借款信息列表

需求

一、后端实现

1、entity

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实体类的方式

在BorrowInfo.java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<>();

2、controller

添加 AdminBorrowInfoController.java

package com.indi.srb.core.controller.admin;

@Api(tags = "借款管理")
@RestController
@RequestMapping("/admin/core/borrowInfo")
public class AdminBorrowInfoController {
     
    @Resource
    private BorrowInfoService borrowInfoService;

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

3、service

BorrowInfoService.java

    List<BorrowInfo> selectList();

BorrowInfoServiceImpl.java

    @Resource
    private DictService dictService;
    
    @Override
    public List<BorrowInfo> selectList() {
     
        List<BorrowInfo> borrowInfoList = baseMapper.selectBorrowInfoList();
        borrowInfoList.forEach(borrowInfo -> {
     
            setExtensionBorrowInfo(borrowInfo);
        });
        return borrowInfoList;
    }
    
    /**
     * 设置BorrowInfo扩展的字段
     * @param borrowInfo
     */
    private void setExtensionBorrowInfo(BorrowInfo borrowInfo) {
     
        String returnMethod = dictService.getNameByDictCodeAndValue("returnMethod", borrowInfo.getReturnMethod());
        String moneyUse = dictService.getNameByDictCodeAndValue("moneyUse", borrowInfo.getMoneyUse());
        String status = BorrowInfoStatusEnum.getMsgByStatus(borrowInfo.getStatus());

        borrowInfo.getParam().put("returnMethod", returnMethod);
        borrowInfo.getParam().put("moneyUse", moneyUse);
        borrowInfo.getParam().put("status", status);
    }    

4、mapper

BorrowInfoMapper.java

    List<BorrowInfo> selectBorrowInfoList();

BorrowInfoMapper.xml

	<select id="selectBorrowInfoList" resultType="com.indi.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 b.is_deleted = 0
	select>

二、前端实现

1、创建页面组件

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

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

2、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
      }

3、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'
    })
  }
}

4、template

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

<template>
  <div class="app-container">
    
    <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>

5、script

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

<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>

借款详情

需求

借款信息列表点击查看，进入借款详情展示借款信息与借款人信息

一、后端实现

1、controller

AdminBorrowInfoController.java

    @ApiOperation("借款详情")
    @GetMapping("/getBorrowInfoDetail/{id}")
    public R getBorrowInfoDetail(
            @ApiParam(value = "借款信息的id", required = true)
            @PathVariable Long id) {
     
        Map<String, Object> map = borrowInfoService.getBorrowInfoDetail(id);
        return R.ok().setData("borrowInfoDetail", map);
    }

2、service

BorrowInfoService.java

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

BorrowInfoServiceImpl.java

    @Resource
    private BorrowerService borrowerService;

    @Override
    public Map<String, Object> getBorrowInfoDetail(Long id) {
     
        // 借款信息
        BorrowInfo borrowInfo = baseMapper.selectById(id);
        setExtensionBorrowInfo(borrowInfo);

        Long userId = borrowInfo.getUserId();
        QueryWrapper<Borrower> queryWrapper = new QueryWrapper<>();
        queryWrapper.select("id").eq("user_id", userId);
        Borrower borrower = borrowerService.getBaseMapper().selectOne(queryWrapper);

        // 借款人信息
        BorrowerDetailVO borrowerDetailVO = borrowerService.getBorrowerDetailVO(borrower.getId());

        Map<String, Object> map = new HashMap<>();
        map.put("borrowInfo", borrowInfo);
        map.put("borrower", borrowerDetailVO);
        return map;
    }

二、前端

1、定义api

src/api/core/borrow-info.js

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

2、添加自定义css

src/styles/show.css

.app-container{
     
  background: #fff;
  position: absolute;
  width:100%;
  height: 100%;
  overflow: auto;
}

  color: #333;
  padding: 8px;
  line-height: 1.42857143;
  vertical-align: top;
  border-top: 1px solid #ddd;
}
.table>thead>tr>th, .table>tbody>tr>th, .table>tfoot>tr>th{

  border: 1px solid #ddd;
}
.active_content{
     
  padding: 0 20px  ;
  border-radius: 4px;
  border: 1px solid #ebeef5;
  background-color: #fff;
  overflow: hidden;
  color: #303133;
  transition: .3s;
  box-shadow: 0 2px 12px 0 rgba(0,0,0,.1);

}
.active_content h4{
     
  /*line-height: 0;*/
}
.active_content span{
     
  font-size: 12px;
  color: #999;
}

4、template

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

<template>
  <div class="app-container">

借款审批

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放款时间（或募集结束时间）

一、后端实现

1、vo

BorrowInfoApprovalVO .java

package com.indi.srb.core.pojo.vo;

@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;
}

2、controller

AdminBorrowInfoController.java

    @ApiOperation("审批借款信息")
    @PostMapping("/approval")
    public R approval(@RequestBody BorrowInfoApprovalVO borrowInfoApprovalVO){
     
        borrowInfoService.approval(borrowInfoApprovalVO);
        return R.ok().setMessage("审批完成");
    }

