一、借款信息列表展示

（一）需求

（二）后端

扩展实体对象

列表的结果需要关联查询，数据字典的数据也需要展示对应的文本内容而不是值，除了定义VO的方式，我们也可以使用扩展原有实体类的方式 

在BorrowInfo类中扩展以下字段

//扩展字段
@ApiModelProperty(value = "姓名")
@TableField(exist = false)
private String name;

@ApiModelProperty(value = "手机")
@TableField(exist = false)
private String mobile;

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

controller 

添加 AdminBorrowInfoController

@Api(tags = "借款管理")
@RestController
@RequestMapping("/admin/core/borrowInfo")
@Slf4j
public class AdminBorrowInfoController {

    @Resource
    private BorrowInfoService borrowInfoService;

    @ApiOperation("借款信息列表")
    @GetMapping("/list")
    public R list() {
        List<BorrowInfo>  borrowInfoList = borrowInfoService.selectList();
        return R.ok().data("list", borrowInfoList);
    }
}

service

 接口：BorrowInfoService

List<BorrowInfo> selectList();

实现：BorrowInfoServiceImpl

@Resource
private DictService dictService;

@Override
public List<BorrowInfo> selectList() {
    List<BorrowInfo> borrowInfoList = baseMapper.selectBorrowInfoList();
    borrowInfoList.forEach(borrowInfo -> {
        String returnMethod = dictService.getNameByParentDictCodeAndValue("returnMethod", borrowInfo.getReturnMethod());
        String moneyUse = dictService.getNameByParentDictCodeAndValue("moneyUse", borrowInfo.getMoneyUse());
        String status = BorrowInfoStatusEnum.getMsgByStatus(borrowInfo.getStatus());
        borrowInfo.getParam().put("returnMethod", returnMethod);
        borrowInfo.getParam().put("moneyUse", moneyUse);
        borrowInfo.getParam().put("status", status);
    });

    return borrowInfoList;
}

mapper

接口：BorrowInfoMapper

List<BorrowInfo> selectBorrowInfoList();

xml：BorrowInfoMapper.xml

<select id="selectBorrowInfoList" resultType="com.atguigu.srb.core.pojo.entity.BorrowInfo">
    SELECT
    bi.*,
    b.name,
    b.mobile
    FROM
    borrow_info AS bi
    LEFT JOIN borrower AS b ON bi.user_id = b.user_id
    WHERE bi.is_deleted = 0
</select>

（三）前端

创建页面组件src/views/core/borrow-info/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="name" label="借款人姓名" width="90" />
      <el-table-column prop="mobile" label="手机" />
      <el-table-column prop="amount" label="借款金额" />
      <el-table-column label="借款期限" width="90">
        <template slot-scope="scope">{
   
   { scope.row.period }}个月</template>
      </el-table-column>
      <el-table-column prop="param.returnMethod" label="还款方式" width="150" />
      <el-table-column prop="param.moneyUse" label="资金用途" width="100" />
      <el-table-column label="年化利率" width="90">
        <template slot-scope="scope">
          {
   
   { scope.row.borrowYearRate * 100 }}%
        </template>
      </el-table-column>
      <el-table-column prop="param.status" label="状态" width="100" />

      <el-table-column prop="createTime" label="申请时间" width="150" />

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

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

<script>
import borrowInfoApi from '@/api/core/borrow-info'

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

  created() {
    this.fetchData()
  },

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

配置路由 

src/router/index.js

在“借款管理”下添加子路由

      {
        path: 'info-list',
        name: 'coreBorrowInfoList',
        component: () => import('@/views/core/borrow-info/list'),
        meta: { title: '借款列表' }
      },
      {
        path: 'info-detail/:id',
        name: 'coreBorrowInfoDetail',
        component: () => import('@/views/core/borrow-info/detail'),
        meta: { title: '借款详情' },
        hidden: true
      }

定义api

创建 src/api/core/borrow-info.js

import request from '@/utils/request'

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

二、借款详情

（一）需求

借款详情展示借款信息与借款人信息

（二）后端

controller

AdminBorrowInfoController

@ApiOperation("获取借款信息")
@GetMapping("/show/{id}")
public R show(
    @ApiParam(value = "借款id", required = true)
    @PathVariable Long id) {
    Map<String, Object> borrowInfoDetail = borrowInfoService.getBorrowInfoDetail(id);
    return R.ok().data("borrowInfoDetail", borrowInfoDetail);
}

service

接口：BorrowInfoService

Map<String, Object> getBorrowInfoDetail(Long id);

