Question

通过在@Startup标记的bean中的@PostConstruct标记方法中抛出异常，我当前能够在Glassfish 3.1服务器上部署应用程序时发出警告消息。但是，它仍然部署（因此它位于应用程序列表中），并且错误消息是一个相当模糊的消息，而不是与异常一起给出的消息。

我希望完全部署失败，并提供适当的消息，以指出出现了什么问题。如果没有自定义Glassfish服务器，这可以从标准Java EE中完成吗？如果是这样，怎么样？

当前设置是一个域应用服务器和两个实例。

当前给定的消息如下

Warning Command succeeded with Warning
"http://localhost:4848/management/domain/applications/application/applicationname" created successfully. WARNING: Command _deploy did not complete successfully on server instance instance1: remote failure: Failed to load the application on instance instance1. The application will not run properly. Please fix your application and redeploy. Exception while shutting down application container : java.lang.NullPointerException. Please see server.log for more details. WARNING: Command _deploy did not complete successfully on server instance instance1: remote failure: Failed to load the application on instance instance1. The application will not run properly. Please fix your application and redeploy. Exception while shutting down application container : java.lang.NullPointerException. Please see server.log for more details.

@PostConstruct

中使用的代码示例

@PostConstruct
public void init() throws ExceptionInInitializerError {
    throw new ExceptionInInitializerError("Don't deploy!");
}

也适用于

@PostConstruct
public void init() throws Exception {
    throw new Exception("Don't deploy!");
}

在RuntimeException

的情况下也是如此

@PostConstruct
public void init() {
    throw new RuntimeException("Don't deploy!");
}

我认为通往＆＃34;打破＆＃34;部署并抛出异常是使用JavaEE SPI扩展。

我正在使用这个，但它用于glassfish4
