8. root-context.xml 수정 <?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:mybatis-spring="http://mybatis.org/schema/mybatis-spring"
xsi:schemaLocation="http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsd

<!-- Root Context: defines shared resources visible to all other web components -->
<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
<property name="driverClassName" value="net.sf.log4jdbc.sql.jdbcapi.DriverSpy"></property>
<property name="jdbcUrl" value="jdbc:log4jdbc:oracle:thin@localhost:1521:XE"></property>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
</bean>
<mybatis-spring:scan base-package="com.test.mapper" />

root-context.xml은 내부적으로 Log4jdbc를 이용하는 방식으로 구성되어 있어
src/main/resources에 'log4jdbc.log4j2.properties' 파일을 추가
log4jdbc.spylogdelegator.name=net.sf.log4jdbc.log.slf4j.Slf4jSpyLogDelegator
끝!
