Hbase  测试工程：

http://192.168.3.221:5000/test/data?webId=10017406

 

 

hbase  表结构分为 ： rowkey、列簇、时间戳、列名、列值

其中 列簇与列名 组合在一起，才是一个hbase中 完整的列名

 

 

（1）

table =(HTable) conn.getTable(TableName.valueOf(tableName));

 

// 按rowkey查找

Get get = newGet(Bytes.toBytes(rowkey));

// 按列族查找

get.addFamily(Bytes.toBytes(columnFamily));

// 查找所有版本

get.setMaxVersions(3);

 

Result dbResult = table.get(get);

 

 

 

（2）

table =(HTable) conn.getTable(TableName.valueOf(tableName));

 

Scan scan = new Scan();

                    

RowFilter filter = newRowFilter(CompareFilter.CompareOp.EQUAL,

              newBinaryComparator(Bytes.toBytes(rowkey)));

          

// 按rowkey查找

scan.setFilter(filter);

// 按列族查找

scan.addFamily(Bytes.toBytes(columnFamily));

scan.addColumn(Bytes.toBytes(columnFamily),Bytes.toBytes("request"));

// 查找所有版本

scan.setMaxVersions();

 

ResultScannerresultScanner = table.getScanner(scan);
