Spring/Spring Boot 整合 Mybatis + Phoenix | 来唧唧歪歪(Ljjyy.com)

一、前言

使用Spring+Mybatis操作Phoenix和操作其他的关系型数据库（如Mysql，Oracle）在配置上是基本相同的，下面会分别给出Spring/Spring Boot 整合步骤，完整代码见本仓库：

二、Spring + Mybatis + Phoenix

2.1 项目结构

2.2 主要依赖

除了Spring相关依赖外，还需要导入phoenix-core和对应的Mybatis依赖包

<!--mybatis 依赖包-->
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.3.2</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.4.6</version>
</dependency>
<!--phoenix core-->
<dependency>
    <groupId>org.apache.phoenix</groupId>
    <artifactId>phoenix-core</artifactId>
    <version>4.14.0-cdh5.14.2</version>
</dependency>

2.3 数据库配置文件

在数据库配置文件 jdbc.properties 中配置数据库驱动和zookeeper地址

# 数据库驱动
phoenix.driverClassName=org.apache.phoenix.jdbc.PhoenixDriver
# zookeeper地址
phoenix.url=jdbc:phoenix:192.168.0.105:2181

2.4 配置数据源和会话工厂

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 开启注解包扫描-->
    <context:component-scan base-package="com.myhhub.*"/>

    <!--指定配置文件的位置-->
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!--配置数据源-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <!--Phoenix配置-->
        <property name="driverClassName" value="${phoenix.driverClassName}"/>
        <property name="url" value="${phoenix.url}"/>
    </bean>

    <!--配置 mybatis 会话工厂 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--指定mapper文件所在的位置-->
        <property name="mapperLocations" value="classpath*:/mappers/**/*.xml"/>
        <property name="configLocation" value="classpath:mybatisConfig.xml"/>
    </bean>

    <!--扫描注册接口 -->
    <!--作用:从接口的基础包开始递归搜索，并将它们注册为 MapperFactoryBean(只有至少一种方法的接口才会被注册;, 具体类将被忽略)-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--指定会话工厂 -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 指定mybatis接口所在的包 -->
        <property name="basePackage" value="com.myhhub.dao"/>
    </bean>

</beans>

2.5 Mybtais参数配置

新建mybtais配置文件，按照需求配置额外参数，更多settings配置项可以参考官方文档

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

<!-- mybatis 配置文件 -->
<configuration>
    <settings>
        <!-- 开启驼峰命名 -->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <!-- 打印查询sql -->
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>
</configuration>

2.6 查询接口

public interface PopulationDao {

    List<USPopulation> queryAll();

    void save(USPopulation USPopulation);

    USPopulation queryByStateAndCity(@Param("state") String state, @Param("city") String city);

    void deleteByStateAndCity(@Param("state") String state, @Param("city") String city);
}

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.myhhub.dao.PopulationDao">


    <select id="queryAll" resultType="com.myhhub.bean.USPopulation">
        SELECT * FROM us_population
    </select>

    <insert id="save">
        UPSERT INTO us_population VALUES( #{state}, #{city}, #{population} )
    </insert>

    <select id="queryByStateAndCity" resultType="com.myhhub.bean.USPopulation">
        SELECT * FROM us_population WHERE state=#{state} AND city = #{city}
    </select>

    <delete id="deleteByStateAndCity">
        DELETE FROM us_population WHERE state=#{state} AND city = #{city}
    </delete>

</mapper>

2.7 单元测试

@RunWith(SpringRunner.class)
@ContextConfiguration({"classpath:springApplication.xml"})
public class PopulationDaoTest {

    @Autowired
    private PopulationDao populationDao;

    @Test
    public void queryAll() {
        List<USPopulation> USPopulationList = populationDao.queryAll();
        if (USPopulationList != null) {
            for (USPopulation USPopulation : USPopulationList) {
                System.out.println(USPopulation.getCity() + " " + USPopulation.getPopulation());
            }
        }
    }

    @Test
    public void save() {
        populationDao.save(new USPopulation("TX", "Dallas", 66666));
        USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
        System.out.println(usPopulation);
    }

    @Test
    public void update() {
        populationDao.save(new USPopulation("TX", "Dallas", 99999));
        USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
        System.out.println(usPopulation);
    }


    @Test
    public void delete() {
        populationDao.deleteByStateAndCity("TX", "Dallas");
        USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
        System.out.println(usPopulation);
    }
}

三、SpringBoot + Mybatis + Phoenix

3.1 项目结构

3.2 主要依赖

<!--spring 1.5 x 以上版本对应 mybatis 1.3.x (1.3.1)
        关于更多spring-boot 与 mybatis 的版本对应可以参见 <a href="http://www.mybatis.org/spring-boot-starter/mybatis-spring-boot-autoconfigure/">-->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.3.2</version>
</dependency>
<!--phoenix core-->
<dependency>
    <groupId>org.apache.phoenix</groupId>
    <artifactId>phoenix-core</artifactId>
    <version>4.14.0-cdh5.14.2</version>
</dependency>
<dependency>

spring boot 与 mybatis 版本的对应关系：

MyBatis-Spring-Boot-Starter 版本	MyBatis-Spring 版本	Spring Boot 版本
1.3.x (1.3.1)	1.3 or higher	1.5 or higher
1.2.x (1.2.1)	1.3 or higher	1.4 or higher
1.1.x (1.1.1)	1.3 or higher	1.3 or higher
1.0.x (1.0.2)	1.2 or higher	1.3 or higher

