我正在开发一个vert.x应用程序。具体来说，我使用的是Java + Eclipse + Maven + Vert.x.我读到JUL是首选的日志框架，而vertx.log保存在/ tmp下（我是一个linux用户）。实际上，我想使用log4j并在自定义日志文件夹下生成不同的日志文件。我怎样才能做到这一点？ vert.x文档说（http://vertx.io/manual.html#logging）：
如果您不想使用Vert.x提供的日志工具，那很好。您可以正常使用首选日志记录框架，并在模块中包含日志记录jar和配置。
所以我尝试将log4j依赖项包含到我的pom.xml中，复制src / main / resources中的log4j.xml文件并在Verticle类中定义一个logger变量，但是控制台不会打印任何内容。我哪里做错了？
谢谢你， 弗朗西斯

这里是官方主题：https://groups.google.com/forum/#!topic/vertx/xhA9Gze1LM4
作者正在调查它为什么不起作用。与此同时，他建议使用：
-Dlog4j.configuration=file:./your_path/log4j.xml
答案 1 :(得分：1)
The manual还解释了如何在vertx.sh脚本中设置系统属性。所以，对于log4j：
-Dorg.vertx.logger-delegate-factory-class-name=org.vertx.java.core.logging.impl.Log4jLogDelegateFactory
这应确保Vert.x的日志记录通过log4j并获取您的配置。
（类似地，有一个SLF4JLogDelegateFactory实现，如果您编写可能在其他上下文中重用的代码，这可能是更好的选择。）
