8.SpringBoot : Spring Boot, you can handle global exceptions | Interview Question

In Spring Boot, you can handle global exceptions using the @ControllerAdvice annotation along with @ExceptionHandler methods. Here's how you can handle global exceptions in Spring Boot:

Create an Exception Handler Class:

Create a class annotated with @ControllerAdvice. This class will contain methods to handle exceptions globally.

Define Exception Handling Methods:

Inside the class, define methods annotated with @ExceptionHandler to handle specific types of exceptions. You can have multiple exception handling methods to handle different types of exceptions.

Return Response Entity or Model and View:

From the exception handling methods, you can return a ResponseEntity or a ModelAndView object to provide a custom response to the client.

In this example:

The GlobalExceptionHandler class is annotated with @ControllerAdvice.

There are two exception handling methods: handleException() to handle general exceptions and handleResourceNotFoundException() to handle a custom ResourceNotFoundException.

Each method returns a ResponseEntity with an appropriate HTTP status code and a custom error message.

With this setup, whenever an exception of the specified type occurs within any controller method in your Spring Boot application, the corresponding exception handling method in the GlobalExceptionHandler class will be invoked to handle it.
