slf4j + logback 输出日志：mybatis sql语句

1 引入jar包：maven resposity 中 选择logback classic module

 

    ch.qos.logback
    logback-classic
    1.2.3


2 添加logback.xml 配置文件

    
        
            %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
        
    

    
        d:/logs/carmall-manager.log
        
            d:/logs/carmall-manager.%d{yyyy-MM-dd}.log
        
        
            %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
        
    

    
    

    
    
    
    
    
    
    
    
    
    
    
        
        
        
        
    

　　最后输出日志

最近在项目中添加日志

如果是spring boot项目的话：
只要在application.properties里面加上

logging.level.com.你的包名=true。就ok
