问题描述

我对这三个记录器库有点困惑。看起来他们可以在java日志记录中做类似的事情......

I am little bit confused by these three logger libraries. It seems like that they can do the similar thing in java logging...

推荐答案

查看他们的主页：

SLF4J - 用于Java的简单日志外观（SLF4J）用作各种日志框架的简单外观或抽象 ¹ （例如java.util.logging，logback，log4j） ）允许最终用户在部署时插入所需的日志记录框架。

SLF4J - The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction¹ 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.

^{1）它本身不是一个日志库，而是一个通用接口许多日志库。}

Log4j 1.2 - 欢迎使用Apache log4j，一个用于Java的日志库。

Logback - Logback 打算作为热门log4j的继承者项目，选择log4j离开的地方。

Logback - Logback is intended as a successor to the popular log4j project, picking up where log4j leaves off.

Log4j 2 - Apache Log4j 2是升级到Log4j ，与其前身Log4j 1.x和相比提供了重大改进提供了Logback 中提供的许多改进，同时修复了Logback架构中的一些固有问题。

Log4j 2 - Apache Log4j 2 is an upgrade to Log4j that provides significant improvements over its predecessor, Log4j 1.x, and provides many of the improvements available in Logback while fixing some inherent problems in Logback's architecture.

至少，这就是他们自己所说的。
