无法在Controller中调试@ExceptionHandlerConstraintViolationException.class-Spring Boot

问题描述

有什么方法可以调试如下所示的异常处理程序，从邮递员传递无效请求不会导航到异常处理程序方法？

@RequestMapping("api/v1/employee")
@RestController
public class EmployeeController {

    private final EmployeeService employeeService;

    public EmployeeController(EmployeeService employeeService) {
        this.employeeService = employeeService;
    }

    @GetMapping({"/{empId}"})
    public ResponseEntity<EmployeeDto> getEmployeeById(@PathVariable("empId") UUID empId) {
        return new ResponseEntity<>(employeeService.getEmployeeById(empId),HttpStatus.OK);
    }

    @SuppressWarnings({ "rawtypes","unchecked" })
    @PostMapping
    public ResponseEntity createEmployee(@Valid @RequestBody EmployeeDto employeeDto) {
        EmployeeDto savedEmployeeDto = employeeService.saveNewEmployee(employeeDto);
        HttpHeaders headers = new HttpHeaders();
        headers.add("Location","api/v1/employee/" + savedEmployeeDto.getId().toString());
        return new ResponseEntity(headers,HttpStatus.CREATED);
    }

    @SuppressWarnings({ "rawtypes"})
    @PutMapping({"/{empId}"})
    public ResponseEntity updateEmployee(@PathVariable("empId") UUID empId,@Valid @RequestBody EmployeeDto employeeDto) {
        employeeService.updateEmployee(empId,employeeDto);
        return new ResponseEntity(HttpStatus.NOT_IMPLEMENTED);
    }

    @DeleteMapping({"/{empId}"})
    @ResponseStatus(HttpStatus.NOT_IMPLEMENTED)
    public void deleteEmployee(@PathVariable("empId") UUID empId){
        employeeService.deleteEmployeeById(empId);
    }

    @ExceptionHandler(ConstraintViolationException.class)
    private ResponseEntity<List<String>> validationErrorHandler(ConstraintViolationException ex) {
        List<String> validationErrors = new ArrayList<>(ex.getConstraintViolations().size());
        ex.getConstraintViolations().forEach(violation -> {
            validationErrors.add(violation.getPropertyPath() + "_" + violation.getMessage());
        });
        return new ResponseEntity<>(validationErrors,HttpStatus.BAD_REQUEST);
    }

}

传递无效请求不会在响应中显示验证错误。
