java - Lombok 中的 @XSlf4j 和 @Slf4j 注释有什么区别？

Question

有人可以解释一下lombok.extern.slf4j.XSlf4j和lombok.extern.slf4j.Slf4j之间的区别吗？看起来XSlf4j是一个新添加的，为什么这个新注释被添加到Lombok库中。

Answer 1

一个注释会生成普通记录器，另一个注释会生成扩展记录器。

Lombok 为 xslf4j 注释生成此代码(此代码来自 https://projectlombok.org/api/lombok/extern/slf4j/XSlf4j ):

 private static final org.slf4j.ext.XLogger log = org.slf4j.ext.XLoggerFactory.getXLogger(LogExample.class);

XLogger 是一个扩展记录器，请参阅 https://www.slf4j.org/extensions.html ，它有一个以此摘要开头的描述:

The XLogger class provides a few extra logging methods that are quite useful for following the execution path of applications. These methods generate logging events that can be filtered separately from other debug logging. Liberal use of these methods is encouraged as the output has been found to

• aid in problem diagnosis in development without requiring a debug session
• aid in problem diagnosis in production where no debugging is possible
• help educate new developers in learning the application.
