效果图

前端：

<template>
  <div>
    <h2>用户列表</h2>
    <el-table style="width: 100%" stripe border highlight-current-row :data="userList" >
      <el-table-column align="center" prop="id"   label="员工编号" ></el-table-column>
      <el-table-column align="center" prop="name" label="员工姓名"></el-table-column>
      <el-table-column align="center" prop="sex"  label="员工性别"></el-table-column>
      <el-table-column align="center" prop="age"  label="员工年龄"></el-table-column>
      <el-table-column align="center" label="操作">
        <template slot-scope="scope">
          <el-button size="mini" @click="handleEdit(scope.row)">编辑</el-button>  <!--scope.row当前行的对象-->
          <el-button size="mini" type="danger" @click="handleDelete(scope.row)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>
    <div class="block">
      <el-pagination
        hide-on-single-page   当数据只有一页时,自动隐藏分页菜单
        @size-change="handleSizeChange"        当每页显示的数据数目发生改变生的动作,需要按新的pageSize查询数据
        @current-change="handleCurrentChange"  当改变当前页时产生的动作
        :current-page="pageNo"                 绑定当前页
        :page-sizes="[5, 10, 30, 50]"          显示pageSize的选项
        :page-size="pageSize"				  绑定当前页数
        layout="total, sizes, prev, pager, next, jumper"
        :total="totalCount">				  绑定当前总数
      </el-pagination>
    </div>

后端

@RestController
public class TestController {
    @Autowired
    UserServiceImpl userService;
    
    @RequestMapping("/getCount")
    public String getCount(){
        return Integer.toString(userService.getCount());
    }
    @RequestMapping("/getUserList")
