3. root-context.xml

네임스페이스 beans, context, jdbc, mybatis-spring, tx 선택

MyBatis 연동을 위한 bean 등록 및 의존관계 설정

Data source bean

Oracle/Mysql

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
	  <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"  />
	  <property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl" />
	  <!-- 오라클 사용자 이름 -->
	  <property name="username" value="MINDI"/>
	  <!-- 오라클 사용자 비밀번호 -->
	  <property name="password" value="admin"/>
	  <property name="validationQuery" value="SELECT 1" />
</bean>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="com.mysql.cj.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://127.0.0.1:3306/kko?autoReconnection=true;allowPublicKeyRetrieval=true&amp;useSSL=false&amp;serverTimezone=UTC" />
    <property name="username" value="webcompiler" />
    <property name="password" value="admin" />
    <property name="maxActive" value="5" />
    <property name="validationQuery" value="SELECT 1" />
    <property name="testWhileIdle" value="true" />
</bean>

MyBatis SqlSessionFactory bean

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <!-- mybatis-config.xml 파일 위치 설정 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
        <!-- Mapper 파일 위치 설정 -->
        <property name="mapperLocations" value="classpath:mappers/Mapper.xml"></property>
</bean>

MyBatis Spring SqlSessionTemplate bean

<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate" destroy-method="clearCache">
        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg>
</bean>

트랜잭션 관리 객체

<!-- 트랜젝션 관리 객체 -->
<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
</bean>

transaction annotation

<!-- @Transactional 어노테이션 처리 -->
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>

4. mybatis-config.xml

src/main/resources에 mybatis-config.xml 파일 생성

typeAliase: 매핑 파일에서 지정하는 자바클래스에 대한 별칭을 할당

앞으로 사용할 Mapper 파일에서 parameterType 이나 resultType에 사용하는

클래스 이름에 typeAliases에 등록한 이름을 생략할 수 있다.

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
  
<configuration>
  <typeAliases>
        <package name="org.kpu.web.domain" />
  </typeAliases>   
</configuration>

5. mapper.xml 작성

src/main/resources 에 mappers 폴더 - Mapper.xml 파일 생성

namespace 에는 Mapper.xml 의 경로

<?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="org.kpu.web.mapper.Mapper">
</mapper>
