

그리고 pom.xml에서도 버전을 변경해준다.

 

index페이지를 시작하면 바로 페이지가 넘어가도록 만들어보자.

-HomeController.java

package com.exam.web01;

import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 * Handles requests for the application home page.
 */
@Controller
public class HomeController {
	
	private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
	
	/**
	 * Simply selects the home view to render by returning its name.
	 */
	@RequestMapping(value = "index.do", method = RequestMethod.GET)
	public String home(Locale locale, Model model) {
		logger.info("Welcome home! The client locale is {}.", locale);
		
		Date date = new Date();
		DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
		
		String formattedDate = dateFormat.format(date);
		
		model.addAttribute("serverTime", formattedDate );
		
		return "home";
	}
	
}

-index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    
<%
	//페이지 자동으로 이동시키는 코드
	response.sendRedirect( "index.do" );
%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<ul>
	<li><a href="index.do">index.do</a>
</ul>
</body>
</html>

 

또한 url에 http://localhost:8080/프로젝트명/~.jsp를 사용했다면

http://localhost:8080/프로젝트명/ 만 써도 특정 jsp파일이 실행되도록 설정해보자.

-web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>

 경로까지만 입력하고 엔터치면 자동으로 index.do로 이동한다.

 

 

 

2. 파일업로드 구현하기

먼저 cos.jar를 다운받자. pom.xml에 아래코드를 추가한다.

		<!-- https://mvnrepository.com/artifact/servlets.com/cos -->
		<dependency>
		    <groupId>servlets.com</groupId>
		    <artifactId>cos</artifactId>
		    <version>05Nov2002</version>
		</dependency>

-write.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>

<form action="write_ok.do" method="post" enctype="multipart/form-data">
파일 : <input type="file" name="upload" />
<input type="submit" value="파일전송" />
</form>

</body>
</html>

-HomeController.java

package com.exam.web01;

import java.io.IOException;
import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.oreilly.servlet.MultipartRequest;
import com.oreilly.servlet.multipart.DefaultFileRenamePolicy;


@Controller
public class HomeController {
	
	@RequestMapping( value="write.do" )
	public String write() {
		System.out.println( "write() 호출" );

		return "write";
	}

	@RequestMapping( value="write_ok.do" )
	public String write_ok(HttpServletRequest request, HttpServletResponse response) {
		System.out.println( "write_ok() 호출" );
		
		String uploadPath = "C:\\Java\\spring-workspace\\SpringWebEx01\\src\\main\\webapp\\upload";
		int maxFileSize = 1024 * 1024 * 2;
		String encType = "utf-8";
		
		MultipartRequest multi = null;
		
		try {
			multi = new MultipartRequest(request, uploadPath, maxFileSize, 
					encType, new DefaultFileRenamePolicy() );
			
			System.out.println( multi.getOriginalFileName("upload") );
			System.out.println( multi.getFilesystemName("upload") );
			
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} 
		
		return "write_ok";
	}
	
}

 

만약에 파일말고 데이터를 받는다면 아래와 같이 "data"로 보내고 받아준다. 

-write.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>

<form action="write_ok.do" method="post" enctype="multipart/form-data">
데이터 : <input type="text" name="data" /><br><br>
파일 : <input type="file" name="upload" />
<input type="submit" value="파일전송" />
</form>

</body>
</html>

-HomeController.java

package com.exam.web01;

import java.io.IOException;
import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.oreilly.servlet.MultipartRequest;
import com.oreilly.servlet.multipart.DefaultFileRenamePolicy;


@Controller
public class HomeController {
	
	@RequestMapping( value="write.do" )
	public String write() {
		System.out.println( "write() 호출" );

		return "write";
	}

	@RequestMapping( value="write_ok.do" )
	public String write_ok(HttpServletRequest request, HttpServletResponse response) {
		System.out.println( "write_ok() 호출" );
		
		String uploadPath = "C:\\Java\\spring-workspace\\SpringWebEx01\\src\\main\\webapp\\upload";
		int maxFileSize = 1024 * 1024 * 2;
		String encType = "utf-8";
		
		MultipartRequest multi = null;
		
		try {
			multi = new MultipartRequest(request, uploadPath, maxFileSize, 
					encType, new DefaultFileRenamePolicy() );
			
			System.out.println( multi.getOriginalFileName("upload") );
			System.out.println( multi.getFilesystemName("upload") );
			
			//file외에 다른 것을 받을 경우 "data"란 이름을 받는다.
			System.out.println( multi.getParameter( "data" ) );
			
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} 
		
		return "write_ok";
	}
	
}

 

다른 방법으로 cos.jar외에 다른 라이브러리를 사용하는 것이다.

