• 編寫application.yml

  spring:
    datasource:
      type: com.alibaba.druid.pool.DruidDataSource
      driver-class-name: org.apache.phoenix.jdbc.PhoenixDriver
      url: jdbc:phoenix:192.168.19.148:2181
      username: root
      password: root
  
  mybatis:
    mapper-locations: classpath:com/jun/mapper/*.xml
    type-aliases-package: com.junjia.entity
  
  

• 編寫Application啓動類

  package com.junjia;
  
  import org.mybatis.spring.annotation.MapperScan;
  import org.springframework.boot.SpringApplication;
  import org.springframework.boot.autoconfigure.SpringBootApplication;
  @SpringBootApplication
  @MapperScan("com.junjia.dao")
  public class Application {
      public static void main(String[] args) {
          SpringApplication.run(Application.class,args);
      }
  }
  
  

• 創建實體

  package com.junjia.entity;
  
  import lombok.Data;
  
  import java.util.Date;
  @Data
  public class Order {
  
  
    private Integer id;
  
    private String orderCode;
  
    private Float totalAmount;
  
    private Date createTime;
  
    private Integer userId;
  }
  
  

• 編寫DAO接口

  package com.junjia.dao;
  
  import com.junjia.entity.Order;
  
  import java.util.List;
  public interface OrderDao {
      /**
       * 查詢所有數據
       * @return
       */
      List<Order> queryAll();
  }
  
  

• 編寫Mapper文件

  <?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.junjia.dao.OrderDao">
    <resultMap id="BaseResultMap" type="com.junjia.entity.Order">
         <result column="id" jdbcType="INTEGER" property="id"/>
        <result column="order_code" jdbcType="VARCHAR" property="orderCode"/>
        <result column="total_amount" jdbcType="DECIMAL" property="totalAmount"/>
        <result column="create_time" jdbcType="TIMESTAMP" property="createTime"/>
        <result column="user_id" jdbcType="INTEGER" property="userId"/>
    </resultMap>
  <sql id="BaseSql">
        id,order_code,total_amount,create_time,user_id
  </sql>
   <select id="queryAll" resultMap="BaseResultMap">
       select <include refid="BaseSql"/> from car_order
   </select>
  
  </mapper>
  

• 創建Serivice

  package com.junjia.service;
  
  import com.junjia.entity.Order;
  
  import java.util.List;
  
  public interface OrderService {
      /**
       * 查詢所有數據
       * @return
       */
      List<Order> queryAll();
  }
  
  

• 創建實現類

  package com.junjia.service;
  
  import com.junjia.dao.OrderDao;
  import com.junjia.entity.Order;
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.stereotype.Service;
  
  import java.util.List;
  
  @Service
  public class OrderServiceImpl implements OrderService{
      @Autowired
      private OrderDao orderDao;
  
      @Override
      public List<Order> queryAll() {
          List<Order> orders = orderDao.queryAll();
          return orders;
      }
  }
  
  

• 編寫測試類

  package com.junjia;
  
  import com.junjia.entity.Order;
  import com.junjia.service.OrderService;
  import org.junit.Test;
  import org.junit.runner.RunWith;
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.boot.test.context.SpringBootTest;
  import org.springframework.test.context.junit4.SpringRunner;
  
  import java.util.List;
  @RunWith(SpringRunner.class)
  @SpringBootTest(classes = Application.class)
  public class TestPhoenix {
  
      @Autowired
      private OrderService orderService;
  
      @Test
      public void queryAll(){
          List<Order> orders = orderService.queryAll();
          for (Order order : orders) {
              System.out.println(order);
          }
      }
  
  }
