We thought the concert in the park would be popular but we didn’t anticipate so many people to turn up so early.
The research findings show that children normally feel a lot of anxiety about their first day at school.
如下在打印时，例如列簇若不加（）就会打印出来乱码，乱码的原因是由于在底层，没有找准相关参数的位置，通过这两个方法（即偏移量的处理）就能精准的定位。public void get2() throws IOException {//1. 创建get对象Get get = new Get(Bytes.toBytes("001"));//2. 查询数据，返回结果对象Result result = table.get(get);//3. 获取cell的扫描器CellScanner cellScanner = result.cellScanner();//4. 遍历扫描器while(cellScanner.advance()) {//5. 获取单词扫描的CellCell cell = cellScanner.current();System.out.println(new String(cell.getFamilyArray(),cell.getFamilyOffset(), cell.getFamilyLength())); // 列簇System.out.println(new String(cell.getQualifierArray(), cell.getQualifierOffset(), cell.getQualifierLength())); // 列名System.out.println(new String(cell.getValueArray(), cell.getValueOffset(), cell.getValueLength())); // 列值}}
这里在打印时用了CellUtil.cloneFamily(cell)方法后，我们不需要自己去指定它的偏移量和长度，原因是CellUtil.cloneFamily(cell)方法中包含了（）两个方法的功能，以免打印出来乱码，由于在底层，没有找准相关参数的位置，通过这个方法（即偏移量的处理）就能精准的定位。public void get3() throws IOException {//1. 创建get对象Get get = new Get(Bytes.toBytes("001"));//2. 查询数据，返回结果对象Result result = table.get(get);//3. 获取cell的扫描器CellScanner cellScanner = result.cellScanner();//4. 遍历扫描器while(cellScanner.advance()) {//5. 获取单词扫描的CellCell cell = cellScanner.current();System.out.println(new String(CellUtil.cloneRow(cell))); // 行键System.out.println(new String(CellUtil.cloneFamily(cell))); // 列簇System.out.println(new String(CellUtil.cloneQualifier(cell))); // 列名System.out.println(new String(CellUtil.cloneValue(cell))); // 列值}}
