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

Java代码







...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);

}
}

...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);

}
}

也可以在spring配置文件中配置

Java代码







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>

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>

jsp code

Java代码







<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>

package net.hqit.action;

import java.io.File;

import java.io.IOException;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;

import org.springframework.util.FileCopyUtils;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.multipart.MultipartFile;

@Controller

public class FileUploadController {

@RequestMapping(value="/upload.do",method=RequestMethod.POST)

public String upload(@RequestParam("imageFile") MultipartFile image,HttpServletRequest request) throws IOException

{

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";

}

}

spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<property name="suffix" value=".jsp"/>

</bean>

<bean id="multipartResolver"

class="org.springframework.web.multipart.commons.CommonsMultipartResolver"

</beans>

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