This video explains how to hand Generic Centralized Exception handling in Spring Boot using Restful Web Service. in order to implement exception handling we need to use the following class and annotation.
ResponseEntityExceptionHandler
@ControllerAdvice
For validation and exception handling we need to use ResponseEntityExceptionHandler. We need to create a new class by extending this class. In this class, we can implement several Generic exception handling methods. Those methods reused wherever exception throws in our Application. For example, the below method annotated with @ExceptionHandler and accepts a parameter as an exception type of class. here I am passing InvalidInputException. Inside the method body, we need to implement our exception-handling code. Now, this method is a generic method and we can reuse this method across in our application. Wherever InvalidInputException throws, those places following method get invoke and throw the InvalidinputException in client-side as a response. Don't forget to annotate with @ControllerAdvice at the class level.
@ExceptionHandler(InvalidInputException.class)
public final ResponseEntity invalidInputException(InvalidInputException ex, WebRequest request) throws Exception { }
This video shows a very simple example to understand Exception handling.
