微服务项目：尚融宝（40）（核心业务流程：申请借款额度（3））

认清现实，放弃幻想，准备斗争

一、后端开发

1、定义VO对象

service-core微服务，创建BorrowerVO

@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 borrowerAttachList;
}

2、定义枚举

BorrowerStatusEnum

数据库设计中对应认证状态status （0：未认证，1：认证中， 2：认证通过， -1：认证失败）

3、controller

service-core中在BorrowerController中定义接口方法

@Api(tags = "借款人")
@RestController
@RequestMapping("/api/core/borrower")
@Slf4j
public class BorrowerController {
 
    @Resource
    private BorrowerService borrowerService;
 
    @ApiOperation("保存借款人信息")
    @PostMapping("/auth/save")
    public R save(@RequestBody BorrowerVO borrowerVO, HttpServletRequest request) {
        String token = request.getHeader("token");
        Long userId = JwtUtils.getUserId(token);
        borrowerService.saveBorrowerVOByUserId(borrowerVO, userId);
        return R.ok().message("信息提交成功");
    }
}

6、service

接口：BorrowerService 

void saveBorrowerVOByUserId(BorrowerVO borrowerVO, Long userId);

实现：BorrowerServiceImpl 

@Resource
private BorrowerAttachMapper borrowerAttachMapper;
 
@Resource
private UserInfoMapper userInfoMapper;
 
@Transactional(rollbackFor = Exception.class)
@Override
public void saveBorrowerVOByUserId(BorrowerVO borrowerVO, Long userId) {
 
    UserInfo userInfo = userInfoMapper.selectById(userId);
 
    //保存借款人信息
    Borrower borrower = new Borrower();
    BeanUtils.copyProperties(borrowerVO, borrower);
    borrower.setUserId(userId);
    borrower.setName(userInfo.getName());
    borrower.setIdCard(userInfo.getIdCard());
    borrower.setMobile(userInfo.getMobile());
    borrower.setStatus(BorrowerStatusEnum.AUTH_RUN.getStatus());//认证中
    baseMapper.insert(borrower);
 
    //保存附件
    List borrowerAttachList = borrowerVO.getBorrowerAttachList();
    borrowerAttachList.forEach(borrowerAttach -> {
        borrowerAttach.setBorrowerId(borrower.getId());
        borrowerAttachMapper.insert(borrowerAttach);
    });
    
    //更新会员状态，更新为认证中
    userInfo.setBorrowAuthStatus(BorrowerStatusEnum.AUTH_RUN.getStatus());
    userInfoMapper.updateById(userInfo);
}

二、前端整合

pages/user/borrower.vue 脚本

save() {
  // debugger
  this.submitBtnDisabled = true
  this.$axios
    .$post('/api/core/borrower/save', this.borrower)
    .then((response) => {
      this.active = 1
    })
},

 

一、获取借款人状态

1、BorrowerController

@ApiOperation("获取借款人认证状态")
@GetMapping("/auth/getBorrowerStatus")
public R getBorrowerStatus(HttpServletRequest request){
    String token = request.getHeader("token");
    Long userId = JwtUtils.getUserId(token);
    Integer status = borrowerService.getStatusByUserId(userId);
    return R.ok().data("borrowerStatus", status);
}

2、service

接口：BorrowerService

Integer getStatusByUserId(Long userId);

实现：BorrowerServiceImpl 

@Override
public Integer getStatusByUserId(Long userId) {
 
    QueryWrapper borrowerQueryWrapper = new QueryWrapper<>();
    borrowerQueryWrapper.select("status").eq("user_id", userId);
    List
