Postgresql 添加新用户Spring Boot/Postman时出现问题

你能帮我吗？向数据库添加新客户端时遇到问题

我有三个类：用户、角色、中心

我的用户类包含：

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String login;
private String password;
private String nom;
private String prenom;
private String telephone;
private String email;
private long idCCMS;
private String matricule;

@ManyToOne
@JoinColumn(name = "Code_Role")
private Role role;

@ManyToOne
@JoinColumn(name = "Code_Centre")
private Centre centre;

我的方法：

@PostMapping(value = "/add")
public Utilisateur save(@RequestBody Utilisateur user) {
    return userRepo.save(user);
}

如何通过为新用户分配角色和中心来影响其添加。 我和邮递员试过这个解决方案：

{
    "login": "med",
    "password": "123456789",
    "nom": "AOUIDIDI",
    "prenom": "MOHAMED WALID",
    "telephone": "(+222) 22-222-222",
    "email": "aaa@aaa.com",
    "idccms": 08318915,
    "matricule": "431908",
    "code_role":"3",
    "code_centre":"3"
}

我得到了这个结果：

你能帮我解决这个问题吗？

正如你的回答所说：

…行：8，列：16。。。无效的数值：不允许前导零

“idccms”：08318915

无法解析为

专用长idccms

要么在开始时去掉
0
，要么将
idCCMS
设置为
字符串的一种类型，一切都会很好。
“idCCMS”：08318915
。您可以发出“不拖尾零”的请求吗？堆栈跟踪错误非常明显。您的一个值是
08318915
，不是有效的数字我将“idccms”的类型从Long改为String，但当添加新用户时，它会将其放入数据库中的一个空字段这是我请求的结果：{“id”：1，“login”：“med”，“password”：“123456789”，“nom”：“AOUIDIDI”，“prenom”：“MOHAMED WALID”，电话：“（+222）22-222-222”，“电子邮件”：aaa@aaa.com，“idCCMS”：null，“矩阵”：“431908”，“角色”：null，“中心”：null}我不知道您如何在数据库中保存数据，因此我无法回答您的数据库字段未被填充的原因。
@Entity
中的字段名称应与数据库中的列名称相对应。请尝试将
@column（Name=“exact\u column\u Name\u in\u DB”）
放在字段
私有字符串idCCMS；
