Java BufferedReader Download Network files

Use Java BufferedReader to read files from the network to local, to be stored in a database, or to be saved to local Java code

1. Download the contents of the network file into StringBuffer

/**                         从网络地址url下载文件读成字符串 * @param downloadUrl       文件的网络地址 * @return */public static StringBuffer downloadFromUrl(String downloadUrl) {    BufferedReader reader = null;    StringBuffer stringBuffer = new StringBuffer();    String line;    try {        URL url = new URL(downloadUrl);        reader = new BufferedReader(new   InputStreamReader(url.openStream()));        while ((line = reader.readLine()) != null) {            stringBuffer.append(line);        }        return stringBuffer;    } catch (Exception e) {        e.printStackTrace();    } finally {        try {            if (reader != null) {                reader.close();            }        } catch (Exception e) {            e.printStackTrace();        }    }    return null;}

2. Save a string to a file of the specified path

public static void saveAsFile(String content,String fileName) throws FileNotFoundException {    File file=new File(fileName);    PrintStream ps =new PrintStream(new FileOutputStream(file));    ps.append(content);    ps.flush();}
