HBase入门 springboot整合mybatis-plus结合phoenix （十三）

一、pom文件

要注意phoenix-core和phoenix-hbase-compat的版本要对应

</project>

2、application.yaml

server:
  port: 8081
##phoenix连接
spring:
  datasource:
    #Phoenix,zookeeper 地址
    url: jdbc:phoenix:hadoop100,hadoop101,hadoop102:2181
    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:
      minimum-idle: 100
      maximum-pool-size: 300
      # 允许最长空闲时间
      idle-timeout: 30000
      # 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-plus:
  mapper-locations: classpath*:mapper/**/*.xml
  type-aliases-package: com.longer.entity
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

3、config

package com.longer.config;

import com.baomidou.mybatisplus.core.injector.AbstractMethod;
import com.baomidou.mybatisplus.core.injector.DefaultSqlInjector;
import com.baomidou.mybatisplus.extension.injector.methods.Upsert;

import java.util.List;

public class UpsertInjector extends DefaultSqlInjector {

    @Override
    public List<AbstractMethod> getMethodList(Class<?> mapperClass) {
        List<AbstractMethod> methodList = super.getMethodList(mapperClass);
        methodList.add(new Upsert());
        return methodList;
    }

}

package com.longer.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MybatisPlusHBasePhoenixConfig {

    @Bean
    public UpsertInjector upsertSqlInjector () {
        return new UpsertInjector();
    }
}

4、dao

package com.longer.dao;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.longer.entity.Student;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface StudentDao extends BaseMapper<Student> {
}

5、entity

package com.longer.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.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("\"bigdata\".\"student\"")
public class Student {
    //标注id
    @TableId(type = IdType.INPUT,value = "ID")
    private String id;
    //注意必须写规范,不加"代表全大写
    @TableField("\"info\".\"name\"")
    private String name;
    @TableField("\"msg\".\"age\"")
    private Integer age;
}

6、crontroller

package com.longer.controller;

import com.longer.dao.StudentDao;
import com.longer.entity.Student;
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.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/student")
public class StudentController {
    @Autowired
    private StudentDao studentDao;


    @GetMapping("/getStudentById")
    public Student getStudentById(@RequestParam("id")String id){
        return studentDao.selectById(id);
    }


}

7、hbase-site.xml

我是直接拷贝phoenix下的

<?xml version="1.0"?>

-->
<configuration>
  <property>
    <name>hbase.regionserver.wal.codec</name>
    <value>org.apache.hadoop.hbase.regionserver.wal.IndexedWALEditCodec</value>
  </property>
  <property>
      <name>phoenix.schema.isNamespaceMappingEnabled</name>
      <value>true</value>
  </property>
  <property>
      <name>phoenix.schema.mapSystemTablesToNamespace</name>
      <value>true</value>
  </property>
</configuration>

application

package com.longer;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Component;

@SpringBootApplication
@MapperScan("com.longer.dao")
public class HbaseExampleApplication {

    public static void main(String[] args) {
        SpringApplication.run(HbaseExampleApplication.class, args);
    }

}

10、测试成功

如果报错

2023-05-14 19:51:35.685 ERROR 14748 --- [nio-8081-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: org/apache/phoenix/compat/hbase/CompatSteppingSplitPolicy] with root cause

java.lang.ClassNotFoundException: org.apache.phoenix.compat.hbase.CompatSteppingSplitPolicy

要看看pom文件有没有导入，还要看看版本号是否对的上

 		<dependency>
            <groupId>org.apache.phoenix</groupId>
            <artifactId>phoenix-hbase-compat-2.4.0</artifactId>
            <version>5.1.2</version>
        </dependency>

phoenix插入更新是用upsert

所以不能用mybatis的update和insert
