若依官网导入实现流程
一、前端index.vue中
1.在所需模块的index.vue中的< script >< /script >中增加如下代码:
import { getToken } from "@/utils/auth";
// 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用户数据
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 + "/salary/salary/importData"
},
/** 导入按钮操作 */
handleImport() {
this.upload.title = "用户导入";
this.upload.open = true;
},
/** 下载模板操作 */
importTemplate() {
this.download('honor/honor/importTemplate', {
}, `user_template_${new Date().getTime()}.xlsx`)
},
// 文件上传中处理
handleFileUploadProgress(event, file, fileList) {
this.upload.isUploading = true;
},
// 文件上传成功处理
handleFileSu***ess(response, file, fileList) {
this.upload.open = false;
this.upload.isUploading = false;
this.$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();
}
2.在< template >< /template >中添加导入按钮事件:
<el-col :span="1.5">
<el-button
type="info"
icon="el-icon-upload2"
size="mini"
@click="handleImport"
v-hasPermi="['system:honor:import']"
>导入</el-button>
</el-col>
3.添加导入前端代码:
<!-- 用户导入对话框 -->
<el-dialog :title="upload.title" :visible.sync="upload.open" width="400px">
<el-upload
ref="upload"
:limit="1"
a***ept=".xlsx, .xls"
:headers="upload.headers"
:action="upload.url + '?updateSupport=' + upload.updateSupport"
:disabled="upload.isUploading"
:on-progress="handleFileUploadProgress"
:on-su***ess="handleFileSu***ess"
:auto-upload="false"
drag
>
<i class="el-icon-upload"></i>
<div class="el-upload__text">
将文件拖到此处,或
<em>点击上传</em>
</div>
<div class="el-upload__tip" slot="tip">
<el-checkbox v-model="upload.updateSupport" />是否更新已经存在的用户数据
<el-link type="info" style="font-size:12px" @click="importTemplate">下载模板</el-link>
</div>
<div class="el-upload__tip" style="color:red" slot="tip">提示:仅允许导入“xls”或“xlsx”格式文件!</div>
</el-upload>
<div slot="footer" class="dialog-footer">
<el-button type="primary" @click="submitFileForm">确 定</el-button>
<el-button @click="upload.open = false">取 消</el-button>
</div>
</el-dialog>
二、在模块文件夹(ruoyi-honor->src->domain->SysHonor)中:
在实体变量上(domain->SysHonor)添加@Excel注解,默认为导出导入,也可以单独设置仅导入Type.IMPORT:
三、在模块文件夹(ruoyi-honor->controller->SysHonorController)中添加导入方法:
爆红的有些需要修改名称,有些需要导入类,其中userService爆红,需要加一段代码: @Autowired private ISysHonorService userService;
处理方法看下图:
@Log(title = "用户管理", businessType = BusinessType.IMPORT)
@PostMapping("/importData")
public AjaxResult importData(MultipartFile file, boolean updateSupport) throws Exception
{
ExcelUtil<SysHonor> util = new ExcelUtil<SysHonor>(SysHonor.class);
List<SysHonor> userList = util.importExcel(file.getInputStream());
LoginUser loginUser = getLoginUser();
String operName = loginUser.getUsername();
String message = userService.importUser(userList, updateSupport, operName);
return AjaxResult.su***ess(message);
}
@GetMapping("/importTemplate")
public AjaxResult importTemplate()
{
ExcelUtil<SysHonor> util = new ExcelUtil<SysHonor>(SysHonor.class);
return util.importTemplateExcel("用户数据");
}
文件夹标错了:
在加入代码后,还会出现importUser爆红,这时需要根据提示创建类即可。
四、在在模块文件夹(ruoyi-honor->service->SysHonorServiceImpl)中添加:
/**
* 导入用户数据
*
* @param userList 用户数据列表
* @param isUpdateSupport 是否更新支持,如果已存在,则进行更新数据
* @param operName 操作用户
* @return 结果
*/
@Override
public String importsalary(List<SysHonor> userList, Boolean isUpdateSupport, String operName)
{
if (StringUtils.isNull(userList) || userList.size() == 0)
{
throw new ServiceException("导入用户数据不能为空!");
}
int su***essNum = 0;
int failureNum = 0;
StringBuilder su***essMsg = new StringBuilder();
StringBuilder failureMsg = new StringBuilder();
for (SysHonor user : userList)
{
try
{
BeanValidators.validateWithException(validator, user);
user.setCreateBy(operName);
this.insertSysHonor(user);
su***essNum++;
su***essMsg.append("<br/>" + su***essNum + "、账号 " + user.getUserName() + " 导入成功");
}
catch (Exception e)
{
failureNum++;
String msg = "<br/>" + failureNum + "、账号 " + user.getUserName() + " 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 ServiceException(failureMsg.toString());
}
else
{
su***essMsg.insert(0, "恭喜您,数据已全部导入成功!共 " + su***essNum + " 条,数据如下:");
}
return su***essMsg.toString();
}
