Spring Web Application：如果初始化失败，则关闭

Question

I have a Spring web application. When the application context has started I use ApplicationListener<ContextRefreshedEvent> to perform some application initalization, in particular I load data from a web service. If this web service is not reachable then my application cannot do anything useful and it does not make sense to keep it running. Is there a way to programmatically shutdown the application context?

I have tried to do the following:

if (contextRefreshedEvent instanceof ConfigurableApplicationContext)
{
    ConfigurableApplicationContext configurableApplicationContext
            = (ConfigurableApplicationContext) contextRefreshedEvent;
    configurableApplicationContext.close ();
}

However rather then closing gracefully that produces the following exception:

java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext

So what is the proper way to shutdown the application in such a situation?

Throw an ApplicationContextException . It worked for me with Spring 4.2.7.RELEASE
