第77讲用户管理功能实现

用户管理功能实现
前端：
views/user/index.vue

<template>
  <el-card>
    <el-row :gutter="20" class="header">
      <el-col :span="7">
        <el-input placeholder="请输入用户昵称..." clearable v-model="queryForm.query"></el-input>
      </el-col>
      <el-button type="button" :icon="Search" @click="initUserList">搜索</el-button>
    </el-row>
    <el-table :data="tableData" stripe style="width: 100%">
      <el-table-column prop="id" label="#ID" width="80" />
      <el-table-column prop="nickName" label="用户昵称" width="200" />
      <el-table-column prop="avatarUrl" label="头像" width="200">
        <template v-slot="scope">
          <img :src="scope.row.avatarUrl" width="50" height="50"/>
        </template>
      </el-table-column>
      <el-table-column prop="openid" label="openID" />
      <el-table-column prop="registerDate" label="注册日期" width="200"/>
      <el-table-column prop="lastLoginDate" label="最后登录日期" width="200"/>
    </el-table>
    <el-pagination
        v-model:currentPage="queryForm.pageNum"
        v-model:page-size="queryForm.pageSize"
        :page-sizes="[10, 20, 30, 40,50]"
        layout="total, sizes, prev, pager, next, jumper"
        :total="total"
        @size-change="handleSizeChange"
        @current-change="handleCurrentChange"
    />
  </el-card>
</template>

<script setup>
  import {Search} from '@element-plus/icons-vue'
  import { ref } from 'vue'
  import axios from "@/util/axios";

  const queryForm=ref({
    query:'',
    pageNum:1,
    pageSize:10
  })

  const total=ref(0)


  const tableData =ref([])

  const initUserList=async()=>{
    const res=await axios.post("admin/user/list",queryForm.value);
    tableData.value=res.data.userList;
    total.value=res.data.total;
  }

  initUserList();

  const handleSizeChange = (pageSize) => {
    queryForm.value.pageNum=1;
    queryForm.value.pageSize=pageSize;
    initUserList();
  }
  const handleCurrentChange = (pageNum) => {
    queryForm.value.pageNum=pageNum;
    initUserList();
  }



</script>

<style lang="scss" scoped>

.header{
  padding-bottom: 16px;
  box-sizing: border-box;
}

.el-pagination{
  padding-top: 15px;
  box-sizing: border-box;
}


</style>

后端：

@RestController
@RequestMapping("/admin/user")
public class AdminUserController {

    @Autowired
    private IWxUserInfoService wxUserInfoService;

    /**
     * 根据条件分页查询用户信息
     * @param pageBean
     * @return
     */
    @RequestMapping("/list")
    public R list(@RequestBody PageBean pageBean){
        System.out.println(pageBean);
        String query=pageBean.getQuery().trim();
        Page<WxUserInfo> page=new Page<>(pageBean.getPageNum(),pageBean.getPageSize());
        Page<WxUserInfo> pageResult = wxUserInfoService.page(page, new QueryWrapper<WxUserInfo>().like(StringUtil.isNotEmpty(query),"nickName", query));
        Map<String,Object> map=new HashMap<>();
        map.put("userList",pageResult.getRecords());
        map.put("total",pageResult.getTotal());
        return R.ok(map);
