我有一个Spring MVC项目，带有Hibernate注释实体映射。到目前为止，数据库创建得很好，保存新对象没有问题。直到我添加了一个新的实体类。

当我尝试保存User更改了日期字段（last_login）的 a 时，会发生错误，如下所示：

 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);

在哪里：

@Override
public boolean update(User user) {
    try {
        session().update(user);
    } catch (Exception e) {
        return false;
    }
    return true;
}

我尝试将级联添加到关系中，尝试不使用它们（它们工作正常，没有类）。

用户.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
}

状态.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 映射或其他的。

你能帮我吗？

当数据库中存在引用完整性问题时（这并不是您真正想到的第一件事），我已经看到了此消息。就我而言，问题是集合中的项目引用了另一个表中已删除的行。

如果可能的话，确保您的数据库设置有引用索引以确保不会发生这种情况可能是最简单的。

问题：

问题是hibernate在你调用时session检测到相同的collection两次。sessionupdate()

解决方案：

确保您的实体中没有重复的 setter 和 getter，而不是update()仅使用 use merge()。

我查明了问题的根源。它是所有事物的身份。最初我在Hibernate's文件中有这个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SalesPointid 都被roles(INTERNET) 和新的初始user(HQ) 配音。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 manyToMany 关系，并且在 A 的 equals() 方法中，Ab 和 otherA.b 之间的比较导致了这种情况。我确定了原因，但我不明白。

在我的案例中，我在同一个事务中删除和更新对象。我先删除对象然后更新。这导致了异常。为了解决异常，我只是更改了先更新然后删除未引用对象的顺序。
