我刚刚才开始学习框架的东西
所以想把spring留到掌握hibernate后来学习
谢谢楼上建议
----------------解决方案--------------------------------------------------------
private Transaction tx=session.beginTransaction();
public List<LUser> getByName(String username) {
String sql="from LUser user where username=:name";
Query query=session.createQuery(sql);
query.setParameter("name", username);
return query.list();
是不是缺少了个commit() ?
----------------解决方案--------------------------------------------------------
这个方法不需要commit();
如果有空你可以仔细看看我的代码
谢谢

private Transaction tx=session.beginTransaction();
public List<LUser> getByName(String username) {
String sql="from LUser user where username=:name";
try{
Query query=session.createQuery(sql);
query.setParameter("name", username);
return query.list();
tx.commit();
}catch(HibernateException e)
{
e.printStackTrace();
rollback();
}
