mybatis sql日记输出

mybatis sql日志输出
网上转抄的做法还是ibatis那样，对java.sql.Connection的日志做输出，不知道这些人到底有没有去试过
正确做法如下
1. 标注里写SQL

package org.mybatis.example;public interface BlogMapper {  @Select("SELECT * FROM blog WHERE id = #{id}")  Blog selectBlog(int id);}

日志输出配置如下

log4j.logger.org.mybatis.example.BlogMapper=DEBUG

2. Mapper文件

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapper  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"  "http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.xx.blogMapper">  <select id="selectBlog" parameterType="int" resultType="Blog">    select * from Blog where id = #{id}  </select></mapper>

日志输出配置如下

log4j.logger.com.xx.blogMapper=DEBUG
