我正在开发一个在 WildFly 上运行的 Web 应用程序，该应用程序使用 SLF4J 和 Log4j 2 作为日志记录系统。在有关 Log4j 2 的 Apache 页面上，我了解到在 Web 应用程序中使用 log4j-web 模块的优点 ( Using Log4j 2 in Web Applications )，因此我添加了它，从那时起 WildFly 拒绝部署(这就是我在下面的列表中将其注释掉的原因)。
所以，我的问题是:是否建议将 log4j-web 模块与 WildFly 一起使用？如果是，我该如何设置它以与 WindFly 一起使用？
以下是相关列表:

最佳答案
这是一个common bug与 wildfly 8.x 一起使用，并且仅针对 wildfly 9.x
Log4j2 2.1 及以上版本在 wildFly 8.x 中会出现部署错误。
Log4j2 2.0.2 没有此错误，但有其他阻止程序错误 (LOG4J2-832)
关于java - WildFly 8 和 Log4j 2 的 log4j-web 模块，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28438228/
