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>
