如何从JAX-WS Web服务中访问ServletContext？ [英] How can I access the ServletContext from within a JAX-WS web service?

问题描述

我想通过将其存储为servlet上下文属性来共享我的servlet和我的webservice（JAX-WS）之间的对象。但是如何从Web服务中检索servlet上下文？

I want to share an object between my servlets and my webservice (JAX-WS) by storing it as a servlet context attribute. But how can I retrieve the servlet context from a web service?

推荐答案

JAX-WS通过以下方式提供servlet上下文消息上下文，可以使用Web服务上下文检索。插入以下成员将导致JAX-WS将Web服务上下文的引用注入Web服务：

The servlet context is made available by JAX-WS via the message context, which can be retrieved using the web service context. Inserting the following member will cause JAX-WS to inject a reference to the web service context into your web service:

import javax.annotation.Resource;
import javax.servlet.ServletContext;
import javax.xml.ws.WebServiceContext;
import javax.xml.ws.handler.MessageContext;

...

@Resource
private WebServiceContext context;

然后，您可以使用以下命令访问servlet上下文：

Then, you can access the servlet context using:

ServletContext servletContext =
    (ServletContext) context.getMessageContext().get(MessageContext.SERVLET_CONTEXT);
