在mybatis打印Sql语句

在 mybatis-config.xml中配置settings

<?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> <!-- 打印查询语句 --> <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> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:com/jstudio/user/dao/*.xml"></property> </bean>
