Hibernate 删除记录惨遭失败

【中文标题】Hibernate 删除记录惨遭失败【英文标题】：Hibernate delete record miserably fails 【发布时间】：2013-11-27 06:43:05 【问题描述】：我一直在用头撞墙。 session.delete(object) 可悲地无法向我显示这些消息。
当我复制并粘贴休眠生成的删除sql，并在SQLDeveloper中运行该sql时，它运行得很好并删除了记录，但它在休眠中不起作用。 奇怪... 我猜可能是因为“select - before - update”，所以我将 select-before-update="false" 放在我的 hbm 文件中，但我看到它仍然在删除之前发出了 select 语句。 我做错了什么？

编辑 我刚试过这个。
Session session = sessionFactory.getCurrentSession();
Mea_class_no found = readMeaClassNo(target);
System.out.println("getCurrentLockMode ? " + session.getCurrentLockMode(found));
session.delete(found);
System.out.println("isDirty ? " + session.isDirty());
我在控制台中看到了这一点。
getCurrentLockMode ? READ
isDirty ? true
但我不知道从这里做什么。
EDIT2 令我惊讶的是，添加
optimistic-lock="dirty"
到我的 hbm 文件，成功删除了一条记录，但它发出了一个奇怪的删除语句！

【问题讨论】：
看看***.com/a/11736653/1651233 @whoAmI，堆栈跟踪没有提到 StaleStateException。 stacktrace（这里和那里）都有这一行： org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0];实际行数：0；预计：1 【参考方案1】：检查数据库模式中是否存在级联，导致每次从JUNC_ITEM_HISTORY 中删除引用记录时都会删除记录MEA_CLASS_NO。或者在 SQLDeveloper 中尝试在一个事务中运行两个查询。如果级联存在，则应将其从数据库中删除并在 Hibernate 级别中声明。
【讨论】：
感谢 Alexey，但为了使问题更容易解决，我删除了关联。尽管如此，任何更新或删除语句都会失败。 你删除了什么？外键？它是否包含 ON DELETE CASCADE？您是否尝试过在 SQLDeveloper 中执行这两个查询？【参考方案2】：原来，它没有更新或删除的原因是类型不匹配。
由于某种奇怪的原因，表设计器将数字列声明为 varchar(1) 我正在将该 varchar 列映射到 POJO int 字段。
将字段类型更改为字符串后，问题就消失了。
