1、在mybatis-config.xml中配置加一個(gè)setting

沒(méi)有改文件可以新增一個(gè)，內(nèi)容如下：

<?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>
        <!-- 打印查詢(xún)語(yǔ)句 -->
        <setting name="logImpl" value="STDOUT_LOGGING" />
    </settings>
</configuration>

2、在spring集成mybatis的sqlSessionFactory配置configLocation屬性

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

3、完成
