在Springboot中拦截异常的Rest api

Question

i have a rest api:

@RestController

.....

@PostMapping(value = "/v1/ms/prop")
    public @ResponseBody ResponseEntity<Object> orch(@RequestBody @Valid Request request){
        
            
        

Response response = serv.prop(request);
            return ResponseEntity.ok(response);

and serv.prop(request):

Response response = new Response ();
    
    try {
        calculate(**data**);
        callExternalService();
    } catch (Exception e) {

   **//intercept status error code**
   **// writeError(data,errorStatusCode)**
        
    } finally {
        writeAuditOperation(auditLog);
        MDC.clear();
    }

Inside the catch, i want, ONLY IN this api rest, intercept the type of error (400,404,500,502 ecc ecc ) and call an external service that log this error.

Thanks for the help

Rather than manually handling Exceptions in your controller, you should try @ExceptionHandler .
