核心业务2：借款人申请借款额度

1.业务流程图

①用户在注册登陆账户绑定之后，点击立即借款进入到借款认证页

• A进入到借款认证页后，进入尚融宝判断借款状态来显示步骤
• B表单中的下拉列表数据在尚融宝查询数据字典获取
• C在上传照片时利用尚融宝上传数据到aliyun，在删除图片后删除aliyun中数据
• D点击提交后提交表单到尚融宝更新借款人数据
  

②如果A中已提交未审核则进入审核页

③如果A中已审核则将结果返回

2.借款人申请借款额度数据库设计

①用户数据表user_info

②借款人表borrower

③借款人绑定表borrower_attach

④三张表关系

• user_info通过user_id和borrower的user_id关联
• borrower的id和borrower_attach的borrow_id关联
• user_info即如果用户为借款人申请借款额度，用户信息表中包含了该用户为借款人的认证状态。
• borrower即包含了用户为借款人的基本信息
• borrower_attach表包含了用户为借款人的四张图片信息（房产证，轿车证，身份证正反面）

3.借款人申请额度流程

①前端

• 用户注册登陆绑定数据后
• 第一次借款认证填写信息提交表单
• 提交后再次访问提交表单页则直接进入认证中或者认证结果

②尚融宝后端

• 用户访问认证页
• 判断用户是否认证过，认证的状态。
• 如果没有认证过则前端显示表单页，后端需要在表单页显示时返回数据字典来初始化表单的下拉列表。
• 在填写表单时对图片的上传和删除同步到aliyun的oss
• 在填写完表单之后前端提交表单，后端根据表单数据更新user_info的借款人认证状态，根据token获得user_id以及表单信息来更新borrower和borrower_attach

4.代码逻辑

①前端对应表单对象

②前端请求接口

• 判断借款人认证状态
  
• 请求获取数据字典

• 请求上传和删除图片
  

• 提交表单
  

③前端复杂逻辑

• 需要完善表单信息。
  文件的表单信息需要上传成功后加入到表单中，如果删除文件，对应的也需要删除表单中的文件（删除文件如果删除表单，组件封装了调用成功后的响应结果）
• 刚进入认证页会先进入表单页再判断是否认证过，前端就算认证过也会闪过表单。
  修改步骤为null，必须查看认证结果后赋值，不会闪表单

5.后端代码逻辑

①前端调用的接口

• 开发接口
  
• 调用的接口
  

②后端复杂逻辑

• 获取下拉列表时根据dict_code去查对应的子节点
  需要先查询到dict_code的id然后根据此id去查父id为此id的数据返回（调用之前写的根据父id查询的service）
• 保存存款人信息时需要获取user_id绑定
  即需要用户先登录，此时可以从token中解析出user_id
• 根据表单信息更新借款人表单时
  需要先根据user_id查询出user_info的基本信息，补充表单信息更新borrower表
• 根据表单信息更新借款人附件表单时
  需要先查询借款人的id然后在附件表单中绑定借款人id
• 提交表单后也需要更新user_info的借款人认证状态
• 获取借款人认证状态
  可以从已登录的token中获取。然后根据id从borrower表中查询status，查询出数据则说明不是未认证返回status(1认证中2认证成功-1认证失败)，查询不出数据则是未认证返回status(0未认证)

③后端创建的接受前端对象

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

import com.atguigu.srb.core.pojo.entity.BorrowerAttach;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.util.List;

@Data
@ApiModel(description="借款人认证信息")
public class BorrowerVO{

    @ApiModelProperty(value = "性别（1：男 0：女）")
    private Integer sex;

    @ApiModelProperty(value = "年龄")
    private Integer age;

    @ApiModelProperty(value = "学历")
    private Integer education;

    @ApiModelProperty(value = "是否结婚（1：是 0：否）")
    private Boolean marry;

    @ApiModelProperty(value = "行业")
    private Integer industry;

    @ApiModelProperty(value = "月收入")
    private Integer income;

    @ApiModelProperty(value = "还款来源")
    private Integer returnSource;

    @ApiModelProperty(value = "联系人名称")
    private String contactsName;

    @ApiModelProperty(value = "联系人手机")
    private String contactsMobile;

    @ApiModelProperty(value = "联系人关系")
    private Integer contactsRelation;

