想把双色球历史数据存入数据库。。当时想想挺简单 。可是读从网上读历史记录的时候，发现每次读出来的都不一样。
数据是http://www.17500.cn/getData/ssq.TXT。这里来的。代码
- Java code
public static List<Lorry> readData(){ String url = "http://www.17500.cn/getData/ssq.TXT"; URL u = null; URLConnection conn = null; InputStream is = null; BufferedReader bReader = null; List<Lorry> list = new ArrayList<Lorry>(); String[] line = null; try { u = new URL(url); conn = u.openConnection(); is = conn.getInputStream(); bReader = new BufferedReader(new InputStreamReader(is)); while (bReader.ready()) { Lorry lorry = new Lorry();// line = bReader.readLine().split(" ");// lorry.setMag(line[0]);// lorry.setDate(line[1]);// lorry.setRed1(line[2]);// lorry.setRed2(line[3]);// lorry.setRed3(line[4]);// lorry.setRed4(line[5]);// lorry.setRed5(line[6]);// lorry.setRed6(line[7]);// lorry.setBlue(line[8]);// list.add(lorry); System.out.println(bReader.readLine()); }// for (Lorry l : list) {// System.out.println(l.getDate());// // } } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }finally{ try { is.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } return list;注意每行的第二段开奖时间。控制台显示每次读到的末尾都不一样的。这是为什么啊？
------解决方案--------------------------------------------------------
while (bReader.ready()) {
循环条件不妥，建议用：
String line=null;
while ((line=bReader.readLine()) != null) {
------解决方案--------------------------------------------------------
读取结束判断应是bReader.readLine() != null
------解决方案--------------------------------------------------------
建议使用 Google Guava
- Java code
import com.google.common.io.Resources;List<String> records = Resources.readLines(new URL(url), Charset.forName("GBK"));
