使用Bootstrap4 + Vue2实现分页查询的示例代码

写在前面

工程为前后端分离设计,使用Nginx为前端资源服务器,同时实现后台服务的反向代理。后台为Java Web工程,使用Tomcat部署服务。

  1. 前端框架:Bootstrap4,Vue.js2
  2. 后台框架:spring boot,spring data JPA
  3. 开发工具:IntelliJ IDEA,Maven

实现效果:

会员信息

如何使用Bootstrap+Vue来实现动态table,数据的新增删除等操作,请查看使用Bootstrap + Vue.js实现表格的动态展示、新增和删除 。交代完毕,本文主题开始。

一、使用Bootstrap搭建表格

表格区

<div class="row">

<table class="table table-hover table-striped table-bordered table-sm">

<thead class="">

<tr>

<th><input type="checkbox"></th>

<th>序号</th>

<th>会员号</th>

<th>姓名</th>

<th>手机号</th>

<th>办公电话</th>

<th>邮箱地址</th>

<th>状态</th>

</tr>

</thead>

<tbody>

<tr v-for="(user,index) in userList">

<td><input type="checkbox" :value="index" v-model="checkedRows"></td>

<td>{{pageNow*10 + index+1}}</td>

<td>{{user.id}}</td>

<td>{{user.username}}</td>

<td>{{user.mobile}}</td>

<td>{{user.officetel}}</td>

<td>{{user.email}}</td>

<td v-if="user.disenable == 0">正常</td>

<td v-else>注销</td>

</tr>

</tbody>

</table>

</div>

分页区

<div class="row mx-auto">

<ul class="nav justify-content-center pagination-sm">

<li class="page-item">

<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="page-link"><i class="fa fa-fast-backward" @click="switchToPage(0)"> </i></a>

</li>

<li class="page-item">

<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="page-link"><i class="fa fa-backward" @click="switchToPage(pageNow-1)"></i></a>

</li>

<li class="page-item" v-for="n in totalPages" :class="{active:n==pageNow+1}">

<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="switchToPage(n-1)" class="page-link">{{n}}</a>

</li>

<li class="page-item">

<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="page-link"><i class="fa fa-forward" @click="switchToPage(pageNow+1)"></i></a>

</li>

<li class="page-item">

<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="page-link"><i class="fa fa-fast-forward" @click="switchToPage(totalPages-1)"></i></a>

</li>

</ul>

</div>

二、初始化Vue对象及数据

创建Vue对象

var vueApp = new Vue({

el:"#vueApp",

data:{

userList:[],

perPage:10,

pageNow:0,

totalPages:0,

checkedRows:[]

},

methods:{

switchToPage:function (pageNo) {

if (pageNo < 0 || pageNo >= this.totalPages){

return false;

}

getUserByPage(pageNo);

}

}

});

初始化数据

function getUserByPage(pageNow) {

$.ajax({

url:"/user/"+pageNow,

success:function (datas) {

vueApp.userList = datas.content;

vueApp.totalPages = datas.totalPages;

vueApp.pageNow = pageNow;

},

error:function (res) {

console.log(res);

}

});

}

完整js代码:

<script>

var vueApp = new Vue({

el:"#vueApp",

data:{

userList:[],

perPage:10,

pageNow:0,

totalPages:0,

checkedRows:[]

},

methods:{

switchToPage:function (pageNo) {

if (pageNo < 0 || pageNo >= this.totalPages){

return false;

}

getUserByPage(pageNo);

}

}

});

getUserByPage(0);

function getUserByPage(pageNow) {

$.ajax({

url:"/user/"+pageNow,

success:function (datas) {

vueApp.userList = datas.content;

vueApp.totalPages = datas.totalPages;

vueApp.pageNow = pageNow;

},

error:function (res) {

console.log(res);

}

});

}

</script>

三、使用JPA实现分页查询

controller接收请求

/**

* 用户相关请求控制器

* @author louie

* @date 2017-12-19

*/

@RestController

@RequestMapping("/user")

public class UserController {

@Autowired

private UserService userService;

/**

* 分页获取用户

* @param pageNow 当前页码

* @return 分页用户数据

*/

@RequestMapping("/{pageNow}")

public Page<User> findByPage(@PathVariable Integer pageNow){

return userService.findUserPaging(pageNow);

}

}

JPA分页查询

@Service

public class UserServiceImpl implements UserService {

@Value("${self.louie.per-page}")

private Integer perPage;

@Autowired

private UserRepository userRepository;

@Override

public Page<User> findUserPaging(Integer pageNow) {

Pageable pageable = new PageRequest(pageNow,perPage,Sort.Direction.DESC,"id");

return userRepository.findAll(pageable);

}

}

好了,至此功能完成,工程代码已在GitHub中分享,您可以 点击查看或下载 ,拥抱开源,共享让世界更美好。
