java ssh项目更新问题，先查询数据，然后进行更新操作，为什么保存不成功？下面有代码和控制台的一些信息

public void changeBidpToPool() {
String ids = Struts2Utils.getParameter("ids");
String idps[] = ids.split(",");
Criterion criterion = Restrictions.in("id", idps);
@SuppressWarnings("unchecked")
List<BidProject> bidPools = (List<BidProject>) getObjectService()
.findByCriteria(BidProject.class, criterion);
for (BidProject bidProject : bidPools) {
bidProject.setTempType(Short.valueOf("1"));
}
getObjectService().batchSaveOrUpdate(bidPools);
}

大家帮忙看一下该怎么解决？

Answer 1

不知道你项目使用ssh框架没 应该是数据没持久化到数据库中哦就是事物没提交哦
如果使用了ssh框架那么看下spring配置文件是否配置了事物提交以及方法名是否命名错误了

追问

事物提交是怎么配置的？

我这样配置的不知道有错没？

追答

你看你那个spring 中配置了以update* 就是以update开头命名的方法才会提交事物哦你把你的方法名改成 update。。。的就可以了

追问

我现在改了，但是不行，之后我用一条数据更新，用get查询，之后更新可以
public void updateBidpToPool() {
String ids = Struts2Utils.getParameter("ids");
BidProject bidProject=(BidProject) getObjectService().getObj(BidProject.class, ids);
bidProject.setTempType(Short.valueOf("1"));
getObjectService().updateObj(bidProject);
System.out.println("------------------");
}

追答

你的实现类实现hibernateDaoSupport接口没？

追问

实现了HibernateDaoImpl extends HibernateDaoSupport
get查询方法
@Override
public Object get(Class cls, Serializable id) {
return getHibernateTemplate().get(cls, id);
}
另一个查询方法

见下一个追问
您回一句话，我才能提交下一个追问

Answer 2

如果不是批量更新，修改一条更新一条也出错吗

追问

嗯，就是没反应了，后台也不报错，前台卡死到哪了

Answer 3

你这里循环更新肯定只能更新最后一条！是吧？
