在将新对象保存到Users表时,我在此方法调用上有 MySQLIntegrityConstraintViolationException

sessionFactory.getCurrentSession.save(newUser);

我在MySQL中有3个表。 UsersRolesAccounts

Users表具有Roles的外键:User.roleId -> Roles.roleId 一对多。主键userId

Accounts表具有Users的外键:Accounts.accountId -> Users.userId 一对一。主键accountId

创建新的用户对象

@Override
    public void registerUser(Registration reg) {
        User newUser = new User();
        newUser.setUsername(reg.getEmail());
        newUser.setPassword(reg.getPassword());

        genericDao.put(newUser);
        Integer userId = genericDao.getByName(User.class, "username", reg.getEmail()).get(0).getUserId();
        genericDao.put(new Account(userId));
    }

我在genericDao.put(newUser);方法调用上有异常。在这个方法里面只有我不创建的sessionFactory.getCurrentSession().save(obj); Role个对象。因此User.accountUser.role为NULL。还在MySQL中配置了默认值。

User.java


@Entity
@SuppressWarnings("unused")
@Table(name = "Users", uniqueConstraints = @UniqueConstraint(columnNames = "username"))
public class User implements Serializable, UserDetails{

    private static final long serialVersionUID = 6475100100480917262L;

    @Id
    @Column(name = "userId", length = 10)
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer userId;

    @JoinColumn(name = "roleId", nullable = true, updatable = false)
    @ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.REMOVE)
    private Role role;

    @OneToOne(mappedBy = "user", fetch = FetchType.LAZY, cascade = CascadeType.REMOVE)

    private boolean accountNonExpired;

    @Column(name = "nonLocked")
    private boolean accountNonLocked;

    @Column(name = "credentialsNonExpired")
    private boolean credentialsNonExpired;

    @Column(name = "enabled")
    private boolean enabled;

    //Getter and setters
}

Role.java


@Entity
@SuppressWarnings("unused")
@Table(name = "Roles")
public class Role implements Serializable, GrantedAuthority, Cloneable {

    private static final long serialVersionUID = 3586090230433600805L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "roleId", length = 10, unique = true, nullable = false)
    private Integer roleId;


    @Column(name = "role", length = 45, unique = true, nullable = true)
    private String  role;

    @OneToMany(cascade = CascadeType.REMOVE, fetch = FetchType.EAGER, mappedBy = "role")
    private Set usetSet = new HashSet(0);

    //Getters and setters
}

Account.java


@Entity
@Table(name = "Accounts")
@SuppressWarnings("unused")
public class Account implements Serializable {

    private static final long serialVersionUID = -7045300306954075788L;

    @Id
    @GenericGenerator(name = "generator", strategy = "foreign",
        parameters = @Parameter(name = "property", value = "user"))
    @GeneratedValue(generator = "generator")
    @Column(name = "accountId", length = 10, nullable = false)
    private Integer accountId;

    @Column(name = "firstName", length = 45, nullable = true)
    private String firstName;

    @Column(name = "lastName", length = 45, nullable = true)
    private String lastName;

    @Column(name = "gender", nullable = true)
    private Boolean gender;

    @Temporal(TemporalType.DATE)
    @Column(name = "birthDate", nullable = true)
    private Date birthDate;

    @Column(name = "profilePhoto", length = 250, nullable = false)
    private String profilePhoto;

    @PrimaryKeyJoinColumn
    @OneToOne(fetch = FetchType.EAGER, cascade = CascadeType.REFRESH)
    private User user;

    //Getters and setters
}

这个类的所有地方我都使用默认构造函数。

异常非常明确:角色列(在表Roles中)可能不为null。给定堆栈跟踪,我假设您正在保存与角色关联的用户,并且此角色具有空role字段。由于您将关联配置为级联,因此角色也会保存,并且由于它具有空role,因此插入失败。

编辑:新错误显示数据库中的列Users.roleId不能为空。所以你必须在savinf之前为你的用户设置一个角色。在数据库中为此列指定默认值是没有用的,因为只有在insert语句中没有为此列指定值时才会使用默认值。但是Hibernate总是会指定一个值。默认值无论如何都是个坏主意,因为Hibernate没有意识到它们,因此在没有刷新它们的情况下不能将它们放在实体中。

附注:如果不从实体上的注释生成数据库模式,则不应指定这些注释的可空,唯一,长度属性。特别是如果它们与数据库中的实际列定义相矛盾。当列实际上不可为空时,使用nullable=true注释的列会使事情变得非常混乱。
