我选择了一个遗留项目，正在为他们编写测试......但测试似乎因违反约束而失败，无法插入汽车......

两个班...

一个类具有以下映射：

@LazyCollection(LazyCollectionOption.FALSE)
@OneToMany(targetEntity=Cars.class, cascade=CascadeType.ALL, mappedBy="factory")
public List<Cars> getCars() {
    return cars;
}

多方面的课程有以下课程：

@OneToOne(targetEntity=Factory.class, optional=false)
@JoinColumn(name="factory_id")
public Factory getFactory() {
    return factory;
}

这在我的测试中失败了，使用 hsql .. 但是当完全部署战争应用程序时在 SQL 服务器中工作正常......我自己没有测试过，但被告知可以。

我认为这与关系的映射有关...

我的堆栈跟踪：

更改为 manyToOne .. 它会起作用。映射不正确。
