Xml 在本地路径中保存输入流

我试图点击URL并尝试将XML文件保存到本地路径，但我无法做到

我使用的代码在这里

公共类T_save{ 公共静态void下载（字符串地址、字符串localFileName）{ OutputStream out=null； URLConnection conn=null； InputStream in=null

    try {
       URL url = new URL("url");
    //  URL url = new URL(address);
        conn = url.openConnection();
        in = conn.getInputStream();

File File=新文件（地址+本地文件名）；
FileWriter FileWriter=新的FileWriter（文件）；
BufferedReader reader=新的BufferedReader(
新的InputStreamReader（in）；
字符串行=null；
而（（line=reader.readLine（））！=null）{
fileWriter.write（行）；
}
fileWriter.flush（）；
fileWriter.close（）；
}捕获（异常）{
异常。printStackTrace（）；
}最后{
试一试{
if（in！=null）{
in.close（）；
}
if（out！=null）{
out.close（）；
}
}捕获（ioe异常ioe）{
}
}
}
公共静态无效下载（字符串地址）{
int lastSlashIndex=地址.lastIndexOf（'\'）；
如果（lastSlashIndex>=0&&lastSlashIndex

您可以这样做

import java.io.BufferedReader;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.URL;
import java.net.URLConnection;

public class T_save {
    public static void download(String address, String localFileName) {
        OutputStream out = null;
        URLConnection conn = null;
        InputStream in = null;

        try {
            URL url = new URL("http://www.w3schools.com/");
        //  URL url = new URL(address);
            conn = url.openConnection();
            in = conn.getInputStream();

            File file = new File(address+localFileName);
            FileWriter fileWriter = new FileWriter(file);

            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(in));
            String line = null;
            while ((line = reader.readLine()) != null) {
                fileWriter.write(line);
            }
            fileWriter.flush();
            fileWriter.close();

        } catch (Exception exception) {
            exception.printStackTrace();
        } finally {
            try {
                if (in != null) {
                    in.close();
                }
                if (out != null) {
                    out.close();
                }
            } catch (IOException ioe) {
            }
        }
    }

    public static void download(String address) {
        int lastSlashIndex = address.lastIndexOf('/');
        if (lastSlashIndex >= 0 && lastSlashIndex < address.length() - 1) {
            System.out.println(address.substring(0, lastSlashIndex+1)+"\t\t\t"+ address.substring(lastSlashIndex + 1));
            download(address.substring(0, lastSlashIndex+1), address.substring(lastSlashIndex + 1));

        } else {
            System.err.println("Could not figure out local file name for "
                    + address);
        }
    }

    public static void main(String[] args) {

        download("D://output.xml");
        /*
         * for (int i = 0; i < args.length; i++) { download(args[i]); }
         */
    }
}

使用（“\”）作为分隔符，因此发生错误..要解决此问题..有两个选项

1） 您必须在上述程序中替换这一行

int lastSlashIndex=address.lastIndexOf（'/'）

与

int-lastSlashIndex=address.lastIndexOf（'\\'）

或

2） 不要更改上述程序中的任何内容

以（“/”）作为分隔符，像这样传递输入

download("C://Documents and Settings//ocp//output.xml");

它将成功运行

使用此类型的身份验证。。。。下载common-codec1.1.jar（）并将其放置在类路径中

如果您遇到任何问题，请告诉我
是否有其他方法可以将输入流保存到本地路径中的xml文件中？任何其他方法都意味着？？您好，我尝试过，但无法找到的本地文件名“+c:/users/praveen/praveen.xmlHi-naren路径似乎已解决。在包含验证器类之后，我得到了http 401 eror..试图检查出错的地方java.io.IOException:服务器返回了http响应代码：401，URL:URL位于sun.net.www.protocol.http.HttpURLConnection.getInputStream（HttpURLConnection.java:1625）在sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream（Http-sURLConnectionImpl.java:254）在T_save.download（T_save.java:28）在T_save.download（T_save.java:98）在T_save.main（T_save.java:108）运行程序后，我得到上面的错误。。我更新了我正在使用的问题代码检查您的用户名和密码是否正确。。。您在代码中应用身份验证的位置？