    @ApiModelProperty(value = "借款人附件资料")
    private List<BorrowerAttach> borrowerAttachList;
}

④获取数据字典业务

• controller

package com.atguigu.srb.core.controller.api;


import com.atguigu.common.result.R;
import com.atguigu.srb.core.pojo.entity.Dict;
import com.atguigu.srb.core.service.DictService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.util.List;

@Api(tags = "数据字典")
@RestController
@RequestMapping("/api/core/dict")
@Slf4j
public class DictController {

    @Resource
    private DictService dictService;

    @ApiOperation("根据DictCode获取下级节点")
    @GetMapping("/findByDictCode/{dictCode}")
    public R findByDictCode(
            @ApiParam("节点编码")
            @PathVariable("dictCode") String dictCode){

        List<Dict> list =  dictService.findByDictCode(dictCode);
        return R.ok().data("dictList",list);

6.用户个人信息后管理员审批流程

①在后台管理系统添加借款人列表

②后台管理系统的借款人列表展示

③单击审批进入审批页的页面展示

④前后端联调

• 前端需要增加路由设置
• 需要增加借款人表单列表
• 需要增加额度审批表单

⑤前后端联调

• 后端需要获取借款人分页列表
• 获取借款人表单信息

7.前端代码逻辑

①前端对应表单对象

• 展示借款人列表表单
  
• 展示审批表单
  

②前端对应路由

• 前端增加借款管理路由（内部）
  
• 前端调用后端路由
  

③前端具体代码

• 增加内部导航路由
  srb-admin\src\router\index.js

{
    path: '/core/borrower',
    component: Layout,
    name: 'coreBorrower',
    meta: { title: '借款管理', icon: 'el-icon-s-unfold' },
    alwaysShow: true,
    children: [
      {
        path: 'list',
        name: 'coreBorrowerList',
        component: () => import('@/views/core/borrower/list'),
        meta: { title: '借款人列表' },
      },
      {
        path: 'detail/:id',
        name: 'coreBorrowerDetail',
        component: () => import('@/views/core/borrower/detail'),
        meta: { title: '借款人详情' },
        hidden: true,
      },
    ],
  },

• 增加调用后端api的接口
  srb-admin\src\api\core\borrower.js

import request from '@/utils/request'

export default {
  //根据分页信息和关键字查询借款人信息
  getPageList(page, limit, keyword) {
    return request({
      url: `/admin/core/borrower/list/${page}/${limit}`,
      method: 'get',
      params: { keyword },
    })
  },
  //根据id展示借款人认证信息
  show(id) {
    return request({
      url: `/admin/core/borrower/show/${id}`,
      method: 'get',
    })
  },
}

• 增加页面组件（借款人信息）
  srb-admin\src\views\core\borrower\list.vue

    <!--查询表单-->
    <el-form :inline="true">

④前端代码逻辑难点

• 展示图片信息（利用后端返回的url）
  

8.后端代码逻辑

①后端开发接口

②封装前端的对象

• 借款人表单返回borrower对象即可
• 审核表单vo

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

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.time.LocalDateTime;
import java.util.List;

@Data
@ApiModel(description="借款人信息详情")
public class BorrowerDetailVO {

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

    @ApiModelProperty(value = "姓名")
    private String name;

    @ApiModelProperty(value = "身份证号")
    private String idCard;

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

    @ApiModelProperty(value = "性别")
    private String sex;

    @ApiModelProperty(value = "年龄")
    private Integer age;

    @ApiModelProperty(value = "学历")
    private String education;

    @ApiModelProperty(value = "是否结婚")
    private String marry;

    @ApiModelProperty(value = "行业")
    private String industry;

    @ApiModelProperty(value = "月收入")
    private String income;

    @ApiModelProperty(value = "还款来源")
    private String returnSource;

    @ApiModelProperty(value = "联系人名称")
    private String contactsName;

    @ApiModelProperty(value = "联系人手机")
    private String contactsMobile;

    @ApiModelProperty(value = "联系人关系")
    private String contactsRelation;

    @ApiModelProperty(value = "审核状态")
    private String status;

    @ApiModelProperty(value = "创建时间")
    private LocalDateTime createTime;

