Which of the following is used to mapCustom Exceptions to Statuscode?

In Spring MVC, the @ResponseStatus annotation is used to map custom exceptions to specific HTTP status codes. When an exception is thrown, you can use this annotation to indicate which status code should be returned. For example, if you have a custom exception that represents a resource not found scenario, you can annotate it with @ResponseStatus and specify HttpStatus.NOT_FOUND as the status code. This will result in a 404 status code being returned when the exception is thrown.

References:The use of @ResponseStatus is covered in the EC-Council’s Certified Application Security Engineer (CASE) JAVA training and certification program, which emphasizes the importance of secure application development practices across the Software Development Lifecycle (SDLC). The annotation is also widely documented in Spring MVC resources and tutorials, such as those available on Baeldung and Stack Overflow12.
