NOTE: The demo applications has been revamped and updated (October 2014) to use Spring Boot 1.1.8 and is (hopefully) easier to use and understand.Using HTTP Status Codes Normally any unhandled exception thrown when processing a web-request causes the server to error message handler return an HTTP 500 response. However, any exception that you write yourself can be annotated with the @ResponseStatus annotation (which supports all the HTTP status codes defined by the HTTP specification). When an annotated exception is thrown from a controller method, and not handled elsewhere, it will automatically cause the appropriate HTTP response to be returned with the specified status-code. For example, here is an exception for a missing order. @ResponseStatus(value=HttpStatus.NOT_FOUND, reason="No such Order") // 404 public class OrderNotFoundException extends RuntimeException { // ... } And here is a controller method using it: @RequestMapping(value="/orders/{id}", method=GET) public String showOrder(@PathVariable("id") long id, Model model) { Order order = orderRepository.findOrderById(id); if (order == null) throw new OrderNotFoundException(id); model.addAttribute(order); return "orderDetail"; } A familiar HTTP 404 response will be returned if the URL handled by this method includes an unknown order id.Controller Based Exception HandlingUsing @ExceptionHandler You can add extra (@ExceptionHandler) methods to any controller to specifically h

To start with it, let us have working Eclipse IDE in place and follow the following steps to develope a Dynamic Form based Web Application using Spring Web Framework: StepDescription 1Create a Dynamic Web Project with a name HelloWeb and create a package com.tutorialspoint under the src folder in the created project. 2Drag and drop below mentioned Spring and other libraries into the folder WebContent/WEB-INF/lib. 3Create a Java classes Student, StudentController and SpringException under the com.tutorialspoint package. 4Create Spring configuration files Web.xml and HelloWeb-servlet.xml under the WebContent/WEB-INF folder. 5Create a sub-folder with a name jsp under the WebContent/WEB-INF folder. Create a view files student.jsp, result.jsp, error.jsp, and ExceptionPage.jsp under jsp sub-folder. 6The final step is to create the content of all the source and configuration files and export the application as explained belo

Today we will look into Spring Exception Handling using @ExceptionHandler, @ControllerAdvice and HandlerExceptionResolver. Any web application 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 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 defined for IOException and Exception and our request handler method throws IOException, then handler method for IOException will get executed.Global Exception Handler - Exception Handling is a cross-cutting concern, it should be done for all the pointcuts in our application. We have already looked into Spring AOP and that's why Spring provides @ControllerAdvice annotation that we can use with any class to define our global exception handler.The handler methods in Global Controller Advice is same as Controller based exception handler methods and used w
