SLF4J学习

The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time.

一、首先贴上几个网址：

①slf4j官网：http://www.slf4j.org/index.html

②slf4j资源下载：http://www.slf4j.org/download.html

③slf4j用户指南：http://www.slf4j.org/manual.html

④slf4j常见问题：http://www.slf4j.org/manual.html

二、入门小程序

①导入jar包和xml文件

②入门代码

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

public class log_prac {

public static void main(String[] args) {

Logger logger = LoggerFactory.getLogger("log_prac.class");

logger.info("helloworld");

}

}
运行结果：

要导入xml文件否则报错
