SpringBoot系列---【springboot集成phoenix调用hbase】

springboot集成phoenix调用hbase

1.环境

• jdk8
• hbase-2.1.0

2.新建springboot，添加pom依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                    <excludes>
                        <exclude>

            </plugin>
        </plugins>
    </build>
</project>

3.配置application.yml

server:
  port: 8080
spring:
  datasource:
    driver-class-name: org.apache.phoenix.jdbc.PhoenixDriver
    url: jdbc:phoenix:afp-dev-bigdata1,afp-dev-bigdata2,afp-dev-bigdata3:2181/hbase
mybatis-plus:
  mapper-locations: classpath*:com/demo/mapper/*.xml
  type-aliases-package: com.demo.entity

4.添加hbase-site.xml配置

<?xml version="1.0" ?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <property>
        <name>phoenix.schema.isNamespaceMappingEnabled</name>
        <value>true</value>
    </property>
    <property>
        <name>phoenix.schema.mapSystemTablesToNamespace</name>
        <value>true</value>
    </property>
</configuration>

5.新建entity实体类

package com.demo.entity;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;

@Data
@TableName("US_POPULATION")
public class UsPopulation {

    @TableId(type = IdType.INPUT,value = "ROWKEY")
    private String rowkey;

    @TableField("CF.STATE")
    private String state;

    @TableField("CF.CITY")
    private String city;

    @TableField("CF.POPULATION")
    private long population;
}

6.新建UsPopulationMapper.java类

package com.demo.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.demo.entity.UsPopulation;

import java.util.List;

public interface UsPopulationMapper extends BaseMapper<UsPopulation> {

    List<UsPopulation> queryAll();
}

7.新建UsPopulationMapper.xml类

放到classpath下的com.demo.mapper包下

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.demo.mapper.UsPopulationMapper">
    <select id="queryAll" resultType="com.demo.entity.UsPopulation">
        select * from US_POPULATION
    </select>
</mapper>

8.新建UsPopulationServiceImpl.java

package com.demo.service;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.demo.entity.UsPopulation;
import com.demo.mapper.UsPopulationMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;

@Service
public class UsPopulationServiceImpl extends ServiceImpl<UsPopulationMapper,UsPopulation> implements  UsPopulationService{
    @Autowired
    private UsPopulationMapper usPopulationMapper;

    @Override
    public List<UsPopulation> findAll() {
        return usPopulationMapper.queryAll();
    }
}

9.新建UsPopulationService.java

package com.demo.service;

import com.baomidou.mybatisplus.extension.service.IService;
import com.demo.entity.UsPopulation;
import java.util.List;

public interface UsPopulationService extends IService<UsPopulation> {
    List<UsPopulation> findAll();
}

10.新建TestController.java

package com.demo.controller;

import com.demo.entity.UsPopulation;
import com.demo.service.UsPopulationService;
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;
import java.util.List;

@RestController
@RequestMapping("test")
public class TestController {
    @Autowired
    private UsPopulationService usPopulationService;

    @GetMapping("findAll")
    public List<UsPopulation> findAll(){
        return usPopulationService.findAll();
    }

    @GetMapping("selectList")
    public List<UsPopulation> list(){
        return usPopulationService.list();
    }
}