1. cos.jar

2. common-io / common-fileupload

 

common-io와 common-fileupload 라이브러리를 사용해보자.

아래 라이브러리 코드를 pom.xml에 붙여넣기 한다.

<!--common-io -->
<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.8.0</version>
</dependency>



<!-- common-fileupload -->
<!-- https://mvnrepository.com/artifact/commons-fileupload/commons-fileupload -->
<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.4</version>
</dependency>

 

파일의 크기 설정은 webapp/WEB-INF/spring/appServlet/servlet-context에서 한다.

1040576이 1MB이고, property의 value에 * 부호를 사용하지 못하므로 계산된 결과를 넣는다.

 

또한 common-io와 common-fileupload 라이브러리를 사용하면 업로드된 파일을 개발자가 설정한 폴더로 바로 옮기는 것이 아니라 톰캣내부 버퍼 공간에 저장했다고 옮기게 된다. 

이때 이 임시공간의 크기를 설정하는 것이 maxInMemorySize이다.

-HomeController.java

package com.exam.web01;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;

import com.oreilly.servlet.MultipartRequest;
import com.oreilly.servlet.multipart.DefaultFileRenamePolicy;


@Controller
public class HomeController {
	
	@RequestMapping( value="write.do" )
	public String write() {
		System.out.println( "write() 호출" );

		return "write";
	}

	@RequestMapping( value="write_ok1.do" )
	public String write_ok1(HttpServletRequest request, HttpServletResponse response) {
		System.out.println( "write_ok() 호출" );
		
		String uploadPath = "C:\\Java\\spring-workspace\\SpringWebEx01\\src\\main\\webapp\\upload";
		int maxFileSize = 1024 * 1024 * 2;
		String encType = "utf-8";
		
		MultipartRequest multi = null;
		
		try {
			multi = new MultipartRequest(request, uploadPath, maxFileSize, 
					encType, new DefaultFileRenamePolicy() );
			
			System.out.println( multi.getOriginalFileName("upload") );
			System.out.println( multi.getFilesystemName("upload") );
			
			//file외에 다른 것을 받을 경우 "data"란 이름을 받는다.
			System.out.println( multi.getParameter( "data" ) );
			
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} 
		
		return "write_ok";
	}
	
	@RequestMapping( value="write_ok2.do" )
	public String write_ok2( @RequestParam("upload") MultipartFile multipartFile ) {
		System.out.println( "업로드 이름 : " + multipartFile.getName() );
		System.out.println( "파일 이름 : " + multipartFile.getOriginalFilename() );
		System.out.println( "파일 사이즈 : " + multipartFile.getSize() );
		
		FileOutputStream fos = null;

		try {
			fos = new FileOutputStream( uploadPath + "\\" + multipartFile.getOriginalFilename() );
			fos.write( multipartFile.getBytes() );
			
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {
			if( fos != null ) try { fos.close(); } catch( IOException e ) {}
		}
		
		return "write_ok";
	}
	
}

 

파일이름이 중복되면 오버라이팅된다. 따라서 이를 위해 파일이름변경이 필요하다 DefaultRenamePolicy알고리즘을 넣어야한다. 이 알고리즘은 예를 들어 파일업로드 시간이 다른데 파일 이름이 같은경우 나중에 올린 파일이름 뒤에 숫자를 붙여주거나 하는 식이다.

 

 

3. view페이지를 json형식으로 출력하기

맨 위와 같은 방법으로 새로운 프로젝트를 만든다.

simple-json 라이브러리를 복사해서 pom.xml에 붙여넣는다.

