Error Handling Spring Integration
HandlerExceptionResolverJune 29, 2016 by Pankaj 20 Comments Spring MVC Exception Handling is very important spring mvc error handling to make sure you are not sending server exceptions to client. Today we will look into Spring Exception Handling using @ExceptionHandler, @ControllerAdvice and spring exception handling 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
Spring Error Handling Example
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 Exc

The Spring framework 3 provides an annotation @ExceptionHandler that can be used to intercept uncaught/unhandled exceptions in request mapped functions in controllers. In the example below, we are throwing an Exception from a method that is called whenever /example is called. When spring determines that an uncaught exception is being thrown by the method, it calls the errorResponse method as it is annotated with @ExceptionHandler. The errorResponse method can then be used to construct a JSON response (which in this case is a result of serializing a Map containing error message and exception stacktrace). This approach is ideal as it helps us reuse and centralize exception/error handling in Spring MVC/REST controllers.@Controller @RequestMapping(value="/example") public class ExampleController { @RequestMapping(value = "", method = RequestMethod.POST) @ResponseBody public void example() throws Exception{ System.out.println("in the example function"); throw new Exception("a new Exception"); } @ExceptionHandler(Exception.class) @ResponseBody public Map

Normally, we use @ExceptionHandler to decide which "view" should be returned back if certain exception is error handling raised.P.S This @ExceptionHandler class is available since Spring 3.01. Project StructureReview the project directory structure, a standard Maven project. 2. Custom ExceptionA custom exception, with custom error code and error description.CustomGenericException.java package com.mkyong.web.exception; public class CustomGenericException extends RuntimeException { error handling spring private static final long serialVersionUID = 1L; private String errCode; private String errMsg; public String getErrCode() { return errCode; } public void setErrCode(String errCode) { this.errCode = errCode; } public String getErrMsg() { return errMsg; } public void setErrMsg(String errMsg) { this.errMsg = errMsg; } public CustomGenericException(String errCode, String errMsg) { this.errCode = errCode; this.errMsg = errMsg; } } 3. Spring ControllerA Spring controller, review the execution-flows below :If user provide a /error request, it throws "CustomGenericException", and the handleCustomException() method will be fired. If user provide a /io-error request, it throws "IOException", and the handleAllException() method will be fired.MainController.java package com.mkyong.web.controller; import java.io.IOException; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.

IntroductionWe might have been across some of the several ways by which we can handle exceptions in a RESTful web service application in Spring. In this article, we will try to explore the best approach we can take to achieve efficient exception handling.2. Problem StatementLet’s create a simple application that will identify the employee name in the REST URI. If the employee name provided in the request is numeric, let our application throw a custom exception, which we will be handling through the Exception Handlers, and accordingly return the JSON response to the client. The success response will be the JSON with employee details, while the failure response will be an error JSON with errorCode and the proper error message.3. ImplementationLet’s first check out how our pom file entries and web.xml look like –pom.xml
