I am little bit confused by these three logger libraries.我对这三个记录器库有点困惑。 It seems like that they can do the similar thing in java logging...似乎他们可以在java日志中做类似的事情......

SLF4J - The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction ¹ for various logging frameworks (eg java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time. SLF4J - Java 的简单日志外观 (SLF4J) 作为各种日志框架（例如 java.util.logging、logback、log4j）的简单外观或抽象¹ ，允许最终用户在部署时插入所需的日志框架。

^{1) It is not itself a logging library, but a generic interface to one of many logging libraries.} ^{1) 它本身不是一个日志库，而是许多日志库之一的通用接口。}

Log4j 1.2 - Welcome to Apache log4j, a logging library for Java. Log4j 1.2 - 欢迎使用 Apache log4j，一个 Java日志库。

Logback - Logback is intended as a successor to the popular log4j project, picking up where log4j leaves off. Logback - Logback旨在作为流行的 log4j项目的继承者，从 log4j停止的地方开始。

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. Log4j 2 - Apache Log4j 2 是对 Log4j的升级，它比其前身 Log4j 1.x 提供了重大改进，并提供了 Logback 中可用的许多改进，同时修复了 Logback 架构中的一些固有问题。

At least, that's what they all say of themselves.至少，他们都是这样评价自己的。
