Spring5新特性—Log4j2

创建一个Maven项目，导入依赖

    org.apache.logging.log4j
    log4j-core
    2.15.0



    org.apache.logging.log4j
    log4j-api
    2.15.0



    org.apache.logging.log4j
    log4j-slf4j-impl
    2.15.0
    test



    org.slf4j
    slf4j-api
    1.7.32



    org.slf4j
    slf4j-simple
    1.7.32

Log4j2.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>



    
    
        
        
            
            
        
    
    
    
    
        
            
        
    

编写一个测试类

package com.dzj.test;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class UserLog {

    private static final Logger log = LoggerFactory.getLogger(UserLog.class);

    public static void main(String[] args) {
        log.info("hello,dengzi");
        log.warn("hello,dengzi");
    }
}

测试结果：

[main] INFO com.dzj.test.UserLog - hello,dengzi
[main] WARN com.dzj.test.UserLog - hello,dengzi
// 2021-12-22 16:47:26.613 [main] INFO  UserLog - hello,dengzhijiang
// 2021-12-22 16:47:26.616 [main] WARN  UserLog - hello,dengzhijiang
