若依配置教程(六)Excel导入功能实现

若依官网导入实现流程


一、前端index.vue

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();
    }
