idea mybatis配置log4j列印sql語句的樣本，mybatislog4j

在IDEA中配置log4j,步驟很簡單

1.在Maven中加入以下配置

<dependency>   <groupId>commons-logging</groupId>   <artifactId>commons-logging</artifactId>   <version>1.2</version>  </dependency>  <dependency>   <groupId>log4j</groupId>   <artifactId>log4j</artifactId>   <version>1.2.16</version>  </dependency>  <dependency>   <groupId>org.slf4j</groupId>   <artifactId>slf4j-api</artifactId>   <version>1.5.6</version>   <type>jar</type>  </dependency>  <dependency>   <groupId>org.slf4j</groupId>   <artifactId>slf4j-simple</artifactId>   <version>1.5.6</version>  </dependency>

2.編寫mybatis-config.xml檔案

<?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>  <!-- 列印查詢語句 -->  <setting name="logImpl" value="LOG4J" /> </settings></configuration>

3.編寫log4j.properties檔案

log4j.rootLogger=error, Console log4j.logger.com.wocus.wine.dao=debug #Consolelog4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.layout=org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n 

4.在掃描mapper的xml檔案中

 <!-- spring和MyBatis完美整合，不需要mybatis的配置對應檔 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  <property name="dataSource" ref="dataSource"/>  <!-- 自動掃描mapping.xml檔案 -->  <property name="mapperLocations" value="classpath:com.wocus.wine/dao/*Mapper.xml"/>  <!-- 配置log4j-->  <property name="configLocation" value="classpath:mybatis-config.xml"></property> </bean>

注意：IDEA中的日誌輸出在output中，如果需要篩選，快速鍵Ctrl+F

【拓展】

“細粒度”控制：Log4j列印出MyBatis中僅僅單個Mapper的配置。

<!-- 下面是通過配置log4j2，僅僅列印出單個mapper的SQL語句的配置--><logger name="com.beebank.dao.iface.UserMapper"> <level>DEBUG</level></logger>
