Flex+Java多文件上传

结合网上的资料修改一下，实现了两种不同界面的多文件上传

Flex端代码见附件中

Flex+java上传组件1.rar

Flex+java上传组件2rar

 

 

服务端代码是一样的，如下

是用Spring中上传文件实现的

 

UploadServlet.java

 

package com.shop.action.upload;

import java.io.File;
import java.io.IOException;
import java.util.Iterator;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.MultipartHttpServletRequest;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;

public class UploadServlet extends HttpServlet {

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		
		doPost(req, resp);
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		
		saveFile(req,resp);
	}

	public void saveFile(HttpServletRequest request, HttpServletResponse response) 
	throws IllegalStateException, IOException {
	
		
	CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver(request.getSession().getServletContext());
	commonsMultipartResolver.setDefaultEncoding("utf-8");
	
	
	if (commonsMultipartResolver.isMultipart(request)) {  
		MultipartHttpServletRequest multipartRequest = 	commonsMultipartResolver.resolveMultipart(request);  

		Iterator iter = multipartRequest.getFileNames();
		
		String webUrl=request.getSession().getServletContext().getRealPath("/"); //  获取当前程序的路径
		File filePath = new File(webUrl+"uploadDir");   //  拼写成完整的路径
		
	    if (!filePath.exists()) {   
	            filePath.mkdirs();   
	    }  
	     
		for (;iter.hasNext();) {
			MultipartFile file = multipartRequest.getFile((String)iter.next());
			if (file != null) {
				File localFile = new File(file.getOriginalFilename());
				
		        String fileName = filePath + File.separator + file.getOriginalFilename();   //  拼成完整的文件保存路径加文件 
		        file.transferTo(new File(fileName));  //  保存文件到服务器  
		        
			}
		} 
		
		System.out.println("userId: " + request.getParameter("userId"));
	}
}
	

}

 

web.xml配置

   
    <servlet>
     	 <servlet-name>UploadServlet</servlet-name>
     	 <display-name>UploadServlet</display-name>
     	 <servlet-class>com.shop.action.upload.UploadServlet</servlet-class>
     	 <load-on-startup>1</load-on-startup>
     </servlet> 

 <servlet-mapping>
        <servlet-name>UploadServlet</servlet-name>
        <url-pattern>/uploadServlet</url-pattern>
    </servlet-mapping>

首先感谢楼主，另外我这里还有一个问题，服务器端还要加一个commons-io.jar。