    @ApiModelProperty(value = "借款人附件资料")
    private List<BorrowerAttachVO> borrowerAttachVOList;
}

• 审核表单的图片数据vo

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

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

@Data
@ApiModel(value="借款人附件资料")
public class BorrowerAttachVO {

    @ApiModelProperty(value = "图片类型（idCard1：身份证正面，idCard2：身份证反面，house：房产证，car：车）")
    private String imageType;

    @ApiModelProperty(value = "图片路径")
    private String imageUrl;
}

③开发接口

• controller

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

import com.atguigu.common.result.R;
import com.atguigu.srb.core.pojo.entity.Borrower;
import com.atguigu.srb.core.pojo.vo.BorrowerDetailVO;

import io.swagger.annotations.ApiParam;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.*;

import javax.annotation.Resource;

@Api(tags = "借款人管理")
@RestController
@RequestMapping("/admin/core/borrower")
@Slf4j
public class AdminBorrowerController {

    @Resource
    private BorrowerService borrowerService;

    @ApiOperation("获取借款人分页列表")
    @GetMapping("/list/{page}/{limit}")
    public R listPage(
            @ApiParam(value = "当前页码", required = true)
            @PathVariable Long page,

            @ApiParam(value = "每页记录数", required = true)
            @PathVariable Long limit,

            @ApiParam(value = "查询关键字", required = false)
            @RequestParam String keyword) {
        //这里的@RequestParam其实是可以省略的，但是在目前的swagger版本中（2.9.2）不能省略，
        //否则默认将没有注解的参数解析为body中的传递的数据

        Page<Borrower> pageParam = new Page<>(page, limit);
        IPage<Borrower> pageModel = borrowerService.listPage(pageParam, keyword);
        return R.ok().data("pageModel", pageModel);
    }

    @ApiOperation("获取借款人信息")
    @GetMapping("/show/{id}")
    public R show(
            @ApiParam(value = "借款人id", required = true)
            @PathVariable Long id) {
        //封装vo信息
        BorrowerDetailVO borrowerDetailVO = borrowerService.getBorrowerDetailVOById(id);
        return R.ok().data("borrowerDetailVO", borrowerDetailVO);
    }
}

• 展示借款人列表查询分页信息service
  com.atguigu.srb.core.service.BorrowerService

IPage<Borrower> listPage(Page<Borrower> pageParam, String keyword);

    /**
     * @param pageParam:
     * @param keyword:
     * @return IPage<Borrower>
     * @author Likejin
     * @description 根据页码和一页展示的数量去查询。或者包含查询条件关键字（姓名，手机号码，身份证）
     * @date 2023/4/16 9:52
     */

    @Override
    public IPage<Borrower> listPage(Page<Borrower> pageParam, String keyword) {
        if(StringUtils.isBlank(keyword)){
            return baseMapper.selectPage(pageParam,null);
        }
        QueryWrapper<Borrower> borrowerQueryWrapper = new QueryWrapper<>();
        borrowerQueryWrapper
                .or().like("id_card", keyword)
                .or().like("mobile", keyword)
                .orderByDesc("id")
                .orderByDesc("id");
        return baseMapper.selectPage(pageParam,borrowerQueryWrapper);
    }

• 封装审批表单service
  com.atguigu.srb.core.service.BorrowerService

BorrowerDetailVO getBorrowerDetailVOById(Long id);

/**
     * @param id:
     * @return BorrowerDetailVO
     * @author Likejin
     * @description 根据id封装前端所需对象BorrowerDetailVO
     * @date 2023/4/16 10:17
     */
    @Override
    public BorrowerDetailVO getBorrowerDetailVOById(Long id) {
        //获取借款人信息
        Borrower borrower = baseMapper.selectById(id);
        BorrowerDetailVO borrowerDetailVO = new BorrowerDetailVO();
        //对应字段的填充
        BeanUtils.copyProperties(borrower,borrowerDetailVO);

        //婚否
        borrowerDetailVO.setMarry(borrower.getMarry()?"是":"否");
        //性别
        borrowerDetailVO.setSex(borrower.getSex()==1?"男":"女");

