解决HttpClient的FilePart上传文件中使用中文名称文件名乱码问题

 String targetUrl = "http://localhost:8080/Test";
     PostMethod filePost = new PostMethod(targetUrl) {//这个用来中文乱码
             public String getRequestCharSet() {
                     return "UTF-8";//
                 }
     };
     try {
                 HttpClient client = new HttpClient();
                 File file = new File("c:/新闻.xml");
                 Part[] parts = new Part[] {new CustomFilePart(file.getName(), file)};
                 filePost.setRequestEntity(new MultipartRequestEntity(parts, filePost.getParams()));
                 int statuscode=client.executeMethod(filePost);
                 if(statuscode == HttpStatus.SC_OK) {
 System.out.println("添加文件成功");
 } else {
 System.out.println("添加文件失败");
 }
 } catch (Exception ex) {
 ex.printStackTrace();
 }

 

 import java.io.File;
 import java.io.FileNotFoundException;
 import java.io.IOException;
 import java.io.OutputStream;

 import org.apache.commons.httpclient.methods.multipart.FilePart;
 import org.apache.commons.httpclient.util.EncodingUtil;
 /**

 public class CustomFilePart extends FilePart {
     public CustomFilePart(String filename, File file)
             throws FileNotFoundException {
         super(filename, file);
     }

     protected void sendDispositionHeader(OutputStream out) throws IOException {
         super.sendDispositionHeader(out);
         String filename = getSource().getFileName();
         if (filename != null) {
             out.write(EncodingUtil.getAsciiBytes(FILE_NAME));
             out.write(QUOTE_BYTES);
             out.write(EncodingUtil.getBytes(filename, "utf-8"));
             out.write(QUOTE_BYTES);
         }
     }
 }

 

而服务端使用apache的commonfileupload：

 File tempfile = new File(System.getProperty("java.io.tmpdir")); // 采用系统临时文件目录
             DiskFileItemFactory diskFileItemFactory = new DiskFileItemFactory();
             diskFileItemFactory.setSizeThreshold(4096); // 设置缓冲区大小，这里是4kb
             diskFileItemFactory.setRepository(tempfile); // 设置缓冲区目录
             ServletFileUpload fu = new ServletFileUpload(diskFileItemFactory);
             fu.setSizeMax(4194304); // 限制文件大小最大为4M
             List fileItems = fu.parseRequest(request);
             Iterator i = fileItems.iterator();
             while (i.hasNext()) {
                 FileItem fi = (FileItem) i.next();
                 String fileName = fi.getName();
                 if (fileName != null) {
                     File fullFile = new File(fi.getName());
                     File savedFile = new File(uploadPath, fullFile.getName());
                     fi.write(savedFile);
                 }
             }
             System.out.println("upload succeed");
