Get ServletContext from MessageContext in interceptor

Question

How can I get an object of ServletContext from the MessageContext supplied in an interceptor? The TODO below is suppose to be a 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

You can try the following:

@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);
