springboot集成hbase

依赖：

 <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-hadoop-hbase</artifactId>
            <version>2.5.0.RELEASE</version>
        </dependency>
 
        <dependency>
            <groupId>org.apache.hbase</groupId>
            <artifactId>hbase-client</artifactId>
            <version>1.1.2</version>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-hadoop</artifactId>
            <version>2.5.0.RELEASE</version>
        </dependency>

 

 

增加配置

官方提供的方式是通过xml方式，简单改写后如下：

@Configuration
public class HBaseConfiguration {
 
    @Value("${hbase.zookeeper.quorum}")
    private String zookeeperQuorum;
 
    @Value("${hbase.zookeeper.property.clientPort}")
    private String clientPort;
 
    @Value("${zookeeper.znode.parent}")
    private String znodeParent;
 
    @Bean
    public HbaseTemplate hbaseTemplate() {
        org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
        conf.set("hbase.zookeeper.quorum", zookeeperQuorum);
        conf.set("hbase.zookeeper.property.clientPort", clientPort);
        conf.set("zookeeper.znode.parent", znodeParent);
        return new HbaseTemplate(conf);
    }
}

 

 

application.yml：

hbase:
  zookeeper:
    quorum: hadoop001,hadoop002,hadoop003
    property:
      clientPort: 2181
 
zookeeper:
  znode:
    parent: /hbase

 

 

HbaseTemplate test :

@Service
@Slf4j
public class HBaseService {
 
 
    @Autowired
    private HbaseTemplate hbaseTemplate;
 
 
    public List<Result> getRowKeyAndColumn(String tableName, String startRowkey, String stopRowkey, String column, String qualifier) {
        FilterList filterList = new FilterList(FilterList.Operator.MUST_PASS_ALL);
        if (StringUtils.isNotBlank(column)) {
            log.debug("{}", column);
            filterList.addFilter(new FamilyFilter(CompareFilter.CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(column))));
        }
        if (StringUtils.isNotBlank(qualifier)) {
            log.debug("{}", qualifier);
            filterList.addFilter(new QualifierFilter(CompareFilter.CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(qualifier))));
        }
        Scan scan = new Scan();
        if (filterList.getFilters().size() > 0) {
            scan.setFilter(filterList);
        }
        scan.setStartRow(Bytes.toBytes(startRowkey));
        scan.setStopRow(Bytes.toBytes(stopRowkey));
 
        return hbaseTemplate.find(tableName, scan, (rowMapper, rowNum) -> rowMapper);
    }
 
    public List<Result> getListRowkeyData(String tableName, List<String> rowKeys, String familyColumn, String column) {
        return rowKeys.stream().map(rk -> {
            if (StringUtils.isNotBlank(familyColumn)) {
                if (StringUtils.isNotBlank(column)) {
                    return hbaseTemplate.get(tableName, rk, familyColumn, column, (rowMapper, rowNum) -> rowMapper);
                } else {
                    return hbaseTemplate.get(tableName, rk, familyColumn, (rowMapper, rowNum) -> rowMapper);
                }
            }
            return hbaseTemplate.get(tableName, rk, (rowMapper, rowNum) -> rowMapper);
        }).collect(Collectors.toList());
    }
}