        //计算下拉列表选中内容(borrower中存储数值了，需要通过数值获取相应的字符)
        //根据dict_code和value获取到相应的文本
        String education = dictService.getNameByParentDictCodeAndValue("education", borrower.getEducation());
        String industry = dictService.getNameByParentDictCodeAndValue("industry", borrower.getIndustry());
        String income = dictService.getNameByParentDictCodeAndValue("income", borrower.getIncome());
        String returnSource = dictService.getNameByParentDictCodeAndValue("returnSource", borrower.getReturnSource());
        String contactsRelation = dictService.getNameByParentDictCodeAndValue("relation", borrower.getContactsRelation());

        //设置下拉列表选中内容
        borrowerDetailVO.setEducation(education);
        borrowerDetailVO.setIndustry(industry);
        borrowerDetailVO.setIncome(income);
        borrowerDetailVO.setReturnSource(returnSource);
        borrowerDetailVO.setContactsRelation(contactsRelation);

        //审批状态,设置审批状态（通过status来获取文本值）
        String status = BorrowerStatusEnum.getMsgByStatus(borrower.getStatus());
        borrowerDetailVO.setStatus(status);

        //获取附件VO列表(个根据borrower_id查询所有的borrower的附件表并且封装为list)
        List<BorrowerAttachVO> borrowerAttachVOList =  borrowerAttachService.selectBorrowerAttachVOList(id);
        borrowerDetailVO.setBorrowerAttachVOList(borrowerAttachVOList);

        return borrowerDetailVO;

    }

• 封装审批表单BorrowerService调用DictService
  根据borrower信息的编码获取对应的字符串（根据value获得name展示在前端对应的行）
  
  com.atguigu.srb.core.service.DictService

String getNameByParentDictCodeAndValue(String dictCode, Integer value);

 /**
     * @param dictCode:
     * @param value:
     * @return String
     * @author Likejin
     * @description 根据父dict_code和value来获取具体文本值
     * @date 2023/4/16 10:23
     */
    @Override
    public String getNameByParentDictCodeAndValue(String dictCode, Integer value) {
        //根据父dict_code获取父id
        QueryWrapper<Dict> dictQueryWrapper = new QueryWrapper<>();
        dictQueryWrapper.eq("dict_code",dictCode);
        Dict parentDict = baseMapper.selectOne(dictQueryWrapper);
        if(parentDict == null){
            return "";
        }
        Long id = parentDict.getId();
        //根据获取的父id和value定位唯一一条子数据获得其name
        dictQueryWrapper = new QueryWrapper<>();
        dictQueryWrapper.eq("parent_id",id)
                .eq("value",value);
        Dict dict = baseMapper.selectOne(dictQueryWrapper);
        if(dict == null){
            return "";
        }
        String name = dict.getName();
        return name;
    }

• 封装审批表单BorrowerService调用BorrowerAttachService
  需要查出其下borrower对象下面的所有BorrowerAttach
  com.atguigu.srb.core.service.BorrowerAttachService

 List<BorrowerAttachVO> selectBorrowerAttachVOList(Long id);

 /**
     * @param id:
     * @return List<BorrowerAttachVO>
     * @author Likejin
     * @description 根据borrower的id获取所有的附件信息封装为列表
     * @date 2023/4/16 10:36
     */

    @Override
    public List<BorrowerAttachVO> selectBorrowerAttachVOList(Long id) {

        QueryWrapper<BorrowerAttach> borrowerAttachQueryWrapper = new QueryWrapper<>();
        borrowerAttachQueryWrapper.eq("borrower_id",id);
        List<BorrowerAttach> borrowerAttaches = baseMapper.selectList(borrowerAttachQueryWrapper);

        ArrayList<BorrowerAttachVO> borrowerAttachVOList = new ArrayList<>();
        //创建一个BorrowerAttachVO的列表
        borrowerAttaches.forEach(borrowerAttach -> {
            BorrowerAttachVO borrowerAttachVO = new BorrowerAttachVO();
            borrowerAttachVO.setImageType(borrowerAttach.getImageType());
            borrowerAttachVO.setImageUrl(borrowerAttach.getImageUrl());

            borrowerAttachVOList.add(borrowerAttachVO);
        });
        return borrowerAttachVOList;
    }

