使用Spring CommonsMultipartResolver 上传文件

SpringMVCJavaStrutsJSP

可以在controller(spring mvc) 或者 action (struts mvc)
中直接使用CommonsMultipartResolver

...Controller...{

//创建一个通用的多部分解析器.
CommonsMultipartResolvercommonsMultipartResolver=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
MultipartHttpServletRequestmultipartRequest=
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...
MultipartFilefile=multipartRequest.getFile("file");

//上传后记录的文件...
FileimageFile=newFile("fileName");
//上传...
file.transferTo(imageFile);

}
}

...Controller...{

//创建一个通用的多部分解析器.
CommonsMultipartResolvercommonsMultipartResolver=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
MultipartHttpServletRequestmultipartRequest=
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...
MultipartFilefile=multipartRequest.getFile("file");

//上传后记录的文件...
FileimageFile=newFile("fileName");
//上传...
file.transferTo(imageFile);

}
}

也可以在spring配置文件中配置

也可以在Spring的配置文件中添加
Xml代码
<beanid=”multipartResolver”class=”org.springframework.web.multipart.commons.CommonsMultipartResolver”>
<propertyname=”defaultEncoding”value=”UTF-8″/>
</bean>

也可以在Spring的配置文件中添加
Xml代码
<beanid=”multipartResolver”class=”org.springframework.web.multipart.commons.CommonsMultipartResolver”>
<propertyname=”defaultEncoding”value=”UTF-8″/>
</bean>

jsp code

<formid=”fileUploadForm”method=”post”action=”XXX.do?method=fileUpload”enctype=”multipart/form-data”>
<tr>
<td>File:</td>
<td><inputtype=”file”name=”file”></td>
</tr>
<tr>
<td><inputtype=”hidden”name=”fileOwner”value=”1002″/></td>
<td><inputtype=”submit”value=”submit”></td>
</tr>
</form>

package net.hqit.action;

{
String path = request.getRealPath("/upload");
request.setAttribute("name",image.getOriginalFilename());
request.setAttribute("img","<img src='http://mn960mn.blog.163.com/blog/upload/"+image.getOriginalFilename()+"'></img>");
FileCopyUtils.copy(image.getBytes(),new File(path+"/"+image.getOriginalFilename()));
return "ok";
}
}

</bean>

<bean id="multipartResolver"

别忘了加入commons里的fileupload跟io两个ＪＡＲ包，这样就可以了。
