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

[java] view
plaincopy

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();

}



[java] view
plaincopy

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;

/**

*解决中文文件名乱码

*/

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：

[java] view
plaincopy

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");
