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

import java.io.File;<br /> import java.io.FileNotFoundException;<br /> import java.io.IOException;<br /> import java.io.OutputStream; </p> <p>import org.apache.commons.httpclient.methods.multipart.FilePart;<br /> import org.apache.commons.httpclient.util.EncodingUtil;<br /> /**<br /> *解决中文文件名乱码<br /> */<br /> public class CustomFilePart extends FilePart {<br /> public CustomFilePart(String filename, File file)<br /> throws FileNotFoundException {<br /> super(filename, file);<br /> } </p> <p> protected void sendDispositionHeader(OutputStream out) throws IOException {<br /> super.sendDispositionHeader(out);<br /> String filename = getSource().getFileName();<br /> if (filename != null) {<br /> out.write(EncodingUtil.getAsciiBytes(FILE_NAME));<br /> out.write(QUOTE_BYTES);<br /> out.write(EncodingUtil.getBytes(filename, "utf-8"));<br /> out.write(QUOTE_BYTES);<br /> }<br /> }<br /> }<br />

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