吴超老师课程--HBASE的查询手机项目

查询
1.按RowKey查询
2.按手机号码查询
3.按手机号码的区域查询

 1 //查询手机13450456688的所有上网记录
 2     public static void scan(String tableName) throws IOException{
 3         HTable table = new HTable(getConfiguration(), tableName);
 4         Scan scan = new Scan();
 5         scan.setStartRow(Bytes.toBytes("13450456688:/"));
 6         scan.setStopRow(Bytes.toBytes("13450456688::"));
 7         ResultScanner scanner = table.getScanner(scan);
 8         int i=0;
 9         for (Result result : scanner) {
10             System.out.println("Scan: "+i+++" "+result);
11         }
12     }

 1 //查询134号段的所有上网记录
 2 public static void scanPeriod(String tableName) throws IOException{
 3         HTable table = new HTable(getConfiguration(), tableName);
 4         Scan scan = new Scan();
 5         scan.setStartRow(Bytes.toBytes("134/"));
 6         scan.setStopRow( Bytes.toBytes("134:"));
 7         scan.setMaxVersions(1);
 8         ResultScanner scanner = table.getScanner(scan);
 9         int i=0;
10         for (Result result : scanner) {
11             System.out.println("Scan: "+i+++" "+result);
12         }
13     }
