从特定模式中删除行时出现此错误:

即使调用了带有正确参数的 delete 方法,它仍然在运行导致数据违规问题的插入查询。
这是模型:
@Entity
@Table(uniqueConstraints={@UniqueConstraint(columnNames={"userId", "journalId"})})
public class Subscription {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@Version
private Integer version;
private Integer userId;
private Integer journalId;
public void setId(Integer id) {
this.id = id;
}
public Integer getId() {
return this.id;
}
public void setVersion(Integer version) {
this.version = version;
}
public Integer getVersion() {
return this.version;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public Integer getUserId() {
return this.userId;
}
public void setJournalId(Integer journalId) {
this.journalId = journalId;
}
public Integer getJournalId() {
return this.journalId;
}
}
这里是删除方法被调用的地方:
@Override
public void unsubscribeJournalForSubscriber(Journal journal, Account subscriber) {
Subscription subscription = new Subscription();
subscription.setJournalId(journal.getId());
subscription.setUserId(subscriber.getId());
this.subscriptionRepository.delete(subscription);
}
最佳答案
如果您想在不使用主键的情况下删除记录,请为此创建一个查询。在名为“SubscriptionRepository”的方法中创建一个方法
@修改中
@Query("从 Subscription 中删除 s.role.userId = ?1 and s.journalId = ?2")
deleteByUserIdJournalId(Integer userId,Integer journalId)
然后使用该方法删除您的记录。
