前端页面

<form>
        <input type="button" value="批量删除" class="btn" style="width: 50px; height: 25px; cursor: pointer; margin-bottom: 1px;" onclick="delete()"/>
        <table id="demo" lay-filter="test"></table>
    </form>
     
    <script type="text/javascript">
    function delete(){
    	var checkStatus = table.checkStatus('demo');
    	if(checkStatus.data.length==0){
    		parent.layer.msg('请先选择要删除的数据行！', {icon: 2});
    		return ;
    	}
    	var ids = "";
    	for(var i=0;i<checkStatus.data.length;i++){
    		ids += checkStatus.data[i].id+",";
    	}
    	parent.layer.msg('删除中...', {icon: 16,shade: 0.3,time:5000});
    	$.post('url',
                {'ids':ids},
                function(data){
    		        layer.closeAll('loading');
    		        if(data.code==1){
    			        parent.layer.msg('删除成功！', {icon: 1,time:2000,shade:0.2});
    			        location.reload(true);
    		        }else{
    			        parent.layer.msg('删除失败！', {icon: 2,time:3000,shade:0.2});
    		        }
    	        }
        );
    }
    </script>

后端

@RequestMapping(value="/delete",produces="application/json;charset=utf-8")
    @ResponseBody
    public Object delete(User user,Map<String, Object> map){
    	String ids = user.getIds();        //ids和id都存在于实体类User
    	String a[] = ids.split(",");
    	try{
    		for (int i = 0; i < a.length; i++) {
    			String id = a[i];
    			userService.deleteById(id);
    			map.put("code", 1);
    		}
    	}catch (Exception e) {
    		e.printStackTrace();
    		map.put("code", -1);
    	}
    	return JSON.toJSONString(map);
    		
    }
