本文主要为大家分享一篇Vue.js如何实现真分页的问题，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧。

思路：

前端在初始化过程中，第一步先请求总的条数，然后，再请求第一页数据，然后根据点击翻页事件根据请求页码用ajax（axios和qs）去后台取得数据。

过程：

页码配置项：

pagerData:{
                    data:[],
                    page:{
                    	//分页数
                        arrPageSize:[10,20,30,40],
                        //分页大小
                        pageSize:10,
                        //总分页数
                        pageCount:1,
                        //当前页面
                        pageCurrent:1,
                        //总数
                        totalCount:80
                    }
                },

服务Impl：

	@Override
	public List getPageList(int startpage, int endpage) throws IOException {
		// TODO Auto-generated method stub
		init();
		List list = aMapper.selectByPage(startpage,endpage,null);
		return list;
	}

	@Override
	public Integer getCount() throws IOException {
		// TODO Auto-generated method stub
		init();
		Integer count = (int) aMapper.countByExample(null);
		return count;
	}

1请求总数

vue.js（JavaScript）代码：

created(){
			//请求总页数
			this.$axios.post("http://localhost:8088/Web/ListServlet",
					{params:{
						init:true
					}}
				,
				{
					headers:{'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}
				}
				)
			.then(res=>{
				console.log(JSON.stringify(res.data));
				var object = eval(res.data);
				var totalNum = object["count"];
				console.log("totalNum:" + totalNum);
				this.pagerData.page.totalCount = totalNum;
			});}

后台代码（Java）：

String queryString = readRequest(request);
		
		JSONObject object = null;
		object = JSONObject.fromObject(queryString);
		JSONObject params = (JSONObject) object.get("params");
		//判断是是初始化过程
		if((params.getString("init")).equals("true")) {
			Integer count = service.getCount();
			PrintWriter out = response.getWriter();
			JSONObject result = new JSONObject();
			result.put("count", count);
			logger.info(result.toString());
			out.write(result.toString());
			out.close();
			return;
		}
		logger.info(params.get("startpage"));
		logger.info(params.get("endpage"));
		//判断不是初始化过程
		if((params.getString("init")).equals("false")) {
			PrintWriter out = response.getWriter();
			List list = service.getPageList(Integer.parseInt((params.getString("startpage"))),
					Integer.parseInt((params.getString("endpage"))));
			JSONArray array = JSONArray.fromObject(list);
			out.write(array.toString());
			out.close();
			return;
		}
public String readRequest(HttpServletRequest request) throws IOException {
		BufferedReader reader = new BufferedReader(new InputStreamReader(request.getInputStream(),"UTF-8"));
		String temp = "";
		String s = "";
		while((temp = reader.readLine()) != null)
		{
			s = s + temp;
		}
		return s;
	}

2请求首页和后续页码

vue.js（JavaScript）代码：

//请求首页 1-10
			this.$axios.post("http://localhost:8088/Web/ListServlet",
				
					{params:{
						init:false,
						startpage:1,
						endpage:10
					}}
				,
				{
					headers:{'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}
				}
				)
			.then(res=>{
				console.log(JSON.stringify(res.data));
				var object = eval(res.data);
				var totalNum = object["count"];
				console.log("totalNum:" + totalNum);
				for(var i = 0; i < res.data.length; i++){
					//console.log("res.data[i] is " + i + "\n " + JSON.stringify(res.data[i]));
					var object = eval(res.data[i]);
					object.index = i+1;
					totalNum ++;
					if(i<=10){	//初始化获取数据的过程中，将前10个默认加入分页data
						this.pagerData.data.push(object);
						}
					}
				//this.pagerData.page.totalCount = totalNum;
			});
			this.loading = false;
			
			
		}

翻页（change）：

this.$axios.post('http://localhost:8088/Web/ListServlet',
            		{params:{
            			init:false,
				startpage:((curpage-1)*this.pagerData.page.pageSize +1),
				endpage:curpage*this.pagerData.page.pageSize
            		}},
            		{
            			headers:{'Content-Type':'application/x-www-form-urlencoded;charset=utf-8'}
            		}
            	).then(res=>{
					console.log(JSON.stringify(res.data));
					var object = eval(res.data);
					for(var i = 0; i < res.data.length; i++){
						//console.log("res.data[i] is " + i + "\n " + JSON.stringify(res.data[i]));
						var object = eval(res.data[i]);
						object.index = (curpage-1)*this.pagerData.page.pageSize +1 + i;
						if(i<=this.pagerData.page.pageSize){
							this.pagerData.data.push(object);
							}
						}
					//this.pagerData.page.totalCount = totalNum;
				})

后台代码（Java）：

//判断不是初始化过程
		if((params.getString("init")).equals("false")) {
			PrintWriter out = response.getWriter();
			List list = service.getPageList(Integer.parseInt((params.getString("startpage"))),
					Integer.parseInt((params.getString("endpage"))));
			JSONArray array = JSONArray.fromObject(list);
			//logger.info(array.get(1).toString());
			out.write(array.toString());
			out.close();
			return;
		}
