When the exception is raised, the ResponseStatusExceptionResolver handles it by setting the status of the response accordingly.package com.memorynotfound.exception; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ResponseStatus; @ResponseStatus(value = HttpStatus.NOT_FOUND, reason = "Course not found") public Spring Rest Controller Exception Handling This is a convenience mechanism: by including the status code in the body, any REST client that processes the error has one and only one place to look to fully understand What's wrong with my code?

Spring Boot Exception Handling

Happy Spring Learning! We define a controller-local exception handler using the @ExceptionHandler annotation and return a ModelAndView containing the occurred exception and forward it to the error page.package com.memorynotfound.controller; import org.springframework.web.bind.annotation.*; import org.springframework.web.servlet.ModelAndView; @RestController Exception Handling In Spring Rest Services ElectricityNotFoundException.java package com.concretepage.exception; public class ElectricityNotFoundException extends RuntimeException { private static final long serialVersionUID = 1L; public ElectricityNotFoundException(String villageName) { super(villageName+":Electricity not available"); } } For the demo, we have a Spring Mvc Exception Handling Best Practices These are chained and processed in the order listed (internally Spring creates a dedicated bean - the HandlerExceptionResolverComposite to do this).
