Java 提交期间的休眠异常

我们正在使用Spring2.5.6及其附带的Hibernate

作为我们架构的一部分，我们有一个服务和一个管理器。该服务调用经理来提供一个工作单元。我们在管理器周围放置一个AOP拦截器来管理事务

在我们的例子中，经理创建一个图像和一个注释，将该图像链接到一个人，然后返回到服务。这些都是全新的功能

运行此命令时，我得到以下堆栈跟踪：

当我搜索错误时，我发现了很多关于空值查询的条目。问题是我已经做了插入，效果很好。它在提交期间抛出此异常

image和note都是我过去使用过的现有字段。我最近在note to image上添加了一个链接，以便便笺可以引用图像

就因为有错误信息，我对这张图片产生了怀疑。以下是图像上图像数据字段的定义：

  @Column( name = "IMAGE_DATA" )
  @Lob()
  private byte[ ] imageData;

---

如果您能给我一些建议，我将不胜感激。

答案的关键在stacktrace的下半部分：

ORA-00932: inconsistent datatypes: expected NUMBER got BINARY

很难说这是关于哪个字段的，但由于您使用的是图像，因此您为该类/字段配置持久性的方式可能有问题

也许您应该通过使用注释提示Hibernate如何存储字段

@Lob(type = LobType.BLOB)

---

问题最终涉及到缺少注释

我刚刚在note条目中添加了一个图像，并将其设置为指向图像的UUID，但没有使用@OneToOne。因此，它似乎试图将图像数据存储在UUID的字段中

---

我添加了@OneToOne，问题就消失了。Nathan说的也很正确，在提交之前它实际上是不会被插入的。为了找到问题，我将这些插入移到事务之外，以便立即插入。这有助于我追踪问题。

我更改了最后一部分，按照您建议的思路提供了更多信息。请让我知道。记住Hibernate在必须执行任何插入之前（在提交或会话刷新时）不会执行任何插入。你好，老朋友。我明白了，回去工作吧。：）我对此感到奇怪。我会调查的。
