Question

如果我在应用程序中遇到任何异常，它将显示在eclipse控制台上。但是，该异常未显示在tomcat logs文件夹中的日志文件中。我在这里缺少什么吗？

以下是我的完整log4j文件。

Answer 1

我认为您应该发布打印异常堆栈跟踪的代码检查您是否使用e.printStackTrace();代替Logger.error("some message", e);

Answer 2

将此文件保存在基目录

中

src / com.yourproject.web ... then：

的src /的log4j.xml

它有效!!!

为什么log4j没有在tomcat的日志中显示错误消息？
