The thing is that the developers did not follow any pattern where to introduce the bussines logic so you can image multiples services call from the controller and after that some extra call to private method into the

问题 I have created my new custom annotation @MyCustomAnnotation @Target({ElementType.METHOD, ElementType.TYPE, ElementType.FIELD}) @Retention(RUNTIME) public @interface MyCustomAnnotation{ } I applied that annotation on component and bean.

问题 I have a WebMVC endpoint: @RequestMapping(path = "/execution/{id}", method = RequestMethod.POST) public ResponseEntity<...> execute(@PathVariable String id) { ... } Here, the provided id should be decoded first.

问题 I know there is some similar questions here about how to parse ENUM, how to parse customize JSON structure. But here my question is how to just give a better message when the user submit some JSON with is not as expected. This is the code: @PutMapping public ResponseEntity updateLimitations(@PathVariable("userId") String userId, @RequestBody LimitationParams params) { Limitations limitations = user.getLimitations(); params.getDatasets().forEach(limitations::updateDatasetLimitation); params
