在客户端的上述代码中，getText（）函数从本地目录中读取文件。我需要从服务器计算机加载文件，我该怎么办。我使用java spring概念进行客户端服务器通信。任何机会在xml bean文件中加载资源。请发布一些使用完整代码

如何从URL读取文件？像

这样的东西

URL theFile = new URL("http://www.foobar.com/thefile.txt");

打开一个内流

BufferedReader in = new BufferedReader(new InputStreamReader(theFile.openStream()));

将其内容写入文件。

FileWriter fWriter= new FileWriter(file_name);
BufferedWriter out = new BufferedWriter(fWriter);
out.write(in.readLine());

礼貌。

out.close();
in.close();

Finitio！
