In Spring Boot, you can utilize annotations from the JSR 303 specification to validate request parameters. The specific steps are as follows:<\/p>\n

    \n
  1. Add validation annotations like @Validated and @NotBlank before the request method parameters in the Controller class.<\/li>\n<\/ol>\n
    @RestController<\/span>\r\n@RequestMapping(\"\/api\")<\/span>\r\n@Validated<\/span>\r\npublic<\/span> class<\/span> UserController<\/span> {\r\n    \r\n    @PostMapping(\"\/user\")<\/span>\r\n    public<\/span> ResponseEntity<String> createUser<\/span>(@Valid<\/span> @RequestBody<\/span> UserDto userDto)<\/span> {\r\n        \/\/ \u5904\u7406\u8bf7\u6c42\u53c2\u6570<\/span>\r\n        return<\/span> ResponseEntity.ok(\"User created successfully\"<\/span>);\r\n    }\r\n}\r\n<\/code><\/pre>\n
      \n
    1. Create a DTO class to encapsulate request parameters, and add validation annotations to the properties of the DTO class.<\/li>\n<\/ol>\n
      public<\/span> class<\/span> UserDto<\/span> {\r\n\r\n    @NotBlank(message = \"Name is mandatory\")<\/span>\r\n    private<\/span> String name;\r\n\r\n    @Email(message = \"Email should be valid\")<\/span>\r\n    private<\/span> String email;\r\n\r\n    \/\/ getter and setter<\/span>\r\n}\r\n<\/code><\/pre>\n
        \n
      1. Define a global exception handler in the Controller class to capture validation errors and return error messages.<\/li>\n<\/ol>\n
        @ControllerAdvice<\/span>\r\npublic<\/span> class<\/span> GlobalExceptionHandler<\/span> {\r\n\r\n    @ExceptionHandler(MethodArgumentNotValidException.class)<\/span>\r\n    @ResponseStatus(HttpStatus.BAD_REQUEST)<\/span>\r\n    @ResponseBody<\/span>\r\n    public<\/span> ResponseEntity<String> handleValidationException<\/span>(MethodArgumentNotValidException ex)<\/span> {\r\n        BindingResult<\/span> result<\/span> =<\/span> ex.getBindingResult();\r\n        List<String> errorMessages = result.getAllErrors().stream()\r\n                .map(DefaultMessageSourceResolvable::getDefaultMessage)\r\n                .collect(Collectors.toList());\r\n        return<\/span> ResponseEntity.badRequest().body(String.join(\", \"<\/span>, errorMessages));\r\n    }\r\n}\r\n<\/code><\/pre>\n
        In this way, when the validation of the request parameters fails, the corresponding error message will be returned. Spring Boot automatically validates the request parameters and throws a MethodArgumentNotValidException exception when the validation fails, the global exception handler will capture this exception and return the error message.<\/p>\n","protected":false},"excerpt":{"rendered":"
