mybatis3.2.8配置log4j2打印sql

一、环境

mybatis版本3.2.8，log4j2版本为2.2，采用spring集成mybatis

二、gradle中配置mybatis和log4j2

//log4j2
def log4j_version = "2.2";
compile "org.apache.logging.log4j:log4j-api:$log4j_version"
compile "org.apache.logging.log4j:log4j-core:$log4j_version"
compile "org.apache.logging.log4j:log4j-web:$log4j_version"
compile "org.apache.logging.log4j:log4j-slf4j-impl:$log4j_version"

//mybatis
compile "org.mybatis:mybatis:3.2.8"
compile "org.mybatis:mybatis-spring:1.2.2"

三、log4j2.xml中配置

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %l %msg%n"/>
</Console>

</Appenders>

<Loggers>
<Root level="error">
<AppenderRef ref="Console"/>
</Root>
<Logger name="com.mango.mapper" level="TRACE" additivity="false">       //为dao mapper所在的包，level为TRACE
<AppenderRef ref="Console"/>
</Logger>
</Loggers>
</Configuration>

四、Spring配置文件中配置

<!-- sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 数据库连接池 -->
<property name="dataSource" ref="dataSource" />
<!-- 加载mybatis的全局配置文件 -->
<property name="configLocation" value="classpath:sqlMapConfig.xml" />
</bean>

<!-- sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 数据库连接池 -->
<property name="dataSource" ref="dataSource" />
<!-- 加载mybatis的全局配置文件 -->
<property name="configLocation" value="classpath:sqlMapConfig.xml" />
</bean>

<!-- mapper扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 扫描包路径，如果需要扫描多个包，中间使用半角逗号隔开 -->
<property name="basePackage" value="com.mango.mapper"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />     //采用mapper文件的方式
</bean>

五、mybatis配置文件指定log4j2为日志输出

<settings>
<setting name="logImpl" value="LOG4J2" />
</settings>

六、打印日志如下
