这篇文章主要介绍了基于springboot集成hbase过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
springboot-habse:
https://github.com/spring-projects/spring-hadoop-samples/tree/master/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：
@Configurationpublic 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@Slf4jpublic 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()); }}
