Exception Handling In Spring Framework
requires good design for exception handling because we don't want to serve container generated page when any unhandled exception is thrown by our application.Spring Exception HandlingHaving a well defined exception handling approach is a huge plus point for any web application framework, that being said Spring MVC framework delivers spring framework 404 error well when it comes to exception and error handling in our web applications.Spring MVC Framework provides following ways to help us achieving robust exception handling.Controller Based - We can define exception handler methods in our controller classes. All we need is to annotate these methods with @ExceptionHandler annotation. This annotation takes Exception class as argument. So if we have defined one of these for Exception class, then all the exceptions thrown by our request handler method will have handled.These exception handler methods are just like other request handler methods and we can build error response and respond with different error page. We can also send JSON error response, that we will look later on in our example.If there are multiple exception handler methods defined, then handler method that is closest to the Exception class is used. For example, if we have two handler methods

Diggs Java Spring Framework / Spring MVCSpring MVC Exception Handlingby MemoryNotFound · Published May 18, 2016 · Updated May 18, 2016In this tutorial we take a look at how to use Spring MVC Exception Handling. We can design http://memorynotfound.com/spring-mvc-exception-handling/ our application to deal with exceptions in various ways. We could handle the exceptions in the methods where they occur, but most of the time http://www.concretepage.com/spring/spring-mvc/spring-mvc-exception-handling-with-exceptionhandler-responseStatus-handlerexceptionresolver-example-global-exception this leads to cluttered and duplicated exception handling code, so we are not showing you this. The following is an overview of what we'll error handling see in this article:Handling controller local exceptions - We can catch the exceptions using a @ExceptionHandler locally in the controller. This will override any pre-defined global exception handler.Global exception handler - Catch exceptions globally across all controllers.Custom 404 response - Instead of the default 404 page, we return a JSON error handling spring response containing a detailed message.Custom error pages - Instead of showing the default error pages of your servlet container, we create a custom error page displaying the occurred error message.Business Exceptions - by annotating custom business methods with @ResponseStatus spring automatically returns the status code defined in the annotation.Spring MVC Exception HandlingTo start, we are using the following Java Object to return a fault code together with a detailed message. As this class will be used across all examples, we show you this first. Later on we look at the previous examples into more detail.package com.memorynotfound.model; public class Error { private int code; private String message; public Error() { } public Error(int code, String message) { this.code = code; this.message = message; } public int getCode() { return code; } public String getMessage() { return message; } }Handling Controller Local ExceptionsUsing Spring MVC we can handl

We can handle exceptions using @ResponseStatus, @ExceptionHandler, HandlerExceptionResolver and @ControllerAdvice. @ResponseStatus defines a status code for the given exception and can be used at custom exception class level and method level with @ExceptionHandler in controller. In controller class, we can define handler method using @ExceptionHandler and this will be controller specific. To handle exception globally, spring provides @ControllerAdvice that will be available for every controller. Define a class for global exception and annotate it with @ControllerAdvice and we need to define methods using @ExceptionHandler annotation within the class. Spring provides one more approach to handle exception. Use HandlerExceptionResolver in spring XML or java configuration where we can define mappings of exception type and view name. Find the complete example with description. @ExceptionHandler @ExceptionHandler annotation handles exceptions in spring MVC. We annotate our controller methods by this annotation. That method can have arguments of type Exception, HttpServletRequest, HttpServletResponse, Session, WebRequest etc in any order. That can return ModelAndView, Model, Map, View, String, @ResponseBody and void. In case of return type void, we can redirect the response with the object of HttpServletResponse . @ResponseStatus @ResponseStatus can be applied on custom exception class or any controller method. It has two elements value and reason. Using value element, we assign the response status code like 404, 200 etc. Reason element is used for response. We can write a statement as a reason. HandlerExceptionResolver HandlerExceptionResolver is an interface that has different implementations to resolve exception thrown during execution. Some implementations are ExceptionHandlerExcept
