海外TECH	DEV Community	Spring Boot Exception Handling example	https://dev.to/tienbku/spring-boot-exception-handling-example-241c	Spring Boot Exception Handling exampleIn this tutorial we re gonna look at an Spring Boot Exception Handling example that uses ControllerAdvice and ExceptionHandler You can also handle Restful API exception with RestControllerAdvice kindly visit RestControllerAdvice example in Spring BootThis article is originally posted at Bezkoder Rest API exception handlingWe ve created Rest Controller for CRUD Operations and finder method Let look at the code step by step to build the Rest APIs is in Spring Boot Data JPA H CRUD exampleSpring Boot Data JPA MySQL CRUD exampleSpring Boot Data JPA PostgreSQL CRUD exampleSpring Boot Data JPA SQL ServerSpring Boot Data JPA Oracle exampleSpring Boot MongoDB CRUD exampleSpring Boot Cassandra CRUD example RestControllerpublic class TutorialController Autowired TutorialRepository tutorialRepository GetMapping tutorials

NO CONTENT catch Exception e return new ResponseEntity amp lt gt HttpStatus INTERNAL SERVER ERROR DeleteMapping tutorials public ResponseEntity amp lt HttpStatus gt deleteAllTutorials try and catch GetMapping tutorials published public ResponseEntity amp lt List amp lt Tutorial gt gt findByPublished try and catch You can see that we use try catch many times for similar exception INTERNAL SERVER ERROR and there are also many cases that return NOT FOUND Is there any way to keep them simple any way to attach the error response message smartly and flexibility Let s solve the problem now Exception Handling with Controller Advice in SpringSpring supports exception handling by a global Exception Handler ExceptionHandler with Controller Advice ControllerAdvice This enables a mechanism that makes ResponseEntity work with the type safety and flexibility of ExceptionHandler ControllerAdvicepublic class ControllerExceptionHandler ExceptionHandler value ResourceNotFoundException class CertainException class public ResponseEntity amp lt ErrorMessage gt resourceNotFoundException ResourceNotFoundException ex WebRequest request ErrorMessage message new ErrorMessage status date ex getMessage description return new ResponseEntity amp lt ErrorMessage gt message HttpStatus NOT FOUND The ControllerAdvice annotation is specialization of Component annotation so that it is auto detected via classpath scanning A Controller Advice is a kind of interceptor that surrounds the logic in our Controllers and allows us to apply some common logic to them Its methods annotated with ExceptionHandler are shared globally across multiple Controller components to capture exceptions and translate them to HTTP responses The ExceptionHandler annotation indicates which type of Exception we want to handle The exception instance and the request will be injected via method arguments By using two annotations together we can control the body of the response along with status code handle several exceptions in the same method ResponseStatusIn the example above we use ControllerAdvice for REST web services and return ResponseEntity object additionally Spring also provides ResponseBody annotation which tells a controller that the object returned is automatically serialized into JSON and passed it to the HttpResponse object This way does not require ResponseEntity but you need to use ResponseStatus to set the HTTP status code for that exception ControllerAdvice ResponseBodypublic class ControllerExceptionHandler ExceptionHandler ResourceNotFoundException class ResponseStatus value HttpStatus NOT FOUND public ErrorMessage resourceNotFoundException ResourceNotFoundException ex WebRequest request ErrorMessage message new ErrorMessage return message Setup Spring Boot ProjectYou can follow step by step or get source code in one of following posts Spring Boot Data JPA H CRUD exampleSpring Boot Data JPA MySQL CRUD exampleSpring Boot Data JPA PostgreSQL CRUD exampleSpring Boot Data JPA SQL ServerSpring Boot Data JPA Oracle exampleSpring Boot MongoDB CRUD exampleSpring Boot Cassandra CRUD exampleThe Spring Project contains structure that we only need to add some changes to make the pagination work well Or you can get the new Github source code at the end of this tutorial The final project structure will be like this Define Error Response MessageWe want to create a our own message response structure instead of using default error response provided by Spring Boot Let s define a specific error response structure exception ErrorMessage javapackage com bezkoder spring exhandling exception import java util Date public class ErrorMessage private int statusCode private Date timestamp private String message private String description public ErrorMessage int statusCode Date timestamp String message String description this statusCode statusCode this timestamp timestamp this message message this description description public int getStatusCode return statusCode public Date getTimestamp return timestamp public String getMessage return message public String getDescription return description Create Custom ExceptionWe re gonna throw an exception for Resource not found in Spring Boot controller Lets create a ResourceNotFoundException class that extends RuntimeException exception ResourceNotFoundException javapackage com bezkoder spring exhandling exception public class ResourceNotFoundException extends RuntimeException private static final long serialVersionUID L public ResourceNotFoundException String msg super msg Create Controller Advice with ExceptionHandlerNow we re gonna create a special class which is annotated by ControllerAdvice annotation This class handles specific exception ResoureNotFoundException and global Exception in only one

Update a non existent tutorial Create tutorial with wrong fields Delete a non existent tutorial ConclusionToday we ve built a Exception Handling class for Spring Boot Rest APIs using ControllerAdvice and ExceptionHandler Now you can create your own custom exception handler class or handle global exception in single place at ease If you want to add Pagination to this Spring project you can find the
