Hibernate事务未成功启动

hibernate

考虑以下简单的Hibernate场景:

session = getHibernateSession();
tx = session.beginTransaction();
SomeObject o = (SomeObject) session.get(SomeObject.class, objectId);
tx.commit();

此代码产生以下异常:

org.hibernate.TransactionException: Transaction not successfully started
    at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:100)
    at com.bigco.package.Clazz.getSomeData(Clazz.java:1234)

这是怎么回事?

好吧,看来一旦我们达到要求tx.commit(),交易就已经提交了。我唯一的猜测是Hibernate get()在访问对象时已经提交了事务。

解决方法很简单:

// commit only if tx still hasn't been committed yet (by hibernate)
if (!tx.wasCommitted())
    tx.commit();
