java - 当我尝试将多个数据插入子表时出现错误无法执行 JDBC 批量更新

Question

我创建了两个类，父类是Credit，子类是Debit。在贷方类中，有六个字段可用，而在借方实体中，只有两个字段是动态添加的 - 金额和描述与 hibernate 的一对多关系。

当我尝试将数据插入两个表时，会发生此错误:

Could not execute JDBC batch update; SQL [insert into debit (amount, description, did) values (?, ?, ?)]; constraint [cid]; nested exception is org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update

Answer 1

在你的类(class)借方

在您的类 CreditServiceImpl 函数 addCreditDebit 中，您执行以下操作:

credit.setDebit(debList);
creditDao.addCreditDebit(credit);

因此，您设置属性借方，然后更新或更新您的实体贷方。

但是在你的类借记中有一行:

@JoinColumn(name="cid", insertable=false, updatable=false, nullable=false)
private Credit credit;

尝试删除 insertable=false 和 updatable=false
