HandlerExceptionResolver¶

HandlerExceptionResolver is a component within the [[Spring MVC]] architecture that defines the strategy for resolving exceptions raised during handler mapping or handler execution^{[600-developer-java-spring-dispatcherservlet.md]}[600-developer__java__spring__DispatcherServlet.md].

It functions as one of the strategies utilized by the DispatcherServlet to manage error handling within the web request processing workflow^{[600-developer-java-spring-dispatcherservlet.md]}[600-developer__java__spring__DispatcherServlet.md].

Common Implementations¶

The Spring Framework typically configures several standard resolvers to handle different types of exceptions^{[600-developer-java-spring-dispatcherservlet.md]}[600-developer__java__spring__DispatcherServlet.md]:

• ExceptionHandlerExceptionResolver: Handles exceptions through @ExceptionHandler methods.
• ResponseStatusExceptionResolver: Supports exceptions annotated with @ResponseStatus.
• DefaultHandlerExceptionResolver: Converts standard Spring exceptions into HTTP status codes.
