mybatis配置log4j打印sql日志

前提是你已经配置好了log4j.

1. 在mybatis的配置文件中设置

   <?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>       <setting name="logImpl" value="LOG4J"></setting>   </settings>...</configuration>

   ​

2. 在log4j.properties文件中设置日志级别到debug或者更低

   ### 设置###log4j.rootLogger = debug,stdout,D,E

   ​

足矣。
