Hbase+Phoenix+Mybatis+Springboot整合查詢數據

Phoenix Query Server提供了一種與Phoenix和HBase交互的替代方法。很快，這將容許從JVM之外的環境進行訪問。java

在4.x和5.0版本中，查詢服務器及其JDBC客戶端是標準Phoenix發行版的一部分。它們不須要其餘依賴項。mysql
在5.0版本以後，查詢服務器已被捆綁到phoenix-queryserver存儲庫中，而且其版本號已重置爲1.0。在撰寫本文時，沒有獨立查詢服務器的發行版本。git

因爲咱們安裝的是apache-phoenix-5.0.0-HBase-2.0,因此裏面內置了queryservergithub

1.啓動queryserver,默認監聽8765web

> apache-phoenix-5.0.0-HBase-2.0-bin/bin/queryserver.py

2.自定義配置 vim hbase-site.xmlspring

屬性	描述	默認
phoenix.queryserver.http.port	指定服務器將偵聽的端口。默認值爲8765。	8765
phoenix.queryserver.metafactory.class	要實例化的Avatica Meta.Factory類。	org.apache.phoenix.queryserver.server.PhoenixMetaFactoryImpl
phoenix.queryserver.serialization	傳輸/序列化格式，PROTOBUF或JSON。	PROTOBUF

//將默認的8765端口改爲8888
<property>
  <name>phoenix\.queryserver\.http\.port</name>
  <value>8888</value>
</property>

3.pom.xml中引入Phoenix客戶端sql

//輕量級客戶端
<dependency>
  <groupId>org.apache.phoenix</groupId>
  <artifactId>phoenix-queryserver-client</artifactId>
  <version>5.0.0-HBase-2.0</version>
</dependency>

4.完整的pom.xml數據庫

    </build>

</project>

5.數據源配置apache

package com.rumenz.phoenix;

import com.alibaba.druid.pool.DruidDataSource;
import org.apache.phoenix.queryserver.client.Driver;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

@Configuration
@MapperScan(basePackages = "com.rumenz.phoenix.mapper")
public class PhoenixForMybatisConfiguration {

    @Autowired
    private DataSourceProperties dataSourceProperties;

    @Bean
    public DataSource phoenixDataSource() {
        DruidDataSource druidDataSource = new DruidDataSource();
        //設置Phoenix驅動
        druidDataSource.setDriverClassName(Driver.class.getName());
        druidDataSource.setUrl(dataSourceProperties.getUrl());
        return druidDataSource;
    }
}

6.數據庫操做類UserMappervim

注意:因爲個人HBase數據庫表名和字段名都是小寫因此我這裏表名和字段名必須加上雙引號,不然表名和字段名會變成大寫，找不到對應關係，會報錯。

若是HBase數據庫中表名和字段名都是大寫，那麼則不須要雙引號

package com.rumenz.phoenix.mapper;

import com.rumenz.phoenix.entity.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;

@Mapper
public interface UserMapper {
    //表名和字段名必須加上雙引號,不然表名和字段名會變成大寫，找不到對應關係，會報錯
    @Select("select * from \"test2\" where \"id\"=#{id}")
    User selectById(Integer id);
}

7.實體類

package com.rumenz.phoenix.entity;

public class User {
     private Integer id;
     private String  name;
     private Integer age;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

8.訪問控制UserController

package com.rumenz.phoenix.controller;


import com.rumenz.phoenix.entity.User;
import com.rumenz.phoenix.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/user/")
public class UserController {

    @Autowired
    private UserMapper userMapper;

    @GetMapping("index")
    public String index(){
        User user = userMapper.selectById(1);
        return user.toString();
    }
}

9.訪問http://127.0.0.1:8080/user/index

User{id=1, name='rumenz', age=30}
