spring集成mybatis后，需要打印SQL语句

mybatis-config.xml中配置一下信息:<?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>
