HTML5+Spring-MVC实现上传图片本地保存

以下就是具体的代码：

1.在jsp页面中的代码：

<span style="font-size:24px;"><form method="post" action="<%=rootPath%>/complaint" onSubmit="return emptyCheck()" enctype="multipart/form-data">
					<div id="container4-2" class="font20" style="background-color:#9fa0a0;margin-top:px;padding-top:0px;
					text-align:center;border:0px;
					border-bottom-left-radius:3px;border-bottom-right-radius: 3px;
					color:#ffffff;">
						<div  style="margin-top:2px;"></div>
						<!-- <input type="file" value="上传图片" style="border-width: "/> -->
						<input type="file" name="file" style="position: absolute;opacity: 0.00"/>

					</div>
</form></span>

2.在Controller中的代码

 CommonsMultipartResolver multipartResolver =
                new CommonsMultipartResolver(request.getSession().getServletContext());
              //先判断request中是否包涵multipart类型的数据，
              if(multipartResolver.isMultipart(request)){
             //再将request中的数据转化成multipart类型的数据
                   MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
                   Iterator iter = multiRequest.getFileNames();
                   while(iter.hasNext()){
                        MultipartFile file = multiRequest.getFile((String)iter.next());
                        if(file != null){
                             fileName = file.getOriginalFilename();

                            String typeString=fileName.substring(fileName.lastIndexOf("."));
                             SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");

                            String id = sdf.format(new Date());

                            nameString=id+typeString;

                             path = "C:\\newtomcat\\webapps\\mobile\\userImg";
                             localFile = new File(path , nameString);

                             clientComplaint.setPath(localFile.getPath());//
                             //写文件到本地
                             try {
                                FileUtils.copyInputStreamToFile(file.getInputStream(),new File(path,nameString));
                            } catch (IOException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            }
                        }
                   }
 }

3.在spring-mvc的配置文件中配置信息：

<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="maxUploadSize" value="209715200" />
		<property name="defaultEncoding" value="UTF-8" />
		<property name="resolveLazily" value="true" />
		<!-- 延迟加载 -->
</bean>
