认清现实，放弃幻想，准备斗争

借款信息列表

需求

一、后端实现

1、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 param = new HashMap<>();

2、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  borrowInfoList = borrowInfoService.selectList();
        return R.ok().data("list", borrowInfoList);
    }
}

实现：BorrowInfoServiceImpl 

@Resource
private DictService dictService;

@Override
public List selectList() {
    List 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;
}

4、Mapper

接口：BorrowInfoMapper

List selectBorrowInfoList();

xml：BorrowInfoMapper.xml 

    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

二、前端

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、页面脚本

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

5、页面模板

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