mybatis 打印SQL语句

方法一:

在mybatis-config.xml中配置加一个setting

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>
    <settings>
        
        <setting name="logImpl" value="STDOUT_LOGGING" />
    settings>
configuration>

如果是spring集成mybatis的话,在sqlSessionFactory配置好configLocation属性

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation" value="classpath:conf/mybatis-config.xml">property>
        
        <property name="mapperLocations" value="classpath:com/jstudio/user/dao/*.xml">property>
bean>

 

方法二:

首先将ibatis log4j运行级别调到DEBUG可以在控制台打印出ibatis运行的sql语句 

###显示SQL语句部分
log4j.logger.com.ibatis=DEBUG
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.Java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