④后端代码逻辑难点

• 获取借款人列表
  关键字可传可不传，不传就是null，传了就是模糊查询
• 获取审批表单数据
  根据前端传入的borrower_id来获取表单数据信息。
  根据borrower_id查询borrower数据表获取基本信息。封装BorrowerDetailVO
  根据borrower的信息编码查dict数据表获取编码对应字符串。封装BorrowerDetailVO
  根据borrwer的id查询所有的borrower的附件。封装BorrowerDetailVO的borrowerAttachVOList<BorrowerAttachVO>

9.展示用户个人信息后管理员修改状态更改积分流程

①上述流程已经展示了用户个人信息

②管理员评估积分并审核

③审核通过

• 管理系统
  会员获得积分
  
  借款人状态认证通过
  
  前端借款人认证状态为等待认证结果
  

10.数据库涉及表

①用户积分表（展示用户积分修改明细）

user_intergral

③用户积分表和用户表和借款人表关联

• 用户积分表user_intergral的明细加起来则为用户表user_info的总积分
• 用户表通过user_id和借款人borrower表想关联
• 插入用户积分明细同时用户表和借款人表都会更新状态status为认证成功

11.前端代码逻辑

①数据对象

②调用接口

③代码

• 调用接口
  srb-admin\src\api\core\borrower.js

//封装审核表单对象提交
  approval(borrowerApproval) {
    return request({
      url: '/admin/core/borrower/approval',
      method: 'post',
      data: borrowerApproval,
    })
  },

• 更改表单
  srb-admin\src\views\core\borrower\detail.vue

 <!--审批模板-->
    <el-form label-width="170px" v-if="borrower.status === '认证中'">
      <el-form-item label="是否通过">
        <el-radio-group v-model="approvalForm.status">
          <el-radio :label="2">通过</el-radio>
          <el-radio :label="-1">不通过</el-radio>
        </el-radio-group>
      </el-form-item>

      <el-form-item v-if="approvalForm.status == 2" label="基本信息积分">
        <el-input v-model="approvalForm.infoIntegral" style="width: 140px" />
        <span style="color: indianred">（可获取30至100积分）</span>
      </el-form-item>

      <el-form-item v-if="approvalForm.status == 2" label="身份证信息是否正确">
        <el-radio-group v-model="approvalForm.isIdCardOk">
          <el-radio :label="true">是</el-radio>
          <el-radio :label="false">否</el-radio>
        </el-radio-group>
        <span style="color: indianred">（可获得积分30积分）</span>
      </el-form-item>

      <el-form-item v-if="approvalForm.status == 2" label="车辆信息是否正确">
        <el-radio-group v-model="approvalForm.isCarOk">
          <el-radio :label="true">是</el-radio>
          <el-radio :label="false">否</el-radio>
        </el-radio-group>
        <span style="color: indianred">（可获得积分60积分）</span>
      </el-form-item>

      <el-form-item v-if="approvalForm.status == 2" label="房产信息是否正确">
        <el-radio-group v-model="approvalForm.isHouseOk">
          <el-radio :label="true">是</el-radio>
          <el-radio :label="false">否</el-radio>
        </el-radio-group>
        <span style="color: indianred">（可获得积分100积分）</span>
      </el-form-item>

      <el-row style="text-align: center">
        <el-button type="primary" @click="approvalSubmit()">确定</el-button>
      </el-row>
    </el-form>

methods方法中添加

    //表单审批积分提交和状态修改
    approvalSubmit() {
      this.saveBtnDisabled = true
      //封装一个borrower_id（表单中没有）
      this.approvalForm.borrowerId = this.$route.params.id
      borrowerApi.approval(this.approvalForm).then((response) => {
        this.$message.success(response.message)
        this.$router.push({ path: '/core/borrower/list' })
      })
    },

④前端代码难点

• 需要更新user_info和borrower和user_integral表故需要borrow的id
  可以从this.$route.params.id获取id，因为是从外面表单点进来故保存了id

12.后端代码逻辑

①对应前端数据对象

• 注意id表单没有前端需要获得
  

②接口地址

文章来源地址https://www.toymoban.com/news/detail-414802.html

③代码实现

• controller
  com.atguigu.srb.core.controller.admin.AdminBorrowerController

 @ApiOperation("借款额度审批")
    @PostMapping("/approval")
    public R approval(@RequestBody BorrowerApprovalVO borrowerApprovalVO) {
        //额度审批的目标：
        // 在user_integral表添加积分明细。在user_info添加总积分。
        // 修改borrower表的借款申请审核状态。修改user_info的借款申请审核状态


