发送XML文件作为Java的附件

Question

我想在URL从Java类

代码发送XML文件作为附件与我试图为如下

File request_XML_file = new File("src/request.xml");  
      URL url = new URL("https://************?p_xml_file="+request_XML_file); 
      conn = (HttpURLConnection) url.openConnection(); 
      conn.setRequestMethod("POST"); 
      conn.setRequestProperty("enctype","multipart/form-data"); 

但值传递的p_xml_file为src /request.xml

你也可以考虑的Java 7的新功能

Path path = Paths.get("/tmp/foo/bar.txt"); Files.createDirectories(path.getParent()); try { Files.createFile(path); } catch (FileAlreadyExistsException e) { System.err.println("already exists: " + e.getMessage()); } } }