3、BorrowInfoService

BorrowInfoService.java

    void approval(BorrowInfoApprovalVO borrowInfoApprovalVO);

BorrowInfoServiceImpl.java

    @Resource
    private LendService lendService;	
	
	@Transactional(rollbackFor = Exception.class)
    @Override
    public void approval(BorrowInfoApprovalVO borrowInfoApprovalVO) {
     
        // 修改借款信息状态
        Long id = borrowInfoApprovalVO.getId();
        BorrowInfo borrowInfo = baseMapper.selectById(id);
        borrowInfo.setStatus(borrowInfoApprovalVO.getStatus());
        baseMapper.updateById(borrowInfo);

        // 如果借款状态为审核通过的话，则生成一个标的
        if (borrowInfoApprovalVO.getStatus().intValue() == BorrowInfoStatusEnum.CHECK_OK.getStatus().intValue()) {
     
            //TODO
            lendService.createLend(borrowInfoApprovalVO, borrowInfo);
        }
    }

3、编号辅助类

创建util包

LendNoUtils.java

package com.indi.srb.core.util;

public class LendNoUtils {
     

    public static String getNo() {
     

        LocalDateTime time=LocalDateTime.now();
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyyMMddHHmmss");
        String strDate = dtf.format(time);

        String result = "";
        Random random = new Random();
        for (int i = 0; i < 3; i++) {
     
            result += random.nextInt(10);
        }

        return strDate + result;
    }

    public static String getLendNo() {
     

        return "LEND" + getNo();
    }

    public static String getLendItemNo() {
     

        return "INVEST" + getNo();
    }

    public static String getLoanNo() {
     

        return "LOAN" + getNo();
    }

    public static String getReturnNo() {
     
        return "RETURN" + getNo();
    }


    public static Object getWithdrawNo() {
     
        return "WITHDRAW" + getNo();
    }


    public static String getReturnItemNo() {
     
        return "RETURNITEM" + getNo();
    }


    public static String getChargeNo() {
     

        return "CHARGE" + getNo();
    }

    /**
     * 获取交易编码
     */
    public static String getTransNo() {
     
        return "TRANS" + getNo();
    }

}

4、LendService

LendService.java

    void createLend(BorrowInfoApprovalVO borrowInfoApprovalVO, BorrowInfo borrowInfo);

LendServiceImpl.java

建议在idea中添加一个插件，GenerateAllSetter，可以快速生成对象的全部set方法。

    @Override
    public void createLend(BorrowInfoApprovalVO borrowInfoApprovalVO, BorrowInfo borrowInfo) {
     
        Lend lend = new Lend();
        lend.setUserId(borrowInfo.getUserId());
        lend.setBorrowInfoId(borrowInfo.getId());
        lend.setLendNo(LendNoUtils.getLendNo());
        lend.setTitle(borrowInfoApprovalVO.getTitle());
        lend.setAmount(borrowInfo.getAmount());
        lend.setPeriod(borrowInfo.getPeriod());

        // 年化率（转小数）
        BigDecimal lendYearRate = borrowInfoApprovalVO.getLendYearRate().divide(new BigDecimal(100));
        lend.setLendYearRate(lendYearRate);
        // 平台服务费率（转小数）
        lend.setServiceRate(borrowInfoApprovalVO.getServiceRate().divide(new BigDecimal(100)));

        lend.setReturnMethod(borrowInfo.getReturnMethod());
        lend.setLowestAmount(new BigDecimal(100));
        lend.setInvestAmount(new BigDecimal(0));
        lend.setInvestNum(0);
        lend.setPublishDate(LocalDateTime.now());

        // 起息日期
        DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
        LocalDate lendStartDate = LocalDate.parse(borrowInfoApprovalVO.getLendStartDate(), dateTimeFormatter);
        lend.setLendStartDate(lendStartDate);
        // 结束日期
        lend.setLendEndDate(lendStartDate.plusMonths(borrowInfo.getPeriod()));

        lend.setLendInfo(borrowInfoApprovalVO.getLendInfo());

        // 每月年化利率 = 年化 / 12，保留小数点后8位，去除最后一位
        BigDecimal monthRate = lendYearRate.divide(new BigDecimal(12), 8, BigDecimal.ROUND_DOWN);
        // 平台预期收益：借款金额 * 月年化 * 借款期限 
        BigDecimal exceptAmount = borrowInfo.getAmount().multiply(monthRate).multiply(new BigDecimal(borrowInfo.getPeriod()));
        lend.setExpectAmount(exceptAmount);

        lend.setRealAmount(new BigDecimal(0));
        lend.setStatus(LendStatusEnum.INVEST_RUN.getStatus());
        lend.setCheckTime(LocalDateTime.now());
        lend.setCheckAdminId(1L);

        baseMapper.insert(lend);
    }

二、前端实现

1、定义api

src/api/core/borrow-info.js

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

2、template

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

    
    <el-dialog title="审批" :visible.sync="dialogVisible" width="490px">
      <el-form label-position="right" label-width="100px">
        <el-form-item label="是否通过">
