controller

创建 AdminLendItemController

@Api(tags = "标的的投资")
@RestController
@RequestMapping("/admin/core/lendItem")
@Slf4j
public class AdminLendItemController {

    @Resource
    private LendItemService lendItemService;

    @ApiOperation("获取列表")
    @GetMapping("/list/{lendId}")
    public R list(
            @ApiParam(value = "标的id", required = true)
            @PathVariable Long lendId) {
        List<LendItem> list = lendItemService.selectByLendId(lendId);
        return R.ok().data("list", list);
    }
}

service

接口：LendItemService

List<LendItem> selectByLendId(Long lendId);

实现：LendItemServiceImpl

@Override
public List<LendItem> selectByLendId(Long lendId) {
    QueryWrapper<LendItem> queryWrapper = new QueryWrapper();
    queryWrapper.eq("lend_id", lendId);
    List<LendItem> lendItemList = baseMapper.selectList(queryWrapper);
    return lendItemList;
}

（二）前端

创建api

api/core/lend-item.js

import request from '@/utils/request'

export default {
  getList(lendId) {
    return request({
      url: `/admin/core/lendItem/list/` + lendId,
      method: 'get'
    })
  }
}

页面脚本

views/core/lend/detail.vue

import lendItemApi from '@/api/core/lend-item'

data() {
  return {
    ......,

    lendItemList: [] //投资列表
  }
},

created() {
  if (this.$route.params.id) {
    ......

    // 投资记录
    this.fetchLendItemList()
  }
},

 methods

fetchLendItemList() {
  lendItemApi.getList(this.$route.params.id).then(response => {
    this.lendItemList = response.data.list
  })
}

页面模板

views/core/lend/detail.vue

将投资记录放在借款人信息后面

<h4>投资记录</h4>
<el-table :data="lendItemList" stripe style="width: 100%" border>
    <el-table-column type="index" label="序号" width="70" align="center" />

        this.lendReturnList = response.data.list
    })
}

页面模板

views/core/lend/detail.vue

将还款计划放在投资记录后面

<h4>还款计划</h4>
