02数据生成

    一切配置外部文件化。

    创建gendata.conf

log.file=/home/centos/calllog/calllog.log

call.duration.max=600 

call.duration.format=000

call.year=2017

call.time.format=yyyy/MM/dd HH:mm:ss

gen.data.interval.ms=2000

创建PropertiesUtil类，用于读取gendata.conf 中的配置

    

public class PropertiesUtil {

    static Properties prop ;
    static{
        try {
            InputStream in = ClassLoader.getSystemResourceAsStream("gendata.conf");
            prop = new Properties();
            prop.load(in);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static String getProp(String key){
        return prop.getProperty(key) ;
    }

    public static String getString(String key){
        return prop.getProperty(key) ;
    }

    public static int getInt(String key){
        return Integer.parseInt(prop.getProperty(key)) ;
    }
}

创建GenDataAppMain类：

public class GenDataAppMain {
    static Random r = new Random();

    public static List<String> phoneNumbers = new ArrayList<String>();
    
    public static Map<String,String> callers = new HashMap<String, String>();
    static{

        callers.put("15220141678", "陈一");
        callers.put("18046865067", "胡二");
        callers.put("15119884501", "张三 ");
        callers.put("19263361219", "李四");
        callers.put("18032291306", "王五");
        callers.put("12711058869", "任六");
        callers.put("15335593369", "梁七");
        callers.put("12734214050", "刘八");
        callers.put("14618206525", "朱九");
        callers.put("17781348030", "郭十");
        callers.put("18646281129", "邵十一");
        callers.put("15031645440", "黎十二");
        callers.put("13041909505", "肖十三");
        callers.put("13664192665", "杨十四");
        callers.put("18404589132", "骆十五");
        callers.put("13920504953", "郑十六");
        callers.put("18532662075", "黄十七");
        callers.put("18120592721", "罗十八");
        phoneNumbers.addAll(callers.keySet());
    }



    public static void main(String[] args) throws Exception {
        genCallLog();
    }

    public static void genCallLog() throws Exception {
//        FileWriter fw = new FileWriter("/home/centos/calllog/calllog.log",true);
        FileWriter fw = new FileWriter(PropertiesUtil.getString("log.file"),true);
        while(true){
            //取主叫
            String caller = phoneNumbers.get(r.nextInt(callers.size()));
            //主叫名字
            String callerName = callers.get(caller);

            //被叫号
            String callee = null;
            String calleeName = null;
            while (true) {
                callee = phoneNumbers.get(r.nextInt(callers.size()));
                if (!caller.equals(callee)) {
                    break;
                }
            }
            calleeName = callers.get(callee);
            //通话时长
            int duration = r.nextInt(PropertiesUtil.getInt("call.duration.max")) + 1;
            DecimalFormat df = new DecimalFormat();
            df.applyPattern(PropertiesUtil.getString("call.duration.format"));
            String durStr = df.format(duration);

            //通话时间
            int year = PropertiesUtil.getInt("call.year");
            //月份(0~11)
            int month = r.nextInt(12);
            //天,范围(1~31)
            int day = r.nextInt(29) + 1;
            int hour = r.nextInt(24);
            int min = r.nextInt(60);
            int sec = r.nextInt(60);

            Calendar c = Calendar.getInstance();
            c.set(Calendar.YEAR, year);
            c.set(Calendar.MONTH, month);
            c.set(Calendar.DAY_OF_MONTH, day);
            c.set(Calendar.HOUR_OF_DAY, hour);
            c.set(Calendar.MINUTE, min);
            c.set(Calendar.SECOND, sec);
            Date date = c.getTime();


            //如果时间超过今天就重新qushijian取时间.
            Date now = new Date();
            if (date.compareTo(now) > 0) {
                continue ;
            }
            SimpleDateFormat dfs = new SimpleDateFormat();
            dfs.applyPattern(PropertiesUtil.getString("call.time.format"));
            //通话时间
            String dateStr = dfs.format(date);

            //String log = caller + "," + callerName + "," + callee + "," + calleeName + "," + dateStr + "," + durStr  ;
            String log = caller + "," + callee + "," + dateStr + "," + durStr;
            System.out.println(log);
            fw.write(log + "\r\n");
            fw.flush();
            Thread.sleep(PropertiesUtil.getInt("gen.data.interval.ms"));
        }
    }
 }

打成jar包仍到s128：

事先要创建好calllog.sh脚本：

运行脚本：

数据生成到calllog.log文件
