[FIXED] How can i use multiple interceptors for specific request such as POST, Get and PUT?

Issue

I am using spring boot and cloud in the project. For logging, I am using Interceptors. Since I am new to interceptors I am having difficulty using multiple interceptors. Like can I use a specific interceptor for the specific task? For example, when I request a post, the POST interceptor is called, when I use GET the get interceptor is called. and how can I code for multiple interceptors too?

I never tried anything yet for that because I am not getting the logic

Solution

You can define all HTTP interceptors that you want, every interceptor should implement the logic of intercept an HTTP request.

@Slf4j
@Component
public class GetRequestInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        if (request.getMethod().equals(HttpMethod.GET.name())) {
            log.info("intercepting GET request {}", request.getRequestURI());

        }

        return true;
    }
}


@Slf4j
@Component
public class PostRequestInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        if (request.getMethod().equals(HttpMethod.POST.name())) {
            log.info("intercepting POST request {}", request.getRequestURI());
        }

        return true;
    }
}

And then you have to register them in spring.

@RequiredArgsConstructor
@Configuration
public class WebConfigurer implements WebMvcConfigurer {

    private final GetRequestInterceptor getInterceptor;
    private final PostRequestInterceptor postRequestInterceptor;


    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(getInterceptor);
        registry.addInterceptor(postRequestInterceptor);
    }

}
