In Spring Boot, exception handling refers to the process of handling exceptions that may be thrown when the application is running. This is important because it allows you to provide a user-friendly and appropriate response to any errors that may occur, rather than just showing a raw error message to the user.
To handle exceptions in Spring Boot, you can use the @ExceptionHandler annotation to define a method that will be called whenever an exception of a specific type is thrown. This method can then perform any necessary actions, such as logging the error, sending an email to the administrator, or displaying a custom error message to the user.
You can also use the @ControllerAdvice annotation to define a global exception handler that will be called for any exception that is thrown in the application, regardless of the type.
