解决方案1：控制器层次@ExceptionHandler

public class FooController{
     
    //...
    @ExceptionHandler({ CustomException1.class, CustomException2.class })
    public void handleException() {
        //
    }
}

解决方案2：统一的The HandlerExceptionResolver

1.ExceptionHandlerExceptionResolver
2.DefaultHandlerExceptionResolver
3.ResponseStatusExceptionResolver

@ResponseStatus

@ResponseStatus(value = HttpStatus.NOT_FOUND)
public class MyResourceNotFoundException extends RuntimeException {
    public MyResourceNotFoundException() {
        super();
    }
    public MyResourceNotFoundException(String message, Throwable cause) {
        super(message, cause);
    }
    public MyResourceNotFoundException(String message) {
        super(message);
    }
    public MyResourceNotFoundException(Throwable cause) {
        super(cause);
    }
}

4.custom HandlerExceptionResolver

@Component
public class RestResponseStatusExceptionResolver extends AbstractHandlerExceptionResolver {
 
    @Override
    protected ModelAndView doResolveException(
      HttpServletRequest request, 
      HttpServletResponse response, 
      Object handler, 
      Exception ex) {
        try {
            if (ex instanceof IllegalArgumentException) {
                return handleIllegalArgument(
                  (IllegalArgumentException) ex, response, handler);
            }
            ...
        } catch (Exception handlerException) {
            logger.warn("Handling of [" + ex.getClass().getName() + "] 
              resulted in Exception", handlerException);
        }
        return null;
    }
 
    private ModelAndView 
      handleIllegalArgument(IllegalArgumentException ex, HttpServletResponse response) 
      throws IOException {
        response.sendError(HttpServletResponse.SC_CONFLICT);
        String accept = request.getHeader(HttpHeaders.ACCEPT);
        ...
        return new ModelAndView();
    }
}

解决方案3：@ControllerAdvice

ControllerAdvice
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {
    @ExceptionHandler(value 
      = { IllegalArgumentException.class, IllegalStateException.class })
    protected ResponseEntity<Object> handleConflict(
      RuntimeException ex, WebRequest request) {
        String bodyOfResponse = "This should be application specific";
        return handleExceptionInternal(ex, bodyOfResponse, 
          new HttpHeaders(), HttpStatus.CONFLICT, request);
    }
}

解决方案4：ResponseStatusException

@GetMapping(value = "/{id}")
public Foo findById(@PathVariable("id") Long id, HttpServletResponse response) {
    try {
        Foo resourceById = RestPreconditions.checkFound(service.findOne(id));
 
        eventPublisher.publishEvent(new SingleResourceRetrievedEvent(this, response));
        return resourceById;
     }
    catch (MyResourceNotFoundException exc) {
         throw new ResponseStatusException(
           HttpStatus.NOT_FOUND, "Foo Not Found", exc);
    }
}

解决方案5：customAccessDeniedHandler

@Component
public class CustomAccessDeniedHandler implements AccessDeniedHandler {
 
    @Override
    public void handle
      (HttpServletRequest request, HttpServletResponse response, AccessDeniedException ex) 
      throws IOException, ServletException {
        response.sendRedirect("/my-error-page");
    }
}
//configure
@Component
public class CustomAccessDeniedHandler implements AccessDeniedHandler {
 
    @Override
    public void handle
      (HttpServletRequest request, HttpServletResponse response, AccessDeniedException ex) 
      throws IOException, ServletException {
        response.sendRedirect("/my-error-page");
    }
}
//accessDeniedException
@ControllerAdvice
public class RestResponseEntityExceptionHandler 
??extends ResponseEntityExceptionHandler {
?
????@ExceptionHandler({ AccessDeniedException.class })
????public ResponseEntity<Object> handleAccessDeniedException(
??????Exception ex, WebRequest request) {
????????return new ResponseEntity<Object>(
??????????"Access denied message here", new HttpHeaders(), HttpStatus.FORBIDDEN);
????}
?????
????...
}

解决方案6：ErrorController

//custom ErrorController
@Component
public class MyCustomErrorAttributes extends DefaultErrorAttributes {
 
    @Override
    public Map<String, Object> getErrorAttributes(
      WebRequest webRequest, boolean includeStackTrace) {
        Map<String, Object> errorAttributes = 
          super.getErrorAttributes(webRequest, includeStackTrace);
        errorAttributes.put("locale", webRequest.getLocale()
            .toString());
        errorAttributes.remove("error");
 
        //...
 
        return errorAttributes;
    }
}
//BasitController
@Component
public class MyCustomErrorAttributes extends DefaultErrorAttributes {
 
    @Override
    public Map<String, Object> getErrorAttributes(
      WebRequest webRequest, boolean includeStackTrace) {
        Map<String, Object> errorAttributes = 
          super.getErrorAttributes(webRequest, includeStackTrace);
        errorAttributes.put("locale", webRequest.getLocale()
            .toString());
        errorAttributes.remove("error");
 
        //...
 
        return errorAttributes;
    }
}
