推荐答案

最简单的方式是使用常规的文件路径来读取。

The simplest way to do this would be to read it using regular file paths.

在Windows上：

On Windows:

new File("\\\\server\\path\\to\\file.txt")
// (double-backslashes required for backslashes in path)

在Unix上：

首先使用Samba（SMB，NFS或任何其他协议）将共享安装到某些位置，如/ mnt / network。然后你可以使用：

First mount the share using Samba (SMB, NFS or whatever other protocol) to some location like /mnt/network. Then you can use:

new File("/mnt/network/path/to/file.txt")

Once you have the File object you can use FileInputStream, FileReader or whatever else you want to read the file in.

编辑以供评论回复。如果您使用的是Applet，则可能需要从Web服务器中拉取文件。您可以使用内置的java.net.URL类，但如果您不仅要做简单的事情，我会推荐这样做： http://hc.apache.org/httpclient-3.x/index.html

Edit for comments response. If you are using an Applet, you probably want to pull the file from a web server. You can use the built in java.net.URL class but I would recommend this if you have to do more than just simple stuff: http://hc.apache.org/httpclient-3.x/index.html

示例（from Commons HTTP Site）：

Example (from the Commons HTTP Site):

    // Create an instance of HttpClient.
    HttpClient client = new HttpClient();

    // Create a method instance.
    GetMethod method = new GetMethod(url);

    try {
      // Execute the method.
      int statusCode = client.executeMethod(method);

      if (statusCode != HttpStatus.SC_OK) {
        System.err.println("Method failed: " + method.getStatusLine());
      }

      // Read the response body.
      byte[] responseBody = method.getResponseBody();

      // Deal with the response.
      // Use caution: ensure correct character encoding and is not binary data
      System.out.println(new String(responseBody));

    } catch (HttpException e) {
      System.err.println("Fatal protocol violation: " + e.getMessage());
      e.printStackTrace();
    } catch (IOException e) {
      System.err.println("Fatal transport error: " + e.getMessage());
      e.printStackTrace();
    } finally {
      // Release the connection.
      method.releaseConnection();
    }  
  }
}
