整合 slf4j 与 logback。

快速开始

maven 依赖

添加依赖包logback使用需要和slf4j一起使用，所以总共需要添加依赖的包有slf4j-api

logback使用需要和slf4j一起使用，所以总共需要添加依赖的包有slf4j-api.jar，logback-core.jar，logback-classic.jar，logback-access.jar这个暂时用不到所以不添加依赖了，maven配置

　　UTF-8
　　1.1.7
　　1.7.21



　　
        org.slf4j
        slf4j-api
        ${slf4j.version}
        compile
    
    
        ch.qos.logback
        logback-core
        ${logback.version}
    
    
        ch.qos.logback
        logback-classic
        ${logback.version}

logback.xml 配置

    
    
    
    
        
            
            %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
        
    
    
    
        
            
            ${LOG_HOME}/TestWeb.log.%d{yyyy-MM-dd}.log
            
            30
        
        
            
            %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
        
        
        
            10MB

或者一个更加简单的 logback.xml

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

测试代码

package com.github.houbb.zk.learn;

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

public class LoggerTest {

    private static Logger logger = LoggerFactory.getLogger(LoggerTest.class);

    public static void main(String[] args) {
        logger.debug("debug：....");
        logger.info("info...");
        logger.error("error...");
    }

}
