Access a request scoped Bean in Service

Question

I have a regular bean, which is either (a) @Scope(\"request\") or (b) placed in a HttpServletRequest via Filter/ Interceptor.

How to access thi

Answer 1

As long as the bean is declared as request scope, Spring will take care of the rest.

@Bean
@Scope(value = WebApplicationContext.SCOPE_REQUEST, proxyMode = ScopedProxyMode.TARGET_CLASS)
public RequestContext requestContext() {
    return new RequestContext();
}

Access the bean in the usual way, just autowire it.

@Autowired
private RequestContext requestContext;

The Service bean will be a sigleton but under the covers the RequestContext bean is attached to the thread so you will get a different instance each time a method is called.

NOTE YOU MUST HAVE A WEB CONTEXT, i.e. RUNNING A WEB SERVER/WEB APP
