我正在使用Eclipse Kepler,我在Jboss EAP 6.1中运行Java Web应用程序.今天早上我注意到在部署和运行我的Web应用程序后,没有控制台输出.

但控制台输出显示我何时启动Jboss并显示所有应用程序部署的所有内容等.但之后没有任何东西在控制台中打印.

可以有人请公会我可能是什么原因我尝试了在*中发布的不同-2问题中提到的大量事情.

更新： –

我试过下面的代码

public class test {

  public static void main(String arg[]){
    System.out.println("hariom");
  }
}

并且它的结果在控制台中打印但是当我部署和运行Web应用程序时,它只是没有显示任何内容.

解决方法:

问题将通过在服务器中添加以下VM参数来解决

请转到Eclipse->服务器选项卡 – >单击Open Launch Configuration – > VM参数

并在VM参数部分添加此参数

-Dorg.jboss.as.logging.per-deployment=false

这里有link更多关于这个问题的细节

After reading what has been said in this thread, I’m trying to
summarize the use of the per-deployment flag:

1.0 When per-deployment is true (default):

1.1 AS7.1.2 is scanning for logging configuration files in your deployment (WAR), If a configuration file is found then that
deployment will get its own log context and be configured via the
configuration file.

1.2 Once the properties file is found, it will be read and the application logging will go to wherever it has been specified to log
(with the corresponding handler).

1.3 Logging jars don’t need to be included with the application.

2.0 Setting the flag to false disables this feature, and the deployment scanner will not look for these files. Therefore:

2.1 You have to use the jboss-deployment-structure.xml to exclude the AS server’s logging dependencies you are using and include them into
your deployment.

2.2 Logging functionality is left up to the application. The application should have all the configuration files and required
libraries (That’s why the server’s libraries have to be excluded)

2.3 If the application had, for example, a log4j.xml but no log4j dependency. The application will stop logging.

Personally, I’m using -Dorg.jboss.as.logging.per-deployment=false when
I get missing dependencies errors at during deployment so that it
displays in the console the stack trace for the missing class.
Otherwise the only error we get in AS7’s console (and server.log) is:
Services with missing/unavailable dependencies Which does not make it easy to track down the missing
dependency.
