服务端

import java.io.InputStream;



import javax.servlet.http.HttpServletRequest;



import org.apache.struts2.ServletActionContext;



import com.opensymphony.xwork2.Action;

public class GetFileAction extends ActionSupport {



    private static final long serialVersionUID = -9108080625441081032L;  

    public String execute() throws Exception   

    {       

        String rootPath = PropertyUtil.getProperty("fileSys.properties","fileSys.path");

        

        HttpServletRequest request = ServletActionContext.getRequest();

        String filePath = request.getParameter("filePath");

        String fileName = request.getParameter("fileName");



        InputStream input = request.getInputStream(); 

        String fileFullPath = rootPath + filePath + fileName; 

        

        File file = new File(rootPath + filePath);

        if(!file.exists()){

            file.mkdirs();

        }

        FileOutputStream fos = new FileOutputStream(fileFullPath);



        int size = 0;

        byte[] buffer = new byte[1024];

            fos.write(buffer, 0, size);

如果用jersey,形成RESTfull webservices 就更有用了
