项目中用到的一个log4j2.xml的配置文件：

 涉及到的pom.xml中的配置如下

             
                 
      
       org.slf4j
                  
      
       slf4j-api
                  
      
       1.7.19
              
             
                 
      
       org.apache.logging.log4j
                  
      
       log4j-slf4j-impl
                  
      
       2.5
              
             
                 
      
       org.apache.logging.log4j
                  
      
       log4j-api
                  
      
       2.5
              
             
                 
      
       org.apache.logging.log4j
                  
      
       log4j-core
                  
      
       2.5
              
             
                 
      
       org.apache.logging.log4j
                  
      
       log4j-jcl
                  
      
       2.5
              
     

 在类中如下写：

import org.slf4j.Logger;import org.slf4j.LoggerFactory;private final Logger logger = LoggerFactory.getLogger(this.getClass());
