final String name = userName;
         List list = (List)this.getHibernateTemplate().find("from User where userName=?",name );
          if(list!=null&&list.size()!=0{
          User user = (User)list.get(0);
          int id = user.getId();
          return id;}else{
return 0;}
}

Answer 1

上面if(list!=null&&list.size()!=0)这里少写了个")",加上

Answer 2

List list = getHibernateTemplate().find("from User where  userName=?",name);
晕死。我改成你这样写的了。但是执行的时候还是报空指针异常。错误提示为上面那句话出的错误。
我qq417223545 希望能给我指点一二。或者贴出来也行

Answer 3

问题找到：getHibernateTemplate()返回null
配置实在不知道哪里有问题
