spring管理hibernate事务报异常--Transaction not successfully started解决方法

通过spring管理配置了事务管理，但是在执行过程中还是出现了异常：
Transaction not successfully started

以下三段代码均报了该异常。

1.
publicvoidupdateProcInstObj(TaProcInsttaProcInstObj_from2)throwsException{
Stringhql="updateTaProcInstsetinststate=?,runtimes=?,completetime=?whereprocinstid=?";
this.getSession.createQuery(hql)
.setString(0,taProcInstObj_from2.getInststate())
.setInteger(1,taProcInstObj_from2.getRuntimes().intValue())
.setString(2,taProcInstObj_from2.getCompletetime())
.setString(3,taProcInstObj_from2.getProcinstid())
.executeUpdate();
}

2.
publicvoidupdateProcInstObj(TaProcInsttaProcInstObj_from2)throwsException{
TransActiontransAction=this.getSession().getTransAction();
transAction.begin();
Stringhql="updateTaProcInstsetinststate=?,runtimes=?,completetime=?whereprocinstid=?";
this.getSession.createQuery(hql)
.setString(0,taProcInstObj_from2.getInststate())
.setInteger(1,taProcInstObj_from2.getRuntimes().intValue())
.setString(2,taProcInstObj_from2.getCompletetime())
.setString(3,taProcInstObj_from2.getProcinstid())
.executeUpdate();
transAction.commit();
}

3.
publicvoidupdateProcInstObj(TaProcInsttaProcInstObj_from2)throwsException{
TransActiontransAction=this.getSession().beginTransAction();
Stringhql="updateTaProcInstsetinststate=?,runtimes=?,completetime=?whereprocinstid=?";
this.getSession.createQuery(hql)
.setString(0,taProcInstObj_from2.getInststate())
.setInteger(1,taProcInstObj_from2.getRuntimes().intValue())
.setString(2,taProcInstObj_from2.getCompletetime())
.setString(3,taProcInstObj_from2.getProcinstid())
.executeUpdate();
transAction.commit();
}

修改为如下的方式则可以解决此问题：

publicvoidupdateProcInstObj(TaProcInsttaProcInstObj_from2)throwsException{
Sessionsession=this.getSession();
Stringhql="updateTaProcInstsetinststate=?,runtimes=?,completetime=?whereprocinstid=?";
session.createQuery(hql)
.setString(0,taProcInstObj_from2.getInststate())
.setInteger(1,taProcInstObj_from2.getRuntimes().intValue())
.setString(2,taProcInstObj_from2.getCompletetime())
.setString(3,taProcInstObj_from2.getProcinstid())
.executeUpdate();
session.flush();
session.clear();
}
