## 前言 ##

中国地震台数据主要观测的是国内的地震，少量国外等级较高地震，访问太过频繁会被封IP  
美国地震台数据观测全球，有API提供调取，鼓励调取，频繁获取也不会被封IP  
欧洲地震台数据观测全球，采用webscoket的方式接入数据，连接上被动接受数据

### 一、中国地震台网CHN ###

定时获取数据，获取最新一页的地震数据，获取间隔可以设置少一些！

String urlDevicess = "http://www.ceic.ac.cn/ajax/speedsearch?num=2&&page=1";
    String sss = HttpClientUtils.get(urlDevicess);
    JSONObject jsonDevicess = JSON.parseObject(sss.replaceAll("\\(", "").replaceAll("\\)", ""));
    List<Map<String, Object>> deviceListss = (List)jsonDevicess.get("shuju");
    Iterator var5ss = deviceListss.iterator();
    //循环获取数据
    while(var5ss.hasNext()) {
       
        
        Map<String, Object> devicess = (Map)var5ss.next();
        String o_timess = String.valueOf(devicess.get("O_TIME"));//日期
        String LOCATION_Css = String.valueOf(devicess.get("LOCATION_C"));//发生位置
        String Mss = String.valueOf(devicess.get("M"));//震级
        String EPI_LATss = String.valueOf(devicess.get("EPI_LAT"));//纬度
        String EPI_LONss = String.valueOf(devicess.get("EPI_LON"));//经度
        String EPI_DEPTHss = String.valueOf(devicess.get("EPI_DEPTH"));//深度
        //判断数据库是否存在，防止重复入库
        QueryWrapper queryWrapperss = new QueryWrapper();
        queryWrapperss.eq("time", o_timess);
        queryWrapperss.eq("address", LOCATION_Css);
        List<EarthquakeReal> listss = this.EarthquakeRealService.list(queryWrapperss);
    
        //匹配规则：时间差小于3分钟，经纬度小于2度，震级小于0.5级
        if(listss.size() == 0){
       
        
            EarthquakeReal tEarthquakeRealss = new EarthquakeReal();
            tEarthquakeRealss.setGrade(Double.valueOf(Mss));
            tEarthquakeRealss.setTime(o_timess);
            tEarthquakeRealss.setLat(Double.valueOf(EPI_LATss));
            tEarthquakeRealss.setLon(Double.valueOf(EPI_LONss));
            tEarthquakeRealss.setDepth(Double.valueOf(EPI_DEPTHss));
            tEarthquakeRealss.setAddress(LOCATION_Css);
            tEarthquakeRealss.setCreatetime(DateUtil.getTodays("yyyy-MM-dd HH:mm:ss"));
            tEarthquakeRealss.SetCountry("CHN");
            this.EarthquakeRealService.save(tEarthquakeRealss);
        }
    }

### 二、美国地震台网USA ###

根据日期(中国北京时间)经纬度和范围大小获取数据

String today = DateUtil.getToday();
    String urlDevice = "http://earthquake.usgs.gov/fdsnws/event/1/query?format=geojson&latitude=38&longitude=84&maxradiuskm=9999&starttime=" + today;
    String s = HttpClientUtils.get(urlDevice);
    JSONObject jsonDevice = JSON.parseObject(s);
    List<Map<String, Object>> deviceList = (List) jsonDevice.get("features");
    new DecimalFormat("0.");
    Iterator var7 = deviceList.iterator();
     
    while (var7.hasNext()) {
       
        
            Map<String, Object> device = (Map) var7.next();
            JSONObject properties = (JSONObject) device.get("properties");
            JSONObject geometry = (JSONObject) device.get("geometry");
            List<Map<String, Object>> coordinates = (List) geometry.get("coordinates");
            String time = String.valueOf(properties.get("time"));
            String o_time = DateUtil.timeStamp2Date(time, "yyyy-MM-dd HH:mm:ss");
            String LOCATION_C = String.valueOf(properties.get("place"));
            String M = String.valueOf(properties.get("mag"));
            String EPI_LON = String.valueOf(coordinates.get(0));
            String EPI_LAT = String.valueOf(coordinates.get(1));
            String depth = String.valueOf(coordinates.get(2));
    
    
      		EarthquakeReal tEarthquakeReal = new EarthquakeReal();
            tEarthquakeReal.setGrade(Double.valueOf(M));
            tEarthquakeReal.setTime
