本文主要介绍一下 Vue + SpringBoot 中如何实现一个分页列表数据。

1、效果展示

2、VUE代码

VUE之视图定义

<el-row>
            <el-table
                :data="tableData"
                style="width: 100%">
                <el-table-column
                    v-for="(data,index) in tableHeader"
                    :key="index"
                    :prop="data.prop"
                    :label="data.label"
                    :min-width="data['min-width']"
                    :align="data.align">
                </el-table-column>
                <el-table-column
                    label="操作"
                    min-width="240">
                    <template slot-scope="scope">
                        <el-button type="success" size="mini" @click="toRecharge(scope)">充值</el-button>
                        <el-button size="mini" @click="toView(scope)">查看</el-button>
                        <el-button type="primary" size="mini" @click="toEdit(scope)">修改</el-button>
                        <el-button type="danger" size="mini" @click="deleteCard(scope)">删除</el-button>
                    </template>
                </el-table-column>
            </el-table>
            <br>
            <el-pagination
                @size-change="handleSizeChange"
                @current-change="handleCurrentChange"
                :current-page="pagination.pageIndex"
                :page-sizes="[5, 10, 20, 30, 40]"
                :page-size=pagination.pageSize
                layout="total, sizes, prev, pager, next, jumper"
                :total=pagination.total>
            </el-pagination>
</el-row>

重点说明：

数据类型定义:

tableData：定义后台数据模型定义。

tableHeader:定义表格与后台数据绑定关系。

pagination：定义分页数据模型，主要包含（pageIndex:当前页，pageSize:页大小, total:总记录数）

方法定义:

handleSizeChange：更新页大小

handleCurrentChange:更新当前页

VUE之模型定义(data)

tableData: [],
        pagination: {
            pageIndex: 1,
            pageSize: 10,
            total: 0,
        },
        tableHeader: [
                    {
                        prop: 'sid',
                        label: '编号',
                        align: 'left'
                    },
                    {
                        prop: 'password',
                        label: '密码',
                        align: 'left'
                    },
                    {
                        prop: 'state',
                        label: '状态',
                        align: 'left'
                    },
                    {
                        prop: 'money',
                        label: '金额',
                        align: 'left'
                    },
                    {
                        prop: 'studentSid',
                        label: '学生SID',
                        align: 'left'
                    }
 
                ]

VUE之数据初始化

VUE 方法定义：请求后台数据接口加载相关数据(method)

init () {
        var self = this
         this.$axios({
            method:'post',
            url:'/card/findPage',
            data:{"page":this.pagination.pageIndex,"limit":this.pagination.pageSize},
            headers:{
                'Content-Type':'application/json;charset=utf-8'      //改这里就好了
          }
        }).then(res => {
            console.log(res);
           self.pagination.total = res.data.data.total_count;
           self.tableData = res.data.data.list;
 
        })
          .catch(function (error) {
            console.log(error)
          })
        },
        handleSizeChange(val) {
                this.pagination.pageSize = val;
                this.pagination.pageIndex = 1;
                this.init();
        },
        handleCurrentChange(val) {
                this.pagination.pageIndex = val;
                this.init();
        },

VUE 声明周期函数定义：调用VUE的方法定义，完成数据初始化过程.

在VUE声明周期函数mounted ()中，调用init ,完成数据初始化过程。

mounted: function () {
      this.init()
 }

3、SpringBoot 代码
