hibernate checkbox 根据id批量删除

<td >
<label class="i-checks">
<input type="checkbox" name="subBox" value="${list.id}">
<i></i>
</label>
</td>

<script type="text/javascript"> $(function() { $("#del-vod").click(function() { var ids= new Array(); var i=0; $("input:checkbox[name='subBox']:checked").each(function() { // 遍历name=test的多选框
ids[i++]=$(this).val(); // 每一个被选中项的值
}); if(ids=="") { alert("请至少选择一条记录"); return false; } if(window.confirm("确定删除吗？")) { window.location.href="deletes.do?ids="+ids; } }); }) </script>

 

dao层

//该方法效率慢，生成多条HQL

public void deletes(List<Integer> idList) { for (Integer id : idList) { Timeliftinfo timeinfo = (Timeliftinfo)getSession().load(Timeliftinfo.class, id); if(timeinfo != null) { getSession().delete(timeinfo); } } }

 

//优化后，只生成一条HQL

 

public void deletes(List<Integer> idList) { String hql = ""; for (int i = 0; i < idList.size(); i++) { if(i==0) { hql = "id="+idList.get(i); } else { hql =hql + " or id="+idList.get(i); } Session session= this.getSession(); Query q= session.createQuery("delete from Timeliftinfo where "+hql); q.executeUpdate(); } }

 

 

 

Service调用接口，action

//批量删除
@RequestMapping(value = "/vms/media_main/deletes.do") public ModelAndView deletes(String ids) { String[] id = ids.split(","); List<Integer> list = new ArrayList<Integer>(); for (int i=0;i<id.length;i++){ int a = new Integer(id[i]); list.add(a); } timeService.deletes(list); Map<String,Object> data = new HashMap<String, Object>(); data.put("message","删除成功"); data.put("url","SY_timeliftinfoList.do"); return new ModelAndView("vms/media_main/save",data); }
