Question

У меня есть веб-службы RESTful в Springboot с конечной точкой определяется как:

@RequestMapping(
     value="/api/users", 
     method=RequestMethod.POST, 
     consumes=MediaType.APPLICATION_JSON_VALUE, 
     produces=MediaType.APPLICATION_JSON_VALUE) 
public ResponseEntity<User> createUser(
     @Valid @RequestBody User user, BindingResult result) { 
    if (result.hasErrors()) { 
     return new ResponseEntity<User>(user, HttpStatus.BAD_REQUEST); 
    } 
    User savedUser = userService.create(user); 
    return new ResponseEntity<User>(savedUser, HttpStatus.CREATED); 

} 

и схемы пользователя определяется как:

CREATE TABLE User (
    userId BIGINT GENERATED BY DEFAULT AS IDENTITY (START WITH 1, INCREMENT BY 1) NOT NULL, 
    username VARCHAR(100) NOT NULL UNIQUE, 
    password VARCHAR(100) NOT NULL, 
    email VARCHAR(100) NOT NULL UNIQUE, 
    mobile BIGINT NOT NULL UNIQUE, 
    PRIMARY KEY (userId) 
); 

Я хочу, чтобы пользователи с одинаковым именем пользователя или электронной почтой или мобильным телефоном не регистрировались. В моем Почтальон клиента, когда я делаю запрос POST с повторяющимися значениями, я получаю Внутренняя ошибка сервера 500 и на моей стороне сервера появляется следующая строка ошибок:

Может кто-нибудь сказать мне, что случилось? Почему я получаю 500 Internal Server Error, а не 400 Bad Request Error? Как это исправить?

Если пользователь выбирает имя пользователя (например), которое уже используется, я хочу, чтобы сервер отправил ответ, сообщающий ему об этом. Как мне это достичь? Скажите ему, что имя пользователя не уникально или электронная почта уже зарегистрирована (т. Е. Разные сообщения об ошибках для имени пользователя/электронной почты/мобильного телефона)?

Спасибо!

Answer 1

На стороне базы данных вам нужно указать имена для ограничений UNIQUE, чтобы их можно было использовать позже, чтобы указать, какое поле уже было в базе данных.

CREATE TABLE User (
userId BIGINT GENERATED BY DEFAULT AS IDENTITY (START WITH 1, INCREMENT BY 1) NOT NULL, 
username VARCHAR(100) NOT NULL, 
password VARCHAR(100) NOT NULL, 
email VARCHAR(100) NOT NULL, 
mobile BIGINT NOT NULL, 
CONSTRAINT PK PRIMARY KEY (userId), 
CONSTRAINT USERKEY UNIQUE(USERNAME), 
CONSTRAINT EMAILKEY UNIQUE(EMAIL), 
CONSTRAINT MOBILEKEY UNIQUE(MOBILE) 
); 

Я не знаю ответа на код возврата сервлета.
