在重新发布到JBoss之前，如何运行方法？ [英] How do I run a method before republishing to JBoss?

问题描述

我正在开发J2EE Web应用程序，并希望能够在重新发布过程中运行方法（或函数，类，任何 - 某些）。如果我可以在重新发布我的函数被调用（之前，之后，之后等）时控制，但是第一步将是自动调用某些东西。

作为一个临时黑客，我可以在点击Eclipse中的重新发布之前点击右键添加一个按钮。

解决方案

实现 ServletContextListener 挂钩webapp的启动和关闭。

  public class Config实现ServletContextListener {
 
 public void contextInitialized（ServletContextEvent event）{
 //启动时做东西
} 
 
 public void contextDestroyed（ServletContextEvent event）{
 //在关闭期间进行填充。 
} 
 
} 
  

要使其正常工作，只需在 web.xml 中注册。

 < listener> 
< listener-class> com.example.Config< / listener-class> 
< / listener> 
  

然而，我不知道在发布期间你的意思是什么。但是您可以查看Servlet API中可用的其他侦听器，也可以查看过滤器。

I'm developing a J2EE web application and I would like to be able to run a method (or function, class, whatever - something) during the "republish" process. It would be nice if I could control when during the republish my function gets called (before, during, after, etc.) but a good first step would be getting something to be called automatically.

As a temporary hack, I was able to add a button to my web app that you click right before you click "republish" in Eclipse.

解决方案

Implement ServletContextListener to hook on webapp's startup and shutdown.

public class Config implements ServletContextListener {

    public void contextInitialized(ServletContextEvent event) {
        // Do stuff during startup.
    }

    public void contextDestroyed(ServletContextEvent event) {
        // Do stuff during shutdown.
    }

}

To get it to work, just register it in web.xml.

<listener>
    <listener-class>com.example.Config</listener-class>
</listener>

I am however only not sure what exactly you mean with during publish. But you could take a look for another listeners available in the Servlet API or maybe a Filter.
