> 业务场景： 针对一个问题表单进行筛选，查询过滤后的数据，是一个基本的功能，而随着数据过多，前端表格设计时是需要有一个分页的功能，比如查询了有100条，那么我们设定一页10条，分成10页给业务看，那么这里后端接口就需要返回哪些东西： 问题总数量，当前分页，页大小，以及当前页的问题表单数据 接下来看看一个例子

**controller类：**

@RestController
    @RequestMapping(value = "/ProdProblemWarn", produces = {"application/json;charset=UTF-8"})
    @Validated
    public class ProdProblemWarnController {
    
        @Autowired(required=false) 
        private ProdProblemWarnDelegate delegate;      
    
    @RequestMapping(
        		value = "/getWarnPage", 
        		produces = { "application/json" }, 
        		method = RequestMethod.POST)
        public ResponseVo getWarnPage(@RequestBody ProdProblemWarnQueryParam queryParam) 
                throws ServiceException {
        	    
    		return delegate.getWarnPage(queryParam);
        }
    
    }

**请求参数类：ProdProblemWarnQueryParam**
