struts2下载中文名文件问题

action：
public class DownloadAction extends ActionSupport {
private String fileName;

public String getDownloadFileName() {
String fileName=ServletActionContext.getRequest().getParameter("fileName");
String downFileName = fileName;
try {
downFileName = new String(downFileName.getBytes("ISO-8859-1"), "UTF-8");
} catch (Exception e) {
e.printStackTrace();
}
return downFileName;
}

public InputStream getInputStream() {
String name=this.getDownloadFileName();
String realPath="/upload/"+name;
InputStream in=ServletActionContext.getServletContext().getResourceAsStream(realPath);
System.out.println(in);
if(null==in){
System.out.println("Can not find a java.io.InputStream with the name [inputStream] in the invocation stack. Check the <param name=\"inputName\"> tag specified for this action.检查action中文件下载路径是否正确.");
}
return ServletActionContext.getServletContext().getResourceAsStream(realPath);
}
@Override
public String execute() throws Exception {
return "SUCCESS";
}
public String getFileName() {
return fileName;
}
public void setFileName(String fileName) {
this.fileName = fileName;
}

struts：<action name="download" class="com.file.action.DownloadAction">
<result name="SUCCESS" type="stream">
<param name="contentType">application/octet-stream;
</param>
<param name="contentDisposition">
attachment;filename="${downFileName}"
</param>
<param name="inputName">inputStream</param>
<param name="bufferSize">4096</param>
</result>
</action>
下载时弹出框显示文件名是download.action,要怎么才能显示中文原名呢

Answer 1

downFileName = new String(downFileName.getBytes("ISO-8859-1"), "UTF-8");

系统是使用ISO-8859-1编码的？那中文肯定筹码了。

统一使用GBK、或UTF-8编码

追问

系统页面用的UTF-8，但是这里不知道怎么改啊，总是不对啊

追答

那还由iso-8859-1转成UTF8，是UTF8就不用转了

追问

没用啊，还是不行啊，只有一开始的那个时候才能下载，但是弹出下载框上文件名是download.action，不能显示中文啊

Answer 2

public String getDownloadFileName() {
String downFileName=URLEncoder.encode(fileName,"utf-8")
return downFileName;
}

追问

谢谢，可是还是没用
