log4j2+mybaits 打印sql操作语句

1、log4j2依赖　　　

pom.xml
　　　　　<!-- log4j2 日志模块 -->
        <dependency>  
            <groupId>org.apache.logging.log4j</groupId>  
            <artifactId>log4j-api</artifactId>  
            <version>2.8.2</version>  
        </dependency>  
        <dependency>  
            <groupId>org.apache.logging.log4j</groupId>  
            <artifactId>log4j-core</artifactId>  
            <version>2.8.2</version>  
        </dependency> 
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-web</artifactId>
            <version>2.8.2</version>
        </dependency>

2、在resources目录下创建 log4j2.xml文件

log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO" monitorInterval="1800">
    <appenders>
        <Console name="consolePrint" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss} [%t] %-5level %logger{36} - %msg%n" />
        </Console>
    </appenders>
 
    <loggers>
        <!-- 将业务dao接口填写进去,并用控制台输出即可 -->
        <logger name="cn.zgmh.zxks.mapper.dao" level="DEBUG" additivity="false">
            <appender-ref ref="consolePrint"/>
        </logger>
 
        <root level="info">
            <appender-ref ref="consolePrint" />
        </root>
    </loggers>
</Configuration>

3、在web.xml中进行配置

  <!-- log4j2 日志 -->
  <context-param>  
    <param-name>log4jConfiguration</param-name> 
　　 <param-value>classpath:log4j2.xml</param-value>  
  </context-param>  
  <listener>  
    <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>  
  </listener> 

4、在mybatis配置文件中 配置

    <settings>
        <!-- 开启驼峰命名 -->
        <setting name="mapUnderscoreToCamelCase" value="true" />
        
        <!-- log4j2日志 -->
        <setting name="logImpl" value="LOG4J2" />
    </settings>

5、已经配置ok了。可以看下效果了
