## 一、需求介绍 ##

### （一）借款人申请借款 ###

需求描述，操作表：lend（标的表）

### （二）流程 ###

1.  标的产生：管理员通过借款审核后，产生先标的（投资人可以投标）
2.  查看标的列表

## 二、生成新标的 ##

创建枚举LendStatusEnum

@AllArgsConstructor
    @Getter
    public enum LendStatusEnum {
    
        CHECK(0, "待发布"),
        INVEST_RUN(1, "募资中"),
        PAY_RUN(2, "还款中"),
        PAY_OK(3, "已结清"),
        FINISH(4, "结标"),
        CANCEL(-1, "已撤标"),
        ;
    
        private Integer status;
        private String msg;
    
    
        public static String getMsgByStatus(int status) {
            LendStatusEnum arrObj[] = LendStatusEnum.values();
            for (LendStatusEnum obj : arrObj) {
                if (status == obj.getStatus().intValue()) {
                    return obj.getMsg();
                }
            }
            return "";
        }
    }

service-core中添加辅助类（生成类似订单号一样的编号）：util.LendNoUtils

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();
        }
    
    }

**service**

BorrowInfoServiceImpl 实现：

@Override
        public void approval(BorrowInfoApprovalVO borrowInfoApprovalVO) {
    
            // 修改审批状态 borrow_info
            Long borrowId = borrowInfoApprovalVO.getId();
            BorrowInfo borrowInfo = borrowInfoMapper.selectById(borrowId);
            borrowInfo.setStatus(borrowInfoApprovalVO.getStatus());
            borrowInfoMapper.updateById(borrowInfo);
    
            // 如何审核成功添加新标的
            if(borrowInfoApprovalVO.getStatus().intValue() == BorrowInfoStatusEnum.CHECK_OK.getStatus().intValue()) {
                lendService.createLend(borrowInfoApprovalVO, borrowInfo);
            }
        }

LendService 接口

void createLend(BorrowInfoApprovalVO borrowInfoApprovalVO, BorrowInfo borrowInfo);

LendServiceImpl 实现：生成标的

@Override
    public void createLend(BorrowInfoApprovalVO borrowInfoApprovalVO, BorrowInfo borrowInfo) {
        Lend lend = new Lend();
        lend.setUserId(borrowInfo.getUserId());
        lend.setBorrowInfoId(borrowInfo.getId());
        lend.setLendNo(LendNoUtils.getLendNo());//生成编号
        lend.setTitle(borrowInfoApprovalVO.getTitle());
        lend.setAmount(borrowInfo.getAmount());
        lend.setPeriod(borrowInfo.getPeriod());
        lend.setLendYearRate(borrowInfoApprovalVO.getLendYearRate().divide(new BigDecimal(100)));//从审批对象中获取
        lend.setServiceRate(borrowInfoApprovalVO.getServiceRate().divide(new BigDecimal(100)));//从审批对象中获取
        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 dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd");
        LocalDate lendStartDate = LocalDate.parse(borrowInfoApprovalVO.getLendStartDate(), dtf);
        lend.setLendStartDate(lendStartDate);
        //结束日期
        LocalDate lendEndDate = lendStartDate.plusMonths(borrowInfo.getPeriod());
        lend.setLendEndDate(lendEndDate);
    
        lend.setLendInfo(borrowInfoApprovalVO.getLendInfo());//描述
    
        //平台预期收益
        //        月年化 = 年化 / 12
        BigDecimal monthRate = lend.getServiceRate().divide(new BigDecimal(12), 8, BigDecimal.ROUND_DOWN);
        //        平台收益 = 标的金额 * 月年化 * 期数
        BigDecimal expectAmount = lend.getAmount().multiply(monthRate).multiply(new BigDecimal(lend.getPeriod()));
        lend.setExpectAmount(expectAmount);
    
        //实际收益
        lend.setRealAmount(new BigDecimal(0));
        //状态
        lend.setStatus(LendStatusEnum.INVEST_RUN.getStatus());
        //审核时间
        lend.setCheckTime(LocalDateTime.now());
        //审核人
        lend.setCheckAdminId(1L);
    
        baseMapper.insert(lend);
    }

## 三、标的列表 ##

### （一）后端 ###

**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<>();

**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);
        }
    }

**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 ###

**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'
        })
      }
    }

**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
          }
        ]
      },

创建 src/views/core/lend/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="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="params.returnMethod" label="还款方式" />
          <el-table-column prop="params.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>
    
    <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
          })
        },
      }
    }

## 四、标的详情 ##

### （一）后端 ###

**controller**

AdminLendController

@ApiOperation("获取标的信息")
    @GetMapping("/show/{id}")
    public R show(
        @ApiParam(value = "标的id", required = true)
        @PathVariable Long id) {
        Map<String, Object> result = lendService.getLendDetail(id);
        return R.ok().data("lendDetail", result);
    }

**service**

接口：LendService

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

实现：LendServiceImpl

@Resource
    private BorrowerMapper borrowerMapper;
    
    @Resource
    private BorrowerService borrowerService;
    
    @Override
    public Map<String, Object> getLendDetail(Long id) {
    	
        //查询标的对象
        Lend lend = baseMapper.selectById(id);
        //组装数据
        String returnMethod = dictService.getNameByParentDictCodeAndValue("returnMethod", lend.getReturnMethod());
        String status = LendStatusEnum.getMsgByStatus(lend.getStatus());
        lend.getParam().put("returnMethod", returnMethod);
        lend.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", lend.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("lend", lend);
        result.put("borrower", borrowerDetailVO);
    
        return result;
    }

### （二）前端 ###

**定义api**

src/api/core/lend.js

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

**页面模板及脚本**

src/views/core/lend/detail.vue

<template>
      <div class="app-container">
        <h4>标的信息</h4>
        <table
          class="table table-striped table-condenseda table-bordered"
