Hbase+Phoenix+Mybatis+Springboot如何進(jìn)行整合查詢數(shù)據(jù)

這篇文章給大家介紹Hbase+Phoenix+Mybatis+Springboot如何進(jìn)行整合查詢數(shù)據(jù)，內(nèi)容非常詳細(xì)，感興趣的小伙伴們可以參考借鑒，希望對(duì)大家能有所幫助。

Phoenix Query Server提供了一種與Phoenix和HBase交互的替代方法。很快，這將允許從JVM以外的環(huán)境進(jìn)行訪問。

• 在4.x和5.0版本中，查詢服務(wù)器及其JDBC客戶端是標(biāo)準(zhǔn)Phoenix發(fā)行版的一部分。它們不需要其他依賴項(xiàng)。

• 在5.0版本之后，查詢服務(wù)器已被捆綁到phoenix-queryserver存儲(chǔ)庫(kù)中，并且其版本號(hào)已重置為1.0。在撰寫本文時(shí)，沒有獨(dú)立查詢服務(wù)器的發(fā)行版本。

由于我們安裝的是apache-phoenix-5.0.0-HBase-2.0,所以里面內(nèi)置了queryserver

1.啟動(dòng)queryserver,默認(rèn)監(jiān)聽8765

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

2.自定義配置 vim hbase-site.xml

//將默認(rèn)的8765端口改成8888
<property>
  <name>phoenix\.queryserver\.http\.port</name>
  <value>8888</value>
</property>

3.pom.xml中引入Phoenix客戶端

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

5.數(shù)據(jù)源配置

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(shè)置Phoenix驅(qū)動(dòng)
        druidDataSource.setDriverClassName(Driver.class.getName());
        druidDataSource.setUrl(dataSourceProperties.getUrl());
        return druidDataSource;
    }
}

6.數(shù)據(jù)庫(kù)操作類UserMapper

注意:由于我的HBase數(shù)據(jù)庫(kù)表名和字段名都是小寫所以我這里表名和字段名必須加上雙引號(hào),否則表名和字段名會(huì)變成大寫，找不到對(duì)應(yīng)關(guān)系，會(huì)報(bào)錯(cuò)。

如果HBase數(shù)據(jù)庫(kù)中表名和字段名都是大寫，那么則不需要雙引號(hào)

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(hào),否則表名和字段名會(huì)變成大寫，找不到對(duì)應(yīng)關(guān)系，會(huì)報(bào)錯(cuò)
    @Select("select * from \"test2\" where \"id\"=#{id}")
    User selectById(Integer id);
}

7.實(shí)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}
