如何在Spring Boot中验证pathparam值范围

如何解决如何在Spring Boot中验证pathparam值范围

我试图在我的一个PUT api中验证“短”数据类型路径参数，以便如果传递的值大于32767，则应返回正确的错误。

控制器：

@RestController
@RequestMapping("/myapp/")
@Validated
public class EmpController {
    @RequestMapping(value = "/employees/{empId}",method = RequestMethod.PUT,produces = "application/json")
    @ResponseBody
    public EmpResponse updateEmp(@PathVariable(value = "empId") @Max(value = 32767,message = "emp id can't be greater than 32767") short empId,@RequestBody EmpDetails empDetails) {
        Emp emp = service.updateEmp(empId,empDetails);
        logger.info("EmpDetails are updated for emp id:{}",empId);
        return this.convertToDto(emp);
    }
}

MethodValidationPostProcessor：-

@Bean
    public MethodValidationPostProcessor methodValidationPostProcessor() {
        return new MethodValidationPostProcessor();
    }

ControllerAdvice如下：

@ControllerAdvice
public class EmpGlobalExceptionHandler extends ResponseEntityExceptionHandler {
    @ExceptionHandler(value = { ConstraintViolationException.class })
    @ResponseStatus(value = HttpStatus.BAD_REQUEST)
    public String handleResourceNotFoundException(ConstraintViolationException e) {
        Set<ConstraintViolation<?>> violations = e.getConstraintViolations();
        StringBuilder strBuilder = new StringBuilder();
        for (ConstraintViolation<?> violation : violations ) {
            strBuilder.append(violation.getMessage() + "\n");
        }
        return strBuilder.toString();
    }
}

我尝试调试我的应用程序，但是执行不在控制器建议方法之内。

任何人都可以帮助获取代码中的问题。

谢谢
