import java.io.FileInputStream;
import java.io.FileOutputStream;

import java.io.OutputStream;

import org.apache.struts2.ServletActionContext;

*/

// myFile属性用来封装上传的文件
private File myFile;

// myFileContentType属性用来封装上传文件的类型
private String myFileContentType;

// myFileFileName属性用来封装上传文件的文件名
private String myFileFileName;

//获得myFile值
public File getMyFile() {

}

//设置myFile值
public void setMyFile(File myFile) {
this.myFile = myFile;

//获得myFileContentType值
public String getMyFileContentType() {

}

//设置myFileFileName值
public void setMyFileFileName(String myFileFileName) {

}

public String execute() throws Exception {

//基于myFile创建一个文件输入流
InputStream is = new FileInputStream(myFile);

// 设置上传文件目录
String uploadPath = ServletActionContext.getServletContext()
.getRealPath("/upload");

// 设置目标文件
File toFile = new File(uploadPath, this.getMyFileFileName());

// 创建一个输出流
OutputStream os = new FileOutputStream(toFile);

//设置缓存
byte[] buffer = new byte[1024];

int length = 0;

//读取myFile文件输出到toFile文件中
while ((length = is.read(buffer)) > 0) {

}

//关闭输入流
is.close();

//关闭输出流
os.close();
