HttpClient4 的使用（post上传文件）struts action 接收

httpclient 4.1 很好的支持了 上传file的功能，下面来看一下具体的代码实现。

package com.whl.httpclient;

import java.io.File;
import java.io.IOException;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;

public class ClientMultipartFormPost {

	public static void main(String[] args) throws ClientProtocolException, IOException {
        
	  HttpClient httpclient = new DefaultHttpClient();
		
	  try {
		    HttpPost httppost = new HttpPost("http://localhost:8080/table!uploadFile");
		
		    FileBody bin = new FileBody(new File("d:/whlwhlwhl.txt"));
		    
		    StringBody comment = new StringBody("just test");
		
		    MultipartEntity reqEntity = new MultipartEntity();
		   
		    reqEntity.addPart("upload", bin);//upload为请求后台的File upload;属性
		    
		    reqEntity.addPart("str", comment);//str 为请求后台的String str;属性
		
		    httppost.setEntity(reqEntity);
		
		    HttpResponse response = httpclient.execute(httppost);
		    
		    int statusCode = response.getStatusLine().getStatusCode();
		    
		    if(statusCode == HttpStatus.SC_OK){
		    	
		    	HttpEntity resEntity = response.getEntity();
		    	
		    	System.out.println(EntityUtils.toString(resEntity));//httpclient自带的工具类读取返回数据
		    
		    	EntityUtils.consume(resEntity);

		    }
		    
		} finally {
		    try { 
		    	httpclient.getConnectionManager().shutdown(); 
		    } catch (Exception ignore) {
		    	
		    }
		}
	}
}

不过如果遇到上传的文件名是中文的名字的话，该如何解决呢？

求解答？
