标的列表

一、后端实现

1、扩展实体对象

在Lend类中扩展以下字段

@ApiModelProperty(value = "其他参数")
@TableField(exist = false)
private Map<String,Object> param = new HashMap<>();

2、Controller

添加 AdminLendController

@Api(tags = "标的管理")
@RestController
@RequestMapping("/admin/core/lend")
@Slf4j
public class AdminLendController {

    @Resource
    private LendService lendService;

    @ApiOperation("标的列表")
    @GetMapping("/list")
    public R list() {
        List<Lend> lendList = lendService.selectList();
        return R.ok().data("list", lendList);
    }
}

3、Service

接口：LendService

List<Lend> selectList();

实现：LendServiceImpl

@Resource
private DictService dictService;

@Override
public List<Lend> selectList() {
    List<Lend> lendList = baseMapper.selectList(null);
    lendList.forEach(lend -> {
        String returnMethod = dictService.getNameByParentDictCodeAndValue("returnMethod", lend.getReturnMethod());
        String status = LendStatusEnum.getMsgByStatus(lend.getStatus());
        lend.getParam().put("returnMethod", returnMethod);
        lend.getParam().put("status", status);
    });
    return lendList;
}

二、前端

1、创建页面组件

创建 src/views/core/lend/list.vue

<template>
  <div class="app-container">
    标的列表
  </div>
</template>

<script>
export default {
  
}
</script>

创建 src/views/core/lend/detail.vue

<template>
  <div class="app-container">
    标的详情
  </div>
</template>

<script>
export default {
  
}
</script>

2、配置路由

src/router/index.js

{ path: '/core/lend', component: Layout, name: 'coreLend', meta: { title: '标的管理', icon: 'el-icon-s-flag' }, alwaysShow: true, children: [ { path: 'list', name: 'coreLendList', component: () => import('@/views/core/lend/list'), meta: { title: '标的列表' } }, { path: 'detail/:id', name: 'coreLendDetail', component: () => import('@/views/core/lend/detail'), meta: { title: '标的详情' }, hidden: true } ] },

3、定义api

创建 src/api/core/lend.js

import request from '@/utils/request'

export default {
  getList() {
    return request({
      url: `/admin/core/lend/list`,
      method: 'get'
    })
  }
}

4、页面脚本

src/views/core/lend/list.vue

<script>
import lendApi from '@/api/core/lend'

export default {
  data() {
    return {
      list: null // 列表
    }
  },

  created() {
    this.fetchData()
  },

  methods: {
    // 加载列表数据
    fetchData() {
      lendApi.getList().then(response => {
        this.list = response.data.list
      })
    }
  }
}
</script>

5、页面模板

src/views/core/lend/list.vue

<template>
  <div class="app-container">
    <!-- 列表 -->
    <el-table :data="list" stripe>
      <el-table-column type="index" label="序号" width="60" align="center" />
      <el-table-column prop="lendNo" label="标的编号" width="160" />
      <el-table-column prop="amount" label="标的金额" />
      <el-table-column prop="period" label="投资期数" />
      <el-table-column label="年化利率">
        <template slot-scope="scope">
          {{ scope.row.lendYearRate * 100 }}%
        </template>
      </el-table-column>
      <el-table-column prop="investAmount" label="已投金额" />
      <el-table-column prop="investNum" label="投资人数" />
      <el-table-column prop="publishDate" label="发布时间" width="150" />
      <el-table-column prop="lendStartDate" label="开始日期" />
      <el-table-column prop="lendEndDate" label="结束日期" />
      <el-table-column prop="param.returnMethod" label="还款方式" />
      <el-table-column prop="param.status" label="状态" />

      <el-table-column label="操作" width="150" align="center">
        <template slot-scope="scope">
          <el-button type="primary" size="mini">
            <router-link :to="'/core/lend/detail/' + scope.row.id">
              查看
            </router-link>
          </el-button>

          <el-button
            v-if="scope.row.status == 1"
            type="warning"
            size="mini"
            @click="makeLoan(scope.row.id)"
          >
            放款
          </el-button>
        </template>
      </el-table-column>
    </el-table>
  </div>
</template>
