上传页面jsp：

<form:form id="form1" name="form1" method="post"
			action="${turnToSaveOutcomeViewURL}" enctype="multipart/form-data">
			<table style="text-align: center; width: 100%;">
				<tr>
					<td class="tdRight">
						上传文件：
					</td>
					<td class="tdLeft">
						<input type="file" id="attachment" name="attachment" />
					</td>
				</tr>
				<tr>
					<td class="tdCenter" colspan="2">
						<a id="submitBtn1" class="majorButton"><span>提交</span> </a>
					</td>
				</tr>
			</table>
</form:form>

ApplicationContext.xml配置文件中的代码配置：

	<!-- 处理文件上传  portlet multipart resolver 2012-08-02-->
	<bean id="portletMultipartResolver"
		class="org.springframework.web.portlet.multipart.CommonsPortletMultipartResolver">
		<property name="maxUploadSize" value="10000000" />
	</bean>

Controller中代码部分：

	@RequestMapping(params = "action=turnToSaveOutcomeView")
	public void turnToSaveOutcomeView(ActionRequest request,
			ActionResponse response) throws IOException {
		System.out.println(this.getClass() + " void turnToSaveOutcomeView()");
		// 上传文件程序段开始================================================================
		// 转型为MultipartHttpRequest
		DefaultMultipartActionRequest multipartRequest = (DefaultMultipartActionRequest) request;
		// 根据前台的name名称得到上传的文件
		MultipartFile file = multipartRequest.getFile("attachment");
		// 获得文件名：
		String realFileName = file.getOriginalFilename();
		System.out.println("获得文件名：" + realFileName);
		// 获取路径
		String ctxPath = request.getContextPath();
		ctxPath = request.getPortletSession().getPortletContext().getRealPath(
				"/")+"uploadFile\\";
		System.out.println("路径：" + ctxPath);
		// 创建文件
		File dirPath = new File(ctxPath);
		if (!dirPath.exists()) {
			dirPath.mkdir();
		}
		String newFileName = (new Date()).getTime() + realFileName.substring(realFileName.indexOf("."));
		
		File uploadFile = new File(ctxPath + newFileName);
		FileCopyUtils.copy(file.getBytes(), uploadFile);
		// 上传文件程序段结束================================================================

		response.setRenderParameter("info", "保存成功");
		response.setRenderParameter("action", "turnToSaveOutcomeView");
	}

	@RequestMapping(params = "action=turnToSaveOutcomeView")
	public ModelAndView turnToSaveOutcomeView(RenderRequest request,
			RenderResponse response, String info) {
		System.out.println(this.getClass()
				+ " ModelAndView turnToSaveOutcomeView()");
		ModelAndView mv = new ModelAndView();
		mv.addObject("info", info);
		mv.setView("commit");
		return mv;
	}

上传的路径就是自己项目的：uploadFile文件夹下面
