我有一个Spring MVC
项目,带有Hibernate
注释实体映射。到目前为止,数据库已创建正常,保存新对象仍然没有问题。直到我添加了一个新的实体类。
当我尝试保存User
并更改日期字段(last_login
)时,会发生错误:
User u = userService.get(userDetails.getUsername());
u.setLast_login(new Timestamp((new java.util.Date()).getTime()));
spService.save(u.getRegisterPoint());
spService.save(u.getWorkSalePoint());//Because of another error
userService.update(u);
其中:
@Override
public boolean update(User user) {
try {
session().update(user);
} catch (Exception e) {
return false;
}
return true;
}
我尝试在关系中添加级联,尝试没有任何一个(他们工作正常,没有课程)。
User.java
@Entity
@Table(name = "USERS")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id_u;
@Column(name = "name")
private String name;
@Column(name = "last_login")
private Timestamp last_login;
@ManyToOne
@JoinColumn(name = "id_register_point", referencedColumnName = "id_sp")
SalePoint registerPoint;
@Transient
private int registerPoint_id;
@ManyToOne
@JoinColumn(name = "id_work_sp", referencedColumnName = "id_sp")
SalePoint workSalePoint;
//Getters and setters
}
SalePoint.java
@Entity
@Table(name = "SALEPOINTS")
public class SalePoint {
@Id
@Column(name = "id_sp")
@GeneratedValue(strategy = GenerationType.AUTO)
private int id_sp;
@Column(name = "name")
private String name;
@OneToMany(mappedBy = "registerPoint")
private Set<User> registeredClients;
@OneToMany(mappedBy = "workSalePoint")
private Set<User> workers;
@OneToMany(mappedBy = "salePoint")
private Set<Order> orders;
//Getters and Setters
}
Status.java
@Entity
@Table(name = "STATUSES")
public class Status {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id_s")
private int id_s;
@Column(name = "name")
private String name;
@OneToMany(mappedBy = "status")
List<Order> orders;
public Status() {}
public int getId_s() {
return id_s;
}
public void setId_s(int id_s) {
this.id_s = id_s;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "Status:" + name;
}
}

我尝试了各种选项,并在这里阅读了几乎所有关于它的帖子,但它们是关于plusframework,xml映射或其他。
你能帮忙吗?

当数据库中存在参照完整性问题时,我已经看到过此消息(这并不是您真正想到的第一件事)。在我的情况下,问题是集合中的项引用了另一个表中已被删除的行。
如果可能,最简单的方法是确保使用参考索引设置数据库,以确保不会发生这种情况。

当您致电session
时,问题是休眠collection
在同一session
内检测到相同的update()
两次。
<强>解决方案:强>
确保您的实体中没有重复的setter和getter,而不是使用update()
,而只使用merge()
。

我确定了问题的根源。这是所有事物的身份。最初我在Hibernate's
档import.sql
:
INSERT INTO roles (id_r,"name") VALUES (1,'user');
INSERT INTO roles (id_r,"name") VALUES (11,'sell');
INSERT INTO roles (id_r,"name") VALUES (111,'admin');
INSERT INTO salepoints (id_sp,"name") VALUES (0,'HQ');
INSERT INTO salepoints (id_sp,"name") VALUES (1,'INTERNET');
INSERT INTO users (...,id) VALUES (...,0);
两个SalesPoint
个ID都被roles
(INTERNET)和新的初始user
(HQ)复制。更改为:
INSERT INTO roles (id_r,"name") VALUES (1,'user');
INSERT INTO roles (id_r,"name") VALUES (11,'sell');
INSERT INTO roles (id_r,"name") VALUES (111,'admin');
INSERT INTO salepoints (id_sp,"name") VALUES (5,'HQ');
INSERT INTO salepoints (id_sp,"name") VALUES (10,'INTERNET');
INSERT INTO users (...,id) VALUES (...,50);
SELECT setval('public.hibernate_sequence', 200, true);
//It will work with every value
//above the maximum from the id inserted.
像魅力一样工作。

在我的情况下,a在A和B之间存在许多ToMany实现,并且在A的equals()方法中,A.b和otherA.b之间的比较引起了这种情况。我确定了原因,但我对此并不了解。
答案 4 :(得分:0)
在我的案例中,我正在删除和更新同一事务中的对象。我先删除对象,然后更新。这导致了例外。 为了解决异常,我只是先更改了更新顺序,然后删除了未引用的对象。
