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-uploadref="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(); }
