ssm框架中，mybatis的sql语句日志输出
mybatis-config.xml配置
<?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>
注意：
在增加mybatis-config.xml后，需要在spring与mybatis的整合配置文件（spring-mybatis.xml）中增加映射才可生效，
如下：
<!-- spring和MyBatis整合--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mybatis配置文件 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:com/merch/mapping/*.xml"></property> </bean>
