一、后端
java">
@Log(title = "公交站牌", businessType = BusinessType.IMPORT)
@PreAuthorize("@ss.hasPermi('busStop:busStop:import')")
@PostMapping("/importData")
public AjaxResult importData(MultipartFile file, boolean updateSupport) throws Exception
{
ExcelUtil<BusStop> util = new ExcelUtil<BusStop>(BusStop.class);
List<BusStop> busStopList = util.importExcel(file.getInputStream());
LoginUser loginUser = tokenService.getLoginUser(ServletUtils.getRequest());
String operName = loginUser.getUsername();
String message = busStopService.importUser(busStopList, updateSupport, operName);
return AjaxResult.success(message);
}
@GetMapping("/importTemplate")
public AjaxResult importTemplate()
{
ExcelUtil<BusStop> util = new ExcelUtil<BusStop>(BusStop.class);
return util.importTemplateExcel("公交站牌数据");
}
实现类中的
java"> /**
* 导入公交站牌信息
* @param busStopList
* @param isUpdateSupport
* @param operName
* @return
*/
@Override
public String importUser(List<BusStop> busStopList, boolean isUpdateSupport, String operName) {
if (StringUtils.isNull(busStopList) || busStopList.size() == 0)
{
throw new CustomException("导入公交站牌数据不能为空!");
}
int successNum = 0;
int failureNum = 0;
StringBuilder successMsg = new StringBuilder();
StringBuilder failureMsg = new StringBuilder();
for (BusStop busStop : busStopList)
{
try
{
// 验证是否存在这个公交站牌
SysUser u = busStopMapper.selectBusStopByWfcId(busStop.getWfcId());
if (StringUtils.isNull(u))
{
busStop.setCreateBy(operName);
this.insertBusStop(busStop);
successNum++;
successMsg.append("<br/>" + successNum + "、站牌 " + busStop.getWfcId() + " 导入成功");
}
else if (isUpdateSupport)
{
busStop.setUpdateBy(operName);
this.updateBusStop(busStop);
successNum++;
successMsg.append("<br/>" + successNum + "、站牌 " + busStop.getWfcId() + " 更新成功");
}
else
{

}
}
catch (Exception e)
{

String msg = "<br/>" + failureNum + "、站牌 " + busStop.getWfcId() + " 导入失败:";
failureMsg.append(msg + e.getMessage());
//log.error(msg, e);
}
}
if (failureNum > 0)
{
failureMsg.insert(0, "很抱歉,导入失败!共 " + failureNum + " 条数据格式不正确,错误如下:");
throw new CustomException(failureMsg.toString());
}
else
{
successMsg.insert(0, "恭喜您,数据已全部导入成功!共 " + successNum + " 条,数据如下:");
}
return successMsg.toString();
}
二、前端
data return中
java">// 用户导入参数
upload: {
// 是否显示弹出层(用户导入)
open: false,
// 弹出层标题(用户导入)
title: "",
// 是否禁用上传
isUploading: false,
// 是否更新已经存在的站牌数据
updateSupport: 0,
// 设置上传的请求头部
headers: { Authorization: "Bearer " + getToken() },
// 上传的地址
url: process.env.VUE_APP_BASE_API + "/busStop/busStop/importData"
},
methods中放置
java"> /** 导入按钮操作 */
handleImport() {
this.upload.title = "站牌导入";
this.upload.open = true;
},
/** 下载模板操作 */
importTemplate() {
importTemplate().then(response => {
this.download(response.msg);
});
},
// 文件上传中处理
handleFileUploadProgress(event, file, fileList) {
this.upload.isUploading = true;
},
// 文件上传成功处理
handleFileSuccess(response, file, fileList) {
this.upload.open = false;
this.upload.isUploading = false;
this.$refs.upload.clearFiles();
this.$alert(response.msg, "导入结果", { dangerouslyUseHTMLString: true });
this.getList();
},
// 提交上传文件
submitFileForm() {
this.$refs.upload.submit();
}
temple中放置
