Validations,Errors & Exceptions

 How can we handle exception in spring boot rest application?

• Start by identifying the type of exception that might occur, example, only custom exceptions or Built in ones.
• Create a custom exception, handler class for specific error scenarios.
• Utilise controller advice, annotation to create a global exception handler
• Define methods with @ ExceptionHandler Annotation
• Each handling a specific exception type.
• These will return meaningful response, types with HTTP status code and error message.