<!-- https://mvnrepository.com/artifact/com.googlecode.json-simple/json-simple -->
<dependency>
    <groupId>com.googlecode.json-simple</groupId>
    <artifactId>json-simple</artifactId>
    <version>1.1.1</version>
</dependency>

-json1.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8" trimDirectiveWhitespaces="true" %>
<%@ page import="org.json.simple.JSONArray" %>
<%@ page import="org.json.simple.JSONObject" %>

<%
	JSONArray jsonArray = new JSONArray();

	JSONObject obj1 = new JSONObject();
	obj1.put( "name", "name1" );
	obj1.put( "publischer", "publischer1" );
	obj1.put( "author", "author1" );
	obj1.put( "price", "price1" );
	
	JSONObject obj2 = new JSONObject();
	obj2.put( "name", "name2" );
	obj2.put( "publischer", "publischer2" );
	obj2.put( "author", "author2" );
	obj2.put( "price", "price2" );
	
	jsonArray.add( obj1 );
	jsonArray.add( obj2 );
	
	out.println( jsonArray );
%>

-servlet-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:beans="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd
		http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

	<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
	
	<!-- Enables the Spring MVC @Controller programming model -->
	<annotation-driven />

	<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
	<resources mapping="/resources/**" location="/resources/" />

	<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
	<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<beans:property name="prefix" value="/WEB-INF/views/" />
		<beans:property name="suffix" value=".jsp" />
	</beans:bean>
	
	<context:component-scan base-package="com.exam.web01" />
	
	
	
</beans:beans>

위에 json1.jsp에서 json데이터를 만들어서 출력해도되고 아래처럼 Controller에서 만들어서 출력할 수 있다.

-HomeController.java

package com.exam.web01;

import java.util.HashMap;
import java.util.Locale;
import java.util.Map;

import org.json.simple.JSONValue;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HomeController {

	@RequestMapping(value = "/json1.do" )
	public String json1(Locale locale, Model model) {
		
		return "json1";
	}
	
	
	@RequestMapping(value = "/json2.do" )
	@ResponseBody
	public String json2(Locale locale, Model model) {
		Map<String, String> map = new HashMap<String, String>();
		
		map.put( "name", "name1" );
		map.put( "publischer", "publischer1" );
		map.put( "author", "author1" );
		map.put( "price", "price1" );
		
		return JSONValue.toJSONString( map );
	}
	
}

-index.jsp(실행jsp)

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<ul>
	<li><a href="json1.do">json1.do</a>
	<li><a href="json2.do">json2.do</a>
</ul>
</body>
</html>

 

 또한 리스트형태로 json을 만들어서 출력할 수 있다.

-HomeController.java

package com.exam.web01;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Locale;
import java.util.Map;

import org.json.simple.JSONValue;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HomeController {

	@RequestMapping(value = "/json1.do" )
	public String json1(Locale locale, Model model) {
		
		return "json1";
	}
	
	
	@RequestMapping(value = "/json2.do" )
	@ResponseBody
	public String json2(Locale locale, Model model) {
		List<Map> lists = new ArrayList<Map>();
		
		Map<String, String> map1 = new HashMap<String, String>();
		map1.put( "name", "name1" );
		map1.put( "publischer", "publischer1" );
		map1.put( "author", "author1" );
		map1.put( "price", "price1" );
		
		Map<String, String> map2 = new HashMap<String, String>();
		map2.put( "name", "name2" );
		map2.put( "publischer", "publischer2" );
		map2.put( "author", "author2" );
		map2.put( "price", "price2" );
		
		lists.add( map1 );
		lists.add( map2 );
		
		return JSONValue.toJSONString( lists );
	}
	
}

 -HomeController.java

여기서 autowired는 주입하려는 객체의 빈을 자동으로 찾아줘서 주입시켜주는 어노테이션 기능이다.

