Spring CommonsMultipartResolver 上传文件

...Controller...{

//创建一个通用的多部分解析器.

CommonsMultipartResolver commonsMultipartResolver = new

CommonsMultipartResolver(request.getSession().getServletContext());

//设置编码

commonsMultipartResolver.setDefaultEncoding(”utf-8″);

//判断 request 是否有文件上传,即多部分请求...

if (commonsMultipartResolver.isMultipart(request))

{

//转换成多部分request

MultipartHttpServletRequest multipartRequest =

commonsMultipartResolver.resolveMultipart(request);

// file 是指 文件上传标签的 name=值

// 根据 name 获取上传的文件...

MultipartFile file = multipartRequest.getFile("file");

//上传后记录的文件...

File imageFile = new File("fileName");

//上传...

file.transferTo(imageFile);

}

}

Form

也可以在Spring的配置文件中添加

Xml代码

<bean id=”multipartResolver” class=”org.springframework.web.multipart.commons.CommonsMultipartResolver”>

<property name=”defaultEncoding” value=”UTF-8″ />

</bean>

配置这个后就只需要编写以下代码即可

MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
MultipartFile mfile1 = multipartRequest.getFile("file");

<form id=”fileUploadForm” method=”post” action=”XXX.do?method=fileUpload” enctype=”multipart/form-data”>

<tr>

<td>File:</td>

<td><input type=”file” name=”file”></td>

</tr>

<tr>

<td><input type=”hidden” name=”fileOwner” value=”1002″/></td>

<td><input type=”submit” value=”submit”></td>

</tr>

</form>
