form表单提交action后，接收到的值为null.

我是直接采用属性封装：
Action中定义各个的属性要与对应form中的参数同名，并提供GET/SET方法；
这是jsp页面的代码

	<!-- 导入数据面板 -->
	<div id="dlg2" class="easyui-dialog" style="width:400px;height:180px;padding:10px 20px"
            closed="true" buttons="#dlg-buttons2">
        <form id="uploadForm" action="<%=contextPath%>/base/cmorganization!export.gx" method="post" enctype="multipart/form-data">
        	<table>
        		<tr>
        			<td>下载模版：</td>
        			<td><a href="javascript:void(0)" class="easyui-linkbutton"  onclick="downloadTemplate()">导入模版</a></td>
        		</tr>
        		<tr>
        			<td>上传文件：</td>
        			<td><input type="text" name=cmorganizationUploadFile></td><!--
                                <td><input type="text" name=cmorganizationUploadFile></td>-->
        		</tr>
        	</table>
        </form>
	</div>

	<div id="dlg-buttons2">
		<a href="javascript:void(0)" class="easyui-linkbutton" iconCls="icon-ok" onclick="uploadFile()">上传</a>
		<a href="javascript:void(0)" class="easyui-linkbutton" iconCls="icon-cancel" onclick="javascript:$('#dlg2').dialog('close')">关闭</a>
	</div>

这是提交方法

	// 上传
	var uploadFile = function(){
		$.post(gx.contextPath + '/base/cmorganization!upload.gx',gx.serializeObject($('uploadForm')),function(result) {
			if (result.success) {
				var result=eval('('+result+')');
				if(result.errorMsg){
					$.messager.alert("系统提示",result.errorMsg);
				}else{
					$.messager.alert("系统提示","上传成功");
					$("#dlg2").dialog("close");
					$("#dg").datagrid("reload");
				}
			}
			}, 'json');
		}

这是action中的代码

	private File cmorganizationUploadFile; // 导入文件

	public File getCmorganizationUploadFile() {
		return cmorganizationUploadFile;
	}


	public void setCmorganizationUploadFile(File cmorganizationUploadFile) {
		this.cmorganizationUploadFile = cmorganizationUploadFile;
	}
        	public String upload() throws Exception {
		System.out.println("进入action了！");
		System.out.println("=============="+cmorganizationUploadFile);
		/*POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream(cmorganizationUploadFile));
		HSSFWorkbook wb = new HSSFWorkbook(fs);
		HSSFSheet hssfSheet = wb.getSheetAt(0);
		if (hssfSheet != null) {
			for(int rowNum = 1; rowNum <= hssfSheet.getLastRowNum(); rowNum++) {
				HSSFRow hssfRow = hssfSheet.getRow(rowNum);
				if(hssfRow == null) {
					continue;
				}
				System.out.println(ExcelUtil.formatCell(hssfRow.getCell(0)));
				TCrCmOrganization cmOrganization = new TCrCmOrganization();
				cmOrganization.setCmName(ExcelUtil.formatCell(hssfRow.getCell(0)));
				cmOrganization.setCmTimeks(DateUtil.stringToDate(ExcelUtil.formatCell(hssfRow.getCell(1))));
				cmOrganization.setCmTimejs(DateUtil.stringToDate(ExcelUtil.formatCell(hssfRow.getCell(2))));
				cmOrganization.setCmOrganizer(ExcelUtil.formatCell(hssfRow.getCell(3)));
				cmOrganization.setCmCapacity(ExcelUtil.formatCell(hssfRow.getCell(4)));
				cmOrganization.setCmContent(ExcelUtil.formatCell(hssfRow.getCell(5)));
				cmOrganization.setCmHost(ExcelUtil.formatCell(hssfRow.getCell(6)));
				cmOrganization.setCmRecordpeople(ExcelUtil.formatCell(hssfRow.getCell(7)));
				cmOrganization.setCmSummaryLevel(ExcelUtil.formatCell(hssfRow.getCell(8)));
				service.save(cmOrganization);
			}
		}*/
		JSONObject result=new JSONObject();
		result.put("success", "true");
		ResponseUtil.write(ServletActionContext.getResponse(), result);
		return null;
	}

后台打印结果
进入action了！
==============null

本来是这样的

<td><input type="file" name=cmorganizationUploadFile></td>

但是传过去报空指针异常，所以我想是不是file不能用，就换成了text,但还是null.

[Zerlinda_Li]

	private String cmorganizationUploadFile; // 导入文件

	public String getCmorganizationUploadFile() {
		return cmorganizationUploadFile;
	}


	public void setCmorganizationUploadFile(String cmorganizationUploadFile) {
		this.cmorganizationUploadFile = cmorganizationUploadFile;
	}

这个

文件上传不用form的话，就得借助插件了，你这种写法是不行的，serializeObject应该没法序列化file。

[snailjumpjump]

你的form表单里加了这个enctype="multipart/form-data"，出了type=file类型的可以直接在Action里面接收，其他的好像要判断一下的，而且上传文件不是应该是<input type="file"/>吗？你这里怎么是个type="text'

<input type="file" enctype="multipart/form-data">
