这是我的服务方法，它调用save（）方法：

@Override
public Contact addUser(UserForm userForm) {

    String encodedPassword;
    Contact user = userForm.getUser();

    //encode the password
    encodedPassword = encoder.encode(userForm.getPassword());

    //set the encoded password as the password
    user.setPassword(encodedPassword);

    Set<Role> securityRoles = new HashSet<Role>();

    //get Role
    securityRoles.add(roleDao.findById(userForm.getRoleId()));

    user.setRoles(securityRoles);

    user.setTenantId(securityAccessor.getCurrentLoggedUser().getTenantId());

    //now save
    return contactDao.save(user);
}

我已经进行了检查，以确保填充了“用户”对象属性（即firstName，lastName，tenantId），并可以确认它们是否存在。

任何帮助都感激不尽。

这是其余的相关代码。...

Mysql“联系人”表的图像，以显示TENANT_ENT_ID列：

Answer 1

我只是遇到了同样的问题，在我的情况下，问题是我用@NotNull批注标记了实体中的一个属性，但没有为其提供任何默认值。 因此删除表，删除注释，然后在没有notNull约束的情况下构造表，对我来说一切正常。 要么删除表并在没有NN（notNull）约束的情况下重建表，要么为TANENT_ENT_ID提供默认值（我不知道如何...在Google中查找它）将解决您的问题。

Answer 2

就我而言，问题是主键列未设置为AUTO_INCREMENT

这是我解决的方法：

alter table department modify column id int NOT NULL AUTO_INCREMENT;

Answer 3

对我来说，问题是，我在表中有一个额外的id字段，不能为null 。 愚蠢的错误。

Answer 4

在我的情况下，将数据库中的id字段设置为auto_increment解决了该问题。

Answer 5

修改表table_name修改列Column_id int主键AUTO_INCREMENT;

在这种情况下，如果要添加和AUTO_INCREMENT，则必须应用PK，Notnull等任意一个键来解决此问题...

Answer 6

我通过将实体的GenerationType从“ IDENTITY”更改为“ AUTO”来解决它，并且在数据库中，将my_Field更改为“ AUTOINCREMENT”属性。

Answer 7

使用默认值1更新@Column属性**columnDefinition = "int default 1"** 。

@Column(name = "TENANT_ENT_ID", nullable = false, columnDefinition = "int default 1")
private int tenantId;

使用xx.hbm.xml的另一种配置。

提及parent列和child列的默认值均为1 。

首先，您需要删除子表和父表。 然后重新启动服务器（Tomcat）。

SELECT * FROM `child`;
SELECT * FROM `parent`;