实现：BorrowInfoServiceImpl

@Resource
private BorrowerMapper borrowerMapper;

@Resource
private BorrowerService borrowerService;

@Override
public Map<String, Object> getBorrowInfoDetail(Long id) {

    //查询借款对象
    BorrowInfo borrowInfo = baseMapper.selectById(id);
    //组装数据
    String returnMethod = dictService.getNameByParentDictCodeAndValue("returnMethod", borrowInfo.getReturnMethod());
    String moneyUse = dictService.getNameByParentDictCodeAndValue("moneyUse", borrowInfo.getMoneyUse());
    String status = BorrowInfoStatusEnum.getMsgByStatus(borrowInfo.getStatus());
    borrowInfo.getParam().put("returnMethod", returnMethod);
    borrowInfo.getParam().put("moneyUse", moneyUse);
    borrowInfo.getParam().put("status", status);

    //根据user_id获取借款人对象
    QueryWrapper<Borrower> borrowerQueryWrapper = new QueryWrapper<Borrower>();
    borrowerQueryWrapper.eq("user_id", borrowInfo.getUserId());
    Borrower borrower = borrowerMapper.selectOne(borrowerQueryWrapper);
    //组装借款人对象
    BorrowerDetailVO borrowerDetailVO = borrowerService.getBorrowerDetailVOById(borrower.getId());

    //组装数据
    Map<String, Object> result = new HashMap<>();
    result.put("borrowInfo", borrowInfo);
    result.put("borrower", borrowerDetailVO);
    return result;
}

（三）前端

定义api

  show(id) {
    return request({
      url: `/admin/core/borrowInfo/show/${id}`,
      method: 'get'
    })
  }

页面模板及脚本

src/views/core/borrow-info/detail.vue

<template>
  <div class="app-container">
    <h4>借款信息</h4>
    <table
      class="table table-striped table-condenseda table-bordered"
      width="100%"

        </tr>
      </tbody>
    </table>

    <h4>借款人信息</h4>
    <table

      <tbody>

        </tr>
      </tbody>
    </table>

    <el-row style="text-align: center; margin-top: 40px">
      <el-button @click="back">返回</el-button>
    </el-row>
  </div>
</template>

<script>
import borrowInfoApi from '@/api/core/borrow-info'
import '@/styles/show.css'
export default {
  data() {
    return {
      borrowInfoDetail: {
        borrowInfo: {},
        borrower: {},
      },
    }
  },
  created() {
    this.fetchData()
  },
  methods: {
    fetchData() {
      borrowInfoApi.show(this.$route.params.id).then((response) => {
        this.borrowInfoDetail = response.data.borrowInfoDetail
      })
    },

    back() {
      this.$router.push({ path: '/core/borrower/info-list' })
    },
  },
}
</script>

三、借款审批

（一）需求

管理平台借款审批，审批通过后产生标的，审批前我们需要跟借款人进行电话沟通，确定借款年化和平台服务费率（平台收益），借款年化可能根据实际情况调高或调低；起息日通常我们把它确定为募集结束时间（或放款时间）

（二）后端

定义VO对象

@Data
@ApiModel(description = "借款信息审批")
public class BorrowInfoApprovalVO {

    @ApiModelProperty(value = "id")
    private Long id;

    @ApiModelProperty(value = "状态")
    private Integer status;

    @ApiModelProperty(value = "审批内容")
    private String content;

    @ApiModelProperty(value = "标题")
    private String title;

    @ApiModelProperty(value = "年化利率")
    private BigDecimal lendYearRate;

    @ApiModelProperty(value = "平台服务费率")
    private BigDecimal serviceRate;

    @ApiModelProperty(value = "开始日期")
    private String lendStartDate;

    @ApiModelProperty(value = "描述信息")
    private String lendInfo;
}

controller

AdminBorrowInfoController

@ApiOperation("审批借款信息")
@PostMapping("/approval")
public R approval(@RequestBody BorrowInfoApprovalVO borrowInfoApprovalVO) {

    borrowInfoService.approval(borrowInfoApprovalVO);
    return R.ok().message("审批完成");
}

service 

接口：BorrowInfoService

void approval(BorrowInfoApprovalVO borrowInfoApprovalVO);

实现：BorrowInfoServiceImpl 

（三）前端

定义api

 src/api/core/borrow-info.js

  approval(borrowInfoApproval) {
    return request({
      url: '/admin/core/borrowInfo/approval',
      method: 'post',
      data: borrowInfoApproval
    })
  }

页面模板及脚本

src/views/core/borrow-info/list.vue

<template>
