Spring Boot项目中使用HBase2.0.5 Java API操作HBase
最近项目使用到hbase当做数据库存储数据，经过多番网上搜索并把通用方法进行整合，对hbase操作的功能写成了自己的通用方法，现在公布出来希望对大家有所帮助，后期有新的通用功能会实时更新的，通用方法不采用springboot集成的hbase,使用原生java API 操作hbase方法
开发环境
系统：windows
JDK：1.8
开发工具：Intellij IDEA
虚拟机：vmware
三台linux节点： 172.162.15.111、172.162.15.112、172.162.15.113
Linux：CentOS 7 迷你版 CentOS-7-x86_64-Minimal-1708.iso
Hadoop: Hadoop-3.1.2
Hbase : hbase-2.0.5
Zookeeper: zookeeper-3.4.1
第二步：配置windows系统host，根据您的需求，这一步可有可无
#虚拟机访问地址
172.162.15.111 davidone
172.162.15.112 davidtwo
172.162.15.113 davidthree
第三步：项目结构配置pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-client</artifactId>
<version>2.0.5</version>
<exclusions>

<artifactId>log4j</artifactId>
</exclusion>
<exclusion>

</dependency>
application.yml 这个配置以增量的方式添加到文件
logging:
config: classpath:Logback.xml
bigdata:
config:
hBaseConfigMap: {hbase.zookeeper.quorum : 'davidone:2181,davidtwo:2181,davidthree:2181'}
第四步：核心代码
@Component()
@ConfigurationProperties(prefix = "bigdata.config")
public class BigDataConfig {
private Map<String,String> hBaseConfigMap;
public Map<String, String> gethBaseConfigMap() {
return hBaseConfigMap;
}
public void sethBaseConfigMap(Map<String, String> hBaseConfigMap) {
this.hBaseConfigMap = hBaseConfigMap;
}
}
HBaseRepository.java 通用操作hbase数据代码，包含了通用的二级搜索，分页，多条件查询，要求对hbase shell 操作有一定的了解后，能够很好的了解这个通用方法
建议去看下这位博主写的文章：HBase学习笔记
分段进行对HBaseRepository进行展示
4.1、对hbase进行初始化
@Autowired
private BigDataConfig bigDataConfig;
private static Configuration configuration = HBaseConfiguration.create();

private static ExecutorService executorServicePoolSize = Executors.newScheduledThreadPool(20);
private ThreadLocal<Connection> connectionThreadLocal = new ThreadLocal<>();

/**

*/
private void initConfigurationInfo(){
Map<String, String> hBaseConfigMap = bigDataConfig.gethBaseConfigMap();
if(hBaseConfigMap.size() == 0){
logger.debug(MessageFormat.format("HBase配置信息初始化失败：{0}",JSON.toJSONString(hBaseConfigMap)));
}else{
for (Map.Entry<String,String> confEntry : hBaseConfigMap.entrySet()) {

4.2、提取使用到的通用方法

4.3、根据个人需求可以同时创建单张或多张数据表
/**

* @return
*/
public boolean createManyTable(Map<String,List<String>> tableMap){
try{
if(admin != null){

if(admin != null){
return createTable(tableName,Arrays.asList(columnFamily));
}else{

return 0;
}
}catch (Exception e){
logger.debug(MessageFormat.format("创建表失败：{0},错误信息是：{1}",tableName,e.getMessage()));
e.printStackTrace();
return 0;
}finally {
close(admin,null,null);
}
}
4.4、同时添加或更新多列和单列
/**

}
4.5、对hbase 做删除数据或是删除表的操作
/**

4.6、对hbase查询操作 查询条件包含着and 或or 多条件查询，但是没有模糊查询
/**
* 查询所有表名
*/
public List<String> getAllTableNames(){
List<String> resultList = new ArrayList<>();
try {