찾는 순서는 먼저 같은 타입 -> bean의 이름 순으로 찾는다.

package com.exam.web03;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Locale;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {
	@Autowired
	private DataSource dataSource;
	
	@RequestMapping(value = "/jdbc1.do" )
	public String jdbc1(Locale locale, Model model) {
		System.out.println( "dataSource : " + dataSource );
		
		Connection conn = null;

	}
	
}

 

 

 

4.2 JdbcTemplate 이용

다른 방법으로 데이터베이스에 연동해보자.

(참고 : blog.naver.com/rnalsttnn2/222186074127 )

 

jdbcTemplate란 스프링에서 제공하는 SQL 연산들을 수행할 수 있도록 도와주는 JDBC 코드용 기본 템플릿이다.

jdbcTemplate의 기능에는 JDBC드라이버로드, 데이터베이스 연결, sql query, 데이터베이스 연결해제 등이 있다.

 

사용법은 다음과 같다.
1. pom에 dependency 추가

2. servlet-context.xml에 bean생성

3. Controller.java에 jdbcTemplate 선언하고 setter 메서드 추가

4. contant 클래스 만들고 public static jdbcTemplate 선언
5. dao에 jdbcTemplate 이용하여 메서드 생성

 

주로 3가지 메서드를 이용하여 게시판을 만들 수 있다.
- update() : 주로 sql 연산을 통해 데이터베이스를 갱신시켜줄 때 사용한다.
- queryForObject() : select쿼리를 실행하여 한 개의 객체를 받아올 때 사용한다.
- query() : 많은 결과 값(로우값)을 처리할 수 있는 메서드이다.

 

query( 1. sql문, 2. new BeanPropertyRowMapper<각 로우의 타입>(각 로우의타입.class), 3. 인자값 );

1. sql문 : 말 그대로 sql문이고 preparedStatement도 사용가능하다.

2. 는 1의 결과가 리턴되는 타입이다. resultSet으로 사용할 수 있다.

3. 은 생략가능하며 1에서 preparedStatement로 사용되었을 경우 ? 값을 넣으면 된다.

-Homecontroller.java

package com.exam.web03;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Locale;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {
	@Autowired
	private DataSource dataSource;
	@Autowired
	private JdbcTemplate jdbcTemplate;
	
	@RequestMapping(value = "/jdbc1.do" )
	public String jdbc1(Locale locale, Model model) {
		System.out.println( "dataSource : " + dataSource );
		
		Connection conn = null;
		PreparedStatement pstmt = null;
		ResultSet rs = null;
		
		try {
			conn = dataSource.getConnection();
			String sql = "select now() as now";
			pstmt = conn.prepareStatement(sql);
			rs = pstmt.executeQuery();
			
			if( rs.next() ) {
				System.out.println( "현재 시간: " + rs.getString( "now" ) );
			}
			
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {
			if( rs != null ) try { rs.close(); } catch( SQLException e ) {}
			if( pstmt != null ) try { pstmt.close(); } catch( SQLException e ) {}
			if( conn != null ) try { conn.close(); } catch( SQLException e ) {}
		}
		
		
		return "jdbc1";
	}
	
	@RequestMapping(value = "/jdbc2.do" )
	public String jdbc2(Locale locale, Model model) {
		System.out.println( "jdbcTemplate : " + jdbcTemplate );
		
		String result = jdbcTemplate.queryForObject("select now()", String.class );
		System.out.println( "result : " + result );
		
		return "jdbc1";
	}
	
}

 웹브라우저에서 주소값을 jdbc2.do를 입력하면 아래와 같은 결과가 나온다.

 

 

이번에는 DAO를 만들어서 실행시켜보자.

src/main/java에 SampleDAO.java를 만든다.

package com.exam.web03;

import org.springframework.jdbc.core.JdbcTemplate;

public class SampleDAO {
	private JdbcTemplate jdbcTemplate;
	
	public SampleDAO( JdbcTemplate jdbcTemplate ) {
		this.jdbcTemplate = jdbcTemplate;
	}

	public String selectNow() {
		System.out.println( "jdbcTemplate : " + jdbcTemplate );
		return "";
	}
}

-Homecontroller.java

package com.exam.web03;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Locale;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {
	@Autowired
	private DataSource dataSource;
	@Autowired
	private JdbcTemplate jdbcTemplate;
	
