java - 使用 Spring JPA 将数据插入两个表抛出错误

Question

我有两张 table

1. tbl_user_info
2. tbl_user_auth

我试图按顺序在两个表中保存数据，但数据存储在第一个表中并抛出错误，如下所示:

{
    "timestamp": "2020-06-15T11:17:06.540+0000",
    "status": 500,
    "error": "Internal Server Error",
    "message": "could not execute statement; SQL [n/a]; constraint [null]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement",
    "path": "/user/register"
}

实体类如下:

1. 用户帐户

   @Entityd

   }
   

Controller :

@PostMapping("register") // Needed parameter : All except id and token
    public AuthResponse registerUser(@RequestBody UserAccount userAccount) throws NoSuchAlgorithmException {
        if (userAccount == null) throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "Request Body can not be null");
        jsonResponse = new JSONResponse();
        if (!userAccountService.isEmailPresent(userAccount.getEmail())){
             userAccount.setPassword(DigestUtils.md5Hex(userAccount.getPassword()));
             return userAccountService.registerUser(userAccount);
        }
        throw new ResponseStatusException(HttpStatus.BAD_REQUEST,"Email ID Already Exists");
    }

服务:

public AuthResponse registerUser(UserAccount userAccount) throws NoSuchAlgorithmException {
        UserAccount ua = userAccountRepository.save(userAccount);
        String token = tokenService.createToken((ua.getId()));
        //Saving the user id and newly created token in tbl_token_info
        ua.setToken(token);
        UserAccount ua1 = userAccountRepository.save(ua);
        UserAuthInfo userAuthInfo = new UserAuthInfo();
        userAuthInfo.setClientId(UtilityMethods.clientId);
        userAuthInfo.setUserId(ua.getId());
        String code = UtilityMethods.getCode(userAccount.getEmail(), userAccount.getPassword());
        userAuthInfo.setCode(code);
        String accessToken = UtilityMethods.getAccessToken(code);
        String refreshToken = UtilityMethods.getRefreshToken(code);
        userAuthInfo.setAccessToken(accessToken);
        userAuthInfo.setRefreshToken(refreshToken);
        userAuthInfo.setExpiresIn(3600);
        userAuthInfo = userAuthService.saveUserAuth(userAuthInfo);
        AuthResponse authResponse = new AuthResponse();
        authResponse.setAccessToken(userAuthInfo.getAccessToken());
        authResponse.setRefreshToken(userAuthInfo.getRefreshToken());
        authResponse.setExpiresIn(60);
        authResponse.setCreatedDateTime(UtilityMethods.getCurrentDateTime());
        return authResponse;
    }

请指导一下哪里出了问题。

Answer 1

您必须使用表之间的关系:

@OneToMany 用于表中的 1-N 组合关系。 @Embedded 表示 1-1 关系

@ManyToOne 用于表中的 N-1 关联关系。

不要使用双向关系。始终是单向的。

如果您不使用它，数据库的映射可能是错误的。
