我正在尝试启动我的 jBoss 服务器 (v4.2) 以运行并显示我的所有 log.debug 消息。我需要通过编辑 jboss 配置来实现这一点。不是通过应用程序以编程方式。

我的 jboss-log4.xml

我正在测试的页面

private static final Logger log = Logger.getLogger(ServerLogsController.class
  .getName());

@GET
  @Path("/testDebug")
  public String testDebug(@Context final ServletContext context)
  {
    log.error("This is an error which always shows!");
    log.debug("This is a debug message");

    return "Test Debug Page";
  }

There's two ways I can think of to get the debug messages to show here:

1) You can add a new entry in your xml file for ServerLogsController to display DEBUG messages.

<category name="package.for.ServerLogsController">
    <priority value="DEBUG" />
    <appender-ref ref="CONSOLE"/>
    <appender-ref ref="FILE"/>
</category>

where you replace package.for.ServerLogsController with the correct package name. Note that you can also set that to just package.for and all files under that directory will log @ DEBUG level. This setting will override the root behavior mentioned in the second bullet (i.e. if root is set to DEBUG but package.for.ServerLogsController is set to ERROR, you will not see DEBUG messages from package.for.ServerLogsController.

2) Set debugging on the root package

<root>
    <priority value="DEBUG"/>
    <appender-ref ref="CONSOLE"/>
    <appender-ref ref="FILE"/>
</root>

This will make all packages log at DEBUG level unless specifically overriden by a package.