	@RequestMapping(value = "/jdbc1.do" )
	public String jdbc1(Locale locale, Model model) {
		System.out.println( "dataSource : " + dataSource );
		
		Connection conn = null;
		PreparedStatement pstmt = null;
		ResultSet rs = null;
		
		try {
			conn = dataSource.getConnection();
			String sql = "select now() as now";
			pstmt = conn.prepareStatement(sql);
			rs = pstmt.executeQuery();
			
			if( rs.next() ) {
				System.out.println( "현재 시간: " + rs.getString( "now" ) );
			}
			
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {
			if( rs != null ) try { rs.close(); } catch( SQLException e ) {}
			if( pstmt != null ) try { pstmt.close(); } catch( SQLException e ) {}
			if( conn != null ) try { conn.close(); } catch( SQLException e ) {}
		}
		
		
		return "jdbc1";
	}
	
	@RequestMapping(value = "/jdbc2.do" )
	public String jdbc2(Locale locale, Model model) {
		System.out.println( "jdbcTemplate : " + jdbcTemplate );
		
		String result = jdbcTemplate.queryForObject("select now()", String.class );
		System.out.println( "result : " + result );
		
		return "jdbc1";
	}
	
	@RequestMapping(value = "/jdbc3.do" )
	public String jdbc3(Locale locale, Model model) {
		
		SampleDAO dao = new SampleDAO(jdbcTemplate);
		System.out.println( dao.selectNow() );
		
		return "jdbc1";
	}
	
}

 웹브라우저에서 jdbc3.do를 입력하면 아래와 같은 결과가 나온다.

 

이번에는 DAO에서 생성자로 직접 jdbcTemplate객체를 주지 말고 Autowired로 사용해보자.

-SampleDAO.java

package com.exam.web03;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;

@Repository
public class SampleDAO {
	
	@Autowired
	private JdbcTemplate jdbcTemplate;
	
	/*
	 * public SampleDAO( JdbcTemplate jdbcTemplate ) { this.jdbcTemplate =
	 * jdbcTemplate; }
	 */

	public String selectNow() {
		System.out.println( "jdbcTemplate : " + jdbcTemplate );
		return "";
	}
}

-HomeController.java

package com.exam.web03;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Locale;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {
	@Autowired
	private DataSource dataSource;
	@Autowired
	private JdbcTemplate jdbcTemplate;
	@Autowired
	private SampleDAO dao;
	
	@RequestMapping(value = "/jdbc1.do" )
	public String jdbc1(Locale locale, Model model) {
		System.out.println( "dataSource : " + dataSource );
		
		Connection conn = null;
		PreparedStatement pstmt = null;
		ResultSet rs = null;
		
		try {
			conn = dataSource.getConnection();
			String sql = "select now() as now";
			pstmt = conn.prepareStatement(sql);
			rs = pstmt.executeQuery();
			
			if( rs.next() ) {
				System.out.println( "현재 시간: " + rs.getString( "now" ) );
			}
			
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {
			if( rs != null ) try { rs.close(); } catch( SQLException e ) {}
			if( pstmt != null ) try { pstmt.close(); } catch( SQLException e ) {}
			if( conn != null ) try { conn.close(); } catch( SQLException e ) {}
		}
		
		
		return "jdbc1";
	}
	
	@RequestMapping(value = "/jdbc2.do" )
	public String jdbc2(Locale locale, Model model) {
		System.out.println( "jdbcTemplate : " + jdbcTemplate );
		
		String result = jdbcTemplate.queryForObject("select now()", String.class );
		System.out.println( "result : " + result );
		
		return "jdbc1";
	}
	
	@RequestMapping(value = "/jdbc3.do" )
	public String jdbc3(Locale locale, Model model) {
		
		//SampleDAO dao = new SampleDAO(jdbcTemplate);
		System.out.println( dao.selectNow() );
		
		return "jdbc1";
	}
	
}

 다시 브라우저에서 jdbc3.do를 입력하면 아래와 같이 결과가 나온다.
