管理端显示投资记录
一、后端接口
1、Controller
创建 AdminLendItemController
@Api(tags = "标的的投资")
@RestController
@RequestMapping("/admin/core/lendItem")
@Slf4j
public class AdminLendItemController {@Resourceprivate 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);}
}
2、Service

二、前端
1、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'})}
}

},
methods
fetchLendItemList() {lendItemApi.getList(this.$route.params.id).then(response => {this.lendItemList = response.data.list})
}
3、页面模板
views/core/lend/detail.vue
将投资记录放在借款人信息后面
