我正在尝试启动 jBoss 服务器 (v4.2) 来运行并显示所有 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进行。
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";
}
最佳答案
我可以想到两种方法来让调试消息显示在此处:
1) 您可以在 xml 文件中为 ServerLogsController 添加新条目以显示 DEBUG 消息。
<category name="package.for.ServerLogsController">
<priority value="DEBUG" />
<appender-ref ref="CONSOLE"/>
<appender-ref ref="FILE"/>
</category>
将 package.for.ServerLogsController 替换为正确的包名称。请注意，您还可以将其设置为package.for，并且该目录下的所有文件都将记录@DEBUG级别。此设置将覆盖第二个项目符号中提到的 root 行为(即，如果 root 设置为 DEBUG 但 package.for.ServerLogsController 设置为 ERROR >，您将看不到来自 package.for.ServerLogsController 的 DEBUG 消息。
2)在根包上设置调试
<root>
<priority value="DEBUG"/>
<appender-ref ref="CONSOLE"/>
<appender-ref ref="FILE"/>
</root>
这将使所有包在 DEBUG 级别记录，除非被包明确覆盖。
关于java - Log4j 和 Jboss。如何显示 log.Debug ("Debug") 消息？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11090394/
