android上传文件

服务器采用ssh架构，其实就是一个action

package action;import java.io.File;import org.apache.commons.io.FileUtils;import com.opensymphony.xwork2.ActionSupport;public class UserAction extends ActionSupport {private static final long serialVersionUID = 1L;private int result;private String msg;private String uploadedPictureFileName;private File uploadedPicture;// --------------------------------------Get And// Set--------------------------------------------------//public int getResult() {return result;}public void setResult(int result) {this.result = result;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public String getUploadedPictureFileName() {return uploadedPictureFileName;}public void setUploadedPictureFileName(String uploadedPictureFileName) {this.uploadedPictureFileName = uploadedPictureFileName;}public File getUploadedPicture() {return uploadedPicture;}public void setUploadedPicture(File uploadedPicture) {this.uploadedPicture = uploadedPicture;}// --------------------------------------Method--------------------------------------------------//public String receiveFile() throws Exception {File f = new File("f:\\" + getUploadedPictureFileName());System.out.println("f:\\" + getUploadedPictureFileName());FileUtils.copyFile(getUploadedPicture(), f);return null;}}

android端，首先选择一个图片或者录音或者视频，在选择完毕的时候会上传到服务器中。

附件为android代码，服务器则自己搭建。
