        src/main/resources 폴더 안에 

        log4jdbc.log4j2.properties 파일과 logback.xml, mybatis-config.xml 파일을 추가한다.

log4jdbc.log4j2.properties 안에 소스코드

log4jdbc.spylogdelegator.name=net.sf.log4jdbc.log.slf4j.Slf4jSpyLogDelegator

logback.xml 안에 소스코드

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>

    <!-- log4jdbc-log4j2 -->
    <logger name="jdbc.sqlonly"        level="DEBUG"/>
    <logger name="jdbc.sqltiming"      level="INFO"/>
    <logger name="jdbc.audit"          level="WARN"/>
    <logger name="jdbc.resultset"      level="ERROR"/>
    <logger name="jdbc.resultsettable" level="ERROR"/>
    <logger name="jdbc.connection"     level="INFO"/>
</configuration>

mybatis-config.xml 안에 소스코드

<?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>
  
  </configuration>

root-context.xml

1. 네임스페이스 추가.

beans, context, mybatis-spring 총 3가지 체크 확인.

2. SessionFactory, SqlSessionTemplate 추가.

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="net.sf.log4jdbc.sql.jdbcapi.DriverSpy"></property>
		<property name="url" value="jdbc:log4jdbc:mysql://127.0.0.1:3306/web"></property>
		<property name="username" value="bill"></property>
		<property name="password" value="bill"></property>
	</bean>
	
	
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="configLocation" value="classpath:/mybatis-config.xml" />
		<property name="mapperLocations" value="classpath:mappers/**/*Mapper.xml" />
	</bean>
	
	<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate" destroy-method="clearCache">
		<constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg>
	</bean> 
	
	<context:component-scan base-package="com.web.service"></context:component-scan>	
	<context:component-scan base-package="com.web.dao"></context:component-scan>
</beans>

service 와 dao에 component-scan 확인할 것!

컨트롤러는  servlet-context.xml에 추가할것

<context:component-scan base-package="com.web.controller" />
