Question

Caused by: java.sql.SQLException: Result set already closed

代码如下：
//======================================================
User user= (User)getService().load(User.class, "admin");
//修改用户名
user.setUsername("temp");
//更新数据库
getService().update(user);
//=========================================================
报错：
org.hibernate.exception.GenericJDBCException: could not load an entity
Caused by: java.sql.SQLException: Result set already closed

但是，如果在debug状态下，我把鼠标移到user.setUsername("temp");的user上之后再执行下去就没有此错了

这有可能是什么原因
org.hibernate.exception.GenericJDBCException: could not load an entity: [domain.User#admin]

at org.hibernate.loader.entity.EntityLoader.loadByUniqueKey(EntityLoader.java:85)
数据是存在的

Answer 1

Result set already closed
Result已经关闭了
要想操作成功，则要打开Result

Answer 2

[domain.User#admin] 没有admin这条记录？

Answer 3

确认下你的Hibernate连接是否在执行Update前被关闭了?
