JSP开发之Struts2实现下载功能的实例

1、Action 类

package com.favccxx.strutsdemo; 
 
import java.io.File; 
import java.io.FileInputStream; 
import java.io.InputStream; 
 
import com.opensymphony.xwork2.ActionSupport; 
 
public class DownloadAction extends ActionSupport { 
 
   
  private static final long serialVersionUID = -7758584364932001138L; 
   
  private InputStream inputStream; 
 
  @Override 
  public String execute() throws Exception { 
     inputStream = new FileInputStream(new File("D:\\芒果豆.jpg")); 
     return SUCCESS; 
  } 
 
  public InputStream getInputStream() { 
    return inputStream; 
  } 
 
  public void setInputStream(InputStream inputStream) { 
    this.inputStream = inputStream; 
  } 
   
   
 
} 

2、struts.xml

        HelloWorld 
        /example
