若依代码生成自带导入功能

1 修改ruoyi-generator下resources下vm.java.controller

• 新增导出模板接口

/**
     * 导出模板
     */
    @PostMapping("/importTemplate")
    public void importTemplate(HttpServletResponse response)
    {
    
    
        ExcelUtil<${
    
    ClassName}> util = new ExcelUtil<${
    
    ClassName}>(${
    
    ClassName}.class);
        util.importTemplateExcel(response, "${functionName}数据");
    }

• 新增导入数据

    /**
     * 导入数据
     */
    @Log(title = "${functionName}", businessType = BusinessType.IMPORT)
    @PreAuthorize("@ss.hasPermi('${permissionPrefix}:import')")
    @PostMapping("/importData")
    public AjaxResult importData(MultipartFile file, boolean updateSupport) throws Exception
    {
    
    
        ExcelUtil<${
    
    ClassName}> util = new ExcelUtil<${
    
    ClassName}>(${
    
    ClassName}.class);
        List<${
    
    ClassName}> list = util.importExcel(file.getInputStream());
        int count = 0;
        for (${
    
    ClassName} ${
    
    className} : list) {
    
    
            int i = ${
    
    className}Service.insert${
    
    ClassName}(${
    
    className});
            count = count + i;
        }
        return AjaxResult.success("导入成功" + count + "条信息！");
    }

2 修改vue下index.vue.vm文件

• 新增方法

/** 下载模板操作 */
    importTemplate() {
    
    
      this.download('${moduleName}/${businessName}/importTemplate', {
    
    
      }, `template_#[[${
      
      new Date().getTime()}]]#.xlsx`)
    },
    /** 导入按钮操作 */
    handleImport() {
    
    
      this.upload.title = "${functionName}导入";
      this.upload.open = true;
    },
    // 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("<div style='overflow: auto;overflow-x: hidden;max-height: 70vh;padding: 10px 20px 0;'>" + response.msg + "</div>", "导入结果", {
    
     dangerouslyUseHTMLString: true });
      this.getList();
    },
    // 提交上传文件
    submitFileForm() {
    
    
      this.$refs.upload.submit();
    }

• 新增data

// 导入参数
      upload: {
    
    
        // 是否显示弹出层（导入）
        open: false,
        // 弹出层标题（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 + "/${moduleName}/${businessName}/importData"
      },

• 新增对话框

<!-- 导入对话框 -->
    <el-dialog :title="upload.title" :visible.sync="upload.open" width="400px" append-to-body>
      <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
