by

Stumbled upon this question while searching exactly this. Finally I found out that it works in Spring 3.1 using @EnableWebMVC in conjunction with WebMvcConfigurerAdapter.

How can I send request again in response interceptor?

by

Here is my solution using promises for those interested. Basically you need to request a new session, and wait for the response before sending a new request corresponding to the original request (using response.config).

Is there a way to intercept setters and getters in C#?

Not generally; a few options though; inherit from ContextBoundObject – which does allow this, but at a performance cost write an explicit property (i.e. with a backing field), and add a utility method call manually look at compile-time weavers, such as PostSharp – generally by spotting an attribute or similar look at runtime code generators, … Read more

Java config for spring interceptor where interceptor is using autowired spring beans

Just do the following: @EnableWebMvc @Configuration public class WebConfig extends WebMvcConfigurerAdapter { @Bean LocaleInterceptor localInterceptor() { return new LocalInterceptor(); } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(localeInterceptor()); } } Of course LocaleInterceptor needs to be configured as a Spring bean somewhere (XML, Java Config or using annotations) in order for the relevant field of WebConfig … Read more

How to pass a param to HttpInterceptor?

by

Maybe there’s a better way to handle this problem, but as a workaround you can create and pass custom HttpParams to request and then check them in the interceptor.