3.3 配置数据源

在application.yml 中配置数据源，spring boot 2.x 版本默认采用Hikari作为数据库连接池，Hikari是目前java平台性能最好的连接池，性能好于druid。

spring:
  datasource:
    #zookeeper地址
    url: jdbc:phoenix:192.168.0.105:2181
    driver-class-name: org.apache.phoenix.jdbc.PhoenixDriver

    # 如果不想配置对数据库连接池做特殊配置的话,以下关于连接池的配置就不是必须的
    # spring-boot 2.X 默认采用高性能的 Hikari 作为连接池 更多配置可以参考 https://github.com/brettwooldridge/HikariCP#configuration-knobs-baby
    type: com.zaxxer.hikari.HikariDataSource
    hikari:
      # 池中维护的最小空闲连接数
      minimum-idle: 10
      # 池中最大连接数，包括闲置和使用中的连接
      maximum-pool-size: 20
      # 此属性控制从池返回的连接的默认自动提交行为。默认为true
      auto-commit: true
      # 允许最长空闲时间
      idle-timeout: 30000
      # 此属性表示连接池的用户定义名称，主要显示在日志记录和JMX管理控制台中，以标识池和池配置。 默认值：自动生成
      pool-name: custom-hikari
      #此属性控制池中连接的最长生命周期，值0表示无限生命周期，默认1800000即30分钟
      max-lifetime: 1800000
      # 数据库连接超时时间,默认30秒，即30000
      connection-timeout: 30000
      # 连接测试sql 这个地方需要根据数据库方言差异而配置 例如 oracle 就应该写成  select 1 from dual
      connection-test-query: SELECT 1

# mybatis 相关配置
mybatis:
  configuration:
    # 是否打印sql语句 调试的时候可以开启
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

3.4 新建查询接口

上面Spring+Mybatis我们使用了XML的方式来写SQL，为了体现Mybatis支持多种方式，这里使用注解的方式来写SQL。

@Mapper
public interface PopulationDao {

    @Select("SELECT * from us_population")
    List<USPopulation> queryAll();

    @Insert("UPSERT INTO us_population VALUES( #{state}, #{city}, #{population} )")
    void save(USPopulation USPopulation);

    @Select("SELECT * FROM us_population WHERE state=#{state} AND city = #{city}")
    USPopulation queryByStateAndCity(String state, String city);


    @Delete("DELETE FROM us_population WHERE state=#{state} AND city = #{city}")
    void deleteByStateAndCity(String state, String city);
}

3.5 单元测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class PopulationTest {

    @Autowired
    private PopulationDao populationDao;

    @Test
    public void queryAll() {
        List<USPopulation> USPopulationList = populationDao.queryAll();
        if (USPopulationList != null) {
            for (USPopulation USPopulation : USPopulationList) {
                System.out.println(USPopulation.getCity() + " " + USPopulation.getPopulation());
            }
        }
    }

    @Test
    public void save() {
        populationDao.save(new USPopulation("TX", "Dallas", 66666));
        USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
        System.out.println(usPopulation);
    }

    @Test
    public void update() {
        populationDao.save(new USPopulation("TX", "Dallas", 99999));
        USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
        System.out.println(usPopulation);
    }


    @Test
    public void delete() {
        populationDao.deleteByStateAndCity("TX", "Dallas");
        USPopulation usPopulation = populationDao.queryByStateAndCity("TX", "Dallas");
        System.out.println(usPopulation);
    }

}

附：建表语句

上面单元测试涉及到的测试表的建表语句如下：

CREATE TABLE IF NOT EXISTS us_population (
      state CHAR(2) NOT NULL,
      city VARCHAR NOT NULL,
      population BIGINT
      CONSTRAINT my_pk PRIMARY KEY (state, city));
      
-- 测试数据
UPSERT INTO us_population VALUES('NY','New York',8143197);
UPSERT INTO us_population VALUES('CA','Los Angeles',3844829);
UPSERT INTO us_population VALUES('IL','Chicago',2842518);
UPSERT INTO us_population VALUES('TX','Houston',2016582);
UPSERT INTO us_population VALUES('PA','Philadelphia',1463281);
UPSERT INTO us_population VALUES('AZ','Phoenix',1461575);
UPSERT INTO us_population VALUES('TX','San Antonio',1256509);
UPSERT INTO us_population VALUES('CA','San Diego',1255540);
UPSERT INTO us_population VALUES('CA','San Jose',912332);
