spring - mybatis 세팅

가장먼저 라이브러리 업데이트를 해야된다.

maven 요즘 다들 쓰져?

pom.xml에 해당내용을 추가한다.

  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>3.2.4.RELEASE</version>
  </dependency>
  <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.1.26</version>
  </dependency>
  <dependency>
      <groupId>com.kenai.nbpwr</groupId>
      <artifactId>org-apache-commons-dbcp</artifactId>
      <version>1.2.2-201002241055</version>
  </dependency>
  <dependency>
     <groupId>org.mybatis</groupId>
     <artifactId>mybatis</artifactId>
     <version>3.2.2</version>
   </dependency>
   <dependency>
     <groupId>org.mybatis</groupId>
     <artifactId>mybatis-spring</artifactId>
     <version>1.2.0</version>
   </dependency>

 

저장하면 자동으로 라이브러리가 업데이트된다.

그후에 mybatis 환경파일을 만든다.

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
  
    <context:component-scan base-package="com.pgmman.webmvc"/>

    <context:property-placeholder location="classpath:jdbc.properties"/>
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
 
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="typeAliasesPackage" value="com.pgmman.webmvc.vo"/>
        <property name="mapperLocations" value="classpath*:com/pgmman/webmvc/mapper/*.xml"/>
    </bean>

    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg index="0" ref="sqlSessionFactory"/>
    </bean>
   
 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
   <property name="dataSource" ref="dataSource"/>
 </bean>
 <tx:annotation-driven transaction-manager="transactionManager" />

</beans>

 

중간에 환경파일이 하나 있을것이다 jdbc.properties 요놈을 생성해준다.

 

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost/gmProject
jdbc.username=비밀

jdbc.password=비밀

 

마지막으로 web.xml 에 해당 환경을 읽도록 추가해준다.

전부 다읽도록 수정했다.

 

 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
  /WEB-INF/spring/*-context.xml
  </param-value>
 </context-param>

 

테스트해야지.

 

테스트할 쿼리를 user.xml에 생성했다.

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="user">

  <select id="getUserList" resultType="UserInfoVO">
   SELECT user_id,user_name
   FROM user
  </select>

</mapper>

 

dao도 생성한다.

 

@Repository
public class UserInfoDao {

  @Autowired
  private SqlSession sqlSession;

  public List<UserInfoVO> getUserList() {

   return sqlSession.selectList("user.getUserList");

  }

}

 

service생성한다.

 

@Service
public class UserInfoService {

  @Autowired
  private UserInfoDao userInfoDao;

  public List<UserInfoVO> getUserList() {

   return userInfoDao.getUserList();

  }

}

 

Controller생성한다.

@Controller
public class BoardController {
 
 @Autowired
 private UserInfoService userInfoService;

 private static final Logger logger = LoggerFactory.getLogger(BoardController.class);
 
 @RequestMapping(value = "/board.gm", method = RequestMethod.GET)
 public String home(Locale locale, Model model) {
  logger.info("Welcome board!! 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 );
  model.addAttribute("userList", userInfoService.getUserList());

  return "board";
 }

}

 

화면 생성한다.

 

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" pageEncoding="utf-8" %>
<%
 //UserInfoVO user;
 //user = request.getAttribute("userList");
%>
<html>
<head>
 <title>Board</title>
</head>
<body>
<h1>
 Hello world! 
</h1>

<P>  The time on the server is ${serverTime}. </P>

    <c:forEach var='user' items='${userList}'>
     ${user.user_id}/${user.user_name}<br>
    </c:forEach>
</body>
</html>

 

자 그럼 보일것이다.

 

 

 

 

끝.
