I have struggled web service with this over the years. Let me present the typical scenario that I have seen. Your team starts working on some shiny new web service, and of course it is going to be REST. In the initial development, there are lots of errors—all kinds 404, 400, 30X, etc… Then as those bugs are found and fixed, the restful web service web service begins to stabilize. Soon, the only error you get back is the Internal Server (500) error. So what does the 500 error provide you in its vanilla form? Well, not really all that much. There is no detailed information available. You are left to note the error and then review the logs later. Is this really the best way to do REST error handling? The short answer is no it is not! Fortunately, there is an approach that can be used for REST Error Handling to provide detailed information for the dreaded 500 error. Let's start with an overview of how the REST Error Handling can be done. First, we will begin with the server side, which is where the error will first occur. In the controller we are going to want to catch the exceptions thrown up by the services, and convert those into an error response, but with some additional information included in the body. The additional information will allow for the error to be re-created on main persistence with Spring guides here at Baeldung. Security The main Spring Security guides here at Baeldung.

Error Handling for REST with Spring Last modified: July 20, 2016 REST, Spring by Eugen Paraschiv If you're new here, join the next webinar: "CQRS AND EVENT SOURCING" . Thanks for visiting! I just announced the Master Class of my "REST With Spring" Course: >> THE "REST WITH SPRING" CLASSES Table of Contents 1. Overview 2. Via Controller level @ExceptionHandler 3. Via HandlerExceptionResolver 4. Via new @ControllerAdvice (Spring 3.2 and Above) 5. Handle the Access Denied in Spring Security 6. Conclusion 1. Overview This article will illustrate how to implement Exception Handling with Spring for a REST API. We'll look at both the recommended solution with Spring 3.2 and 4.x but also at the older options as well. Before Spring 3.2, the two main approaches to handling exceptions in a Spring MVC application were: HandlerExceptionResolver or the @ExceptionHandler annotation. Both of these have some clear downsides. After 3.2 we now have the new @ControllerAdvice annotation to address the limitations of the previous two solutions. All of these do have one thing in common - they deal with the separation of concerns very well. The app can throw exception normally to indicate a failure of some kind - exceptions which will then be handled separately. 2. Solution 1 - The Controller level @ExceptionHandler The first solution works at the @Controller level - we will define a method to handle exceptions, and annotate that with @ExceptionHandler: public class FooController{ ... @ExceptionHandler({ CustomException1.class, CustomException2.class }) public void handleException() { // } } This approach has a major drawback - the @ExceptionHandler annotated method is only active for that particular Controller, Rest Client Error Handling
