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_${new Date().getTime()}.xlsx`)
    },
// 文件上传中处理
handleFileUploadProgress(event, file, fileList) {
  this.upload.isUploading = true;
},
// 文件上传成功处理
handleFileSuccess(response, file, fileList) {
  this.upload.open = false;
  this.upload.isUploading = false;
  this.$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();
}

---

---

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"
	accept=".xlsx, .xls"
	:headers="upload.headers"
	:action="upload.url + '?updateSupport=' + upload.updateSupport"
	:disabled="upload.isUploading"
	:on-progress="handleFileUploadProgress"
	:on-success="handleFileSuccess"
	: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.success(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 successNum = 0;
        int failureNum = 0;
        StringBuilder successMsg = new StringBuilder();
        StringBuilder failureMsg = new StringBuilder();
        for (SysHonor user : userList)
        {
            try
            {
                BeanValidators.validateWithException(validator, user);
                user.setCreateBy(operName);
                this.insertSysHonor(user);
                successNum++;
                successMsg.append("<br/>" + successNum + "、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
        {
            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();
    }
