HibernateTemplate删除数据小结 删除
DAO代码：
public void delete(Integer lid) {
       log.debug(“deleting Login instance”);
       try {
        Login login=(Login)this.getHibernateTemplate().load(Login.class,lid);
           getHibernateTemplate().delete(login);
           log.debug(“delete successful”);
       } catch (RuntimeException re) {
           log.error(“delete failed”, re);
           throw re;
       }
   }

调用DAO：
Integer selid = Integer.valueOf(request.getParameter(“select”));
loginDAO.delete(selid);

批量删除
需要注意的是in后面跟的是字符串，如果不是会提示org.hibernate.QueryException: unexpected char: ‘;’的出错
DAO代码：
public void delete(String[] lid) {
   String[] ids = lid;
        String str=”";
        for(int i=0;i<ids.length;i++){
            str+=”‘”+ids[i]+”‘”;
            if(i!=(ids.length-1))
                str+=”,”;
            }
 List list   =   this.getHibernateTemplate().find(“from Login where id in (“+str+”)”);
 if(list.size()>0){  
    this.getHibernateTemplate().deleteAll(list);
    }
}

或者可以这样写：
 public void batchDelete(String[] lid) {
     String[] ids = lid;
          for(int i=0;i<ids.length;i++){
              log.debug(“deleting Login instance”);
           try {
            TPhotoclass tTPhotoclass=(TPhotoclass)this.getHibernateTemplate().load(TPhotoclass.class,Long.parseLong(ids[i]));
               getHibernateTemplate().delete(tTPhotoclass);
               log.debug(“delete successful”);
           } catch (RuntimeException re) {
               log.error(“delete failed”, re);
               throw re;
           }
              }
  }

调用DAO：
String[] lid = request.getParameterValues(“select”);
loginDAO.delete(lid);
