For simple CRUD operations, refer to the authoritative guide to HBase (Chinese version). Pdf, the following is the object-oriented encapsulation of HBase basic operations. All DAO layers that use HBase as the storage database inherit the HBaseDaoImpl class. The following is an example of using it.

New operation

Public String add (XControl control) throws Exception {

String id = HBaseRowKeyUtil.getRowKey (controlTableName)

Control.setId (id)

Control.setStatus (Status.ADD.getValue ())

PutDeletepd=HBaseConvetorUtil.convetor (control,id)

Super.savePutDelete (controlTableName, pd)

Return id

Update operation

Public String update (XControl control) throws Exception {

String id = control.getId ()

PutDelete pd=HBaseConvetorUtil.convetor (control,id)

Super.savePutDelete (controlTableName, pd)

Return id

}

Query operation

Public XControl getXControl (String id) throws Exception {

Return super.get (XControl.class,controlTableName, id)

}

Delete operation

Public void delete (String id) throws IOException {

Delete (controlTableName, id)

}
