mybatis在控制台打印sql语句

1：mybatis-config.xml中配置：

<?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>

2：spring-mvc中配置：

  <property name="configLocation" value="classpath:mybatis-config.xml"></property>