        //得到审批结果表单（获取对应积分）
        borrowerService.approval(borrowerApprovalVO);
        return R.ok().message("审批完成");
    }

• service
  com.atguigu.srb.core.service.BorrowerService

void approval(BorrowerApprovalVO borrowerApprovalVO);

    /**
     * @param borrowerApprovalVO:

     */

    @Transactional(rollbackFor = Exception.class)
    @Override
    public void approval(BorrowerApprovalVO borrowerApprovalVO) {
        //注意：user_integral表存储积分明细，每一次积分变动的信息（基本信息 获得积分，身份证 获得的积分）

        //根据提交对象拿到借款人的id
        Long borrowerId = borrowerApprovalVO.getBorrowerId();

        //获取借款人对象
        Borrower borrower = baseMapper.selectById(borrowerId);

        //设置审核状态
        //前端传来的通过与不通过的status值（2，-1）
        borrower.setStatus(borrowerApprovalVO.getStatus());
        baseMapper.updateById(borrower);

        //获取用户id
        Long userId = borrower.getUserId();

        //获取用户对象（以便更改user_info的总积分integral）
        UserInfo userInfo = userInfoMapper.selectById(userId);
        //获取原始积分
        Integer integral = userInfo.getIntegral();

        //计算基本信息积分(更新user_integral的表)
        UserIntegral userIntegral = new UserIntegral();
        userIntegral.setUserId(userId);
        userIntegral.setIntegral(borrowerApprovalVO.getInfoIntegral());
        userIntegral.setContent("借款人基本信息");

        userIntegralMapper.insert(userIntegral);

        //要更新的积分
        int currentIntegral = integral + borrowerApprovalVO.getInfoIntegral();

        //身份证积分
        if(borrowerApprovalVO.getIsCarOk()){
            //计算基本信息积分(更新user_integral的表)
            userIntegral = new UserIntegral();
            userIntegral.setUserId(userId);
            userIntegral.setIntegral(IntegralEnum.BORROWER_IDCARD.getIntegral());
            userIntegral.setContent(IntegralEnum.BORROWER_IDCARD.getMsg());
            userIntegralMapper.insert(userIntegral);

            //加上身份证积分
            currentIntegral += IntegralEnum.BORROWER_IDCARD.getIntegral();
        }

        //房产积分
        if(borrowerApprovalVO.getIsHouseOk()) {
            userIntegral = new UserIntegral();
            userIntegral.setUserId(userId);
            userIntegral.setIntegral(IntegralEnum.BORROWER_HOUSE.getIntegral());
            userIntegral.setContent(IntegralEnum.BORROWER_HOUSE.getMsg());
            userIntegralMapper.insert(userIntegral);


            //加上房产积分
            currentIntegral += IntegralEnum.BORROWER_HOUSE.getIntegral();
        }

        //车辆信息
        if(borrowerApprovalVO.getIsCarOk()) {
            userIntegral = new UserIntegral();
            userIntegral.setUserId(userId);
            userIntegral.setIntegral(IntegralEnum.BORROWER_CAR.getIntegral());
            userIntegral.setContent(IntegralEnum.BORROWER_CAR.getMsg());
            userIntegralMapper.insert(userIntegral);


            //加上车辆积分
            currentIntegral += IntegralEnum.BORROWER_CAR.getIntegral();
        }

        //将总用户积分加起来存到user_info表中
        //修改用户总结分
        userInfo.setIntegral(currentIntegral);

        //修改用户审核状态
        userInfo.setBorrowAuthStatus(borrowerApprovalVO.getStatus());

        //更新user_info
        userInfoMapper.updateById(userInfo);
    }

④后端逻辑难点

• 后端目标
  在user_integral表添加积分明细。在user_info添加总积分。
  修改borrower表的借款申请审核状态。修改user_info的借款申请审核状态
• 只有borrower_id如何获得user_info和user_integral
  先从borrower表中查出对应的user_id，并更新borrower表状态，再利用user_id更改user_info的状态并且增加积分明细到user_integral，最后根据积分明细更改总积分到user_info
