从拦截器中的MessageContext获取ServletContext

Question

如何从拦截器中提供的MessageContext中获取ServletContext的对象？ 下面的TODO假设是一个ServletContext。

@Override
public boolean handleRequest(MessageContext messageContext, Object endpoint)
        throws Exception {

    WebApplicationContext applicationContext =
            WebApplicationContextUtils.getWebApplicationContext(TODO);
            TestIdentitiesService service = applicationContext.getBean(TestIdentitiesService.class);

Answer 1

您应该能够使用以下内容获取ServletContext：

messageContext.getProperty(HTTPConstants.MC_HTTP_SERVLETCONTEXT);

Answer 2

您可以尝试以下操作：

@Autowired
private ServletContext context;

@Override
public boolean handleRequest(MessageContext messageContext, Object endpoint)
        throws Exception {

    WebApplicationContext applicationContext =
            WebApplicationContextUtils.getWebApplicationContext(context);
    TestIdentitiesService service =
    applicationContext.getBean(TestIdentitiesService.class);
