阅读更多

1.新建log4j2.xml，我是放在WEB-INF/config下

    
        /logs
        log
    
    
        
            
        
        
            
            
                
                
            
            

        
            
        
        
    
    
        
            
            
        
    

2.web.xml文件

    
        log4jConfiguration
        /WEB-INF/config/log4j2.xml
    
	
		org.apache.logging.log4j.web.Log4jServletContextListener
	
	
		log4jServletFilter
		org.apache.logging.log4j.web.Log4jServletFilter
	
	
		log4jServletFilter
		/*
		REQUEST
		FORWARD
		INCLUDE
		ERROR
	

3.pom.xml文件

			
				org.apache.logging.log4j
				log4j-core
				2.8.2
			
			
				org.apache.logging.log4j
				log4j-api
				2.8.2
			
			
			    org.apache.logging.log4j
			    log4j-web
			    2.8.2
			
			
				org.slf4j
				slf4j-api
				1.7.25
			
			
			    org.apache.logging.log4j
			    log4j-slf4j-impl
			    2.8.2
			

4.log4j2  配置slf4j后,将项目中的获取logger的方式修改一下即可

				 Logger logger = LogManager.getLogger(UserController.class); 改为
				 Logger logger = LoggerFactory.getLogger(UserController.class);

即可
