mybatis mysql upsert_SpringBoot2.3.4+Mybatis+Phoenix操作HBase2.0.6

SpringBoot2.3.4+Mybatis+Phoenix操作HBase2.0.6

1、環境說明

使用單機版安裝的hbase，版本為2.0.6，phoenix-core的版本使用5.0.0-HBase-2.0需與hbase版本比對，使用mybatis直接操作hbase，大部分文法與操作mysql相同，有小部分差異，如insert or update在此需改為upsert表示插入或更新，同時不支援批量插入文法insert into table values(),();

2、配置編寫應用代碼

建立一個使用者表，可以在phoenix用戶端直接操作

create table if not exists ioe_user (

id bigint not null primary key,

nick_name varchar(50),

name varchar(20),

phone varchar(20),

address varchar(100),

gender integer,

birthday date,

registry_time date,

update_time date

);

3、測試運作

運作測試用例，可以看到mybatis對應的sql語句

: ==> Preparing: delete from ioe_user where id=?

: ==> Parameters: 1(Long)

: <== Updates: 1

: ==> Preparing: upsert into ioe_user(id,nick_name,name,phone,address,gender,birthday,registry_time,update_time) values(?,?,?,?,?,?,?,?,?)

: ==> Parameters: 1(Long), 揚帆起航(String), 邝小(String), 13800000000(String), 北京市東城區(String), 1(Integer), 2020-01-25 22:47:47.652(Timestamp), 2020-01-25 22:47:47.652(Timestamp), 2020-01-25 22:47:47.652(Timestamp)

: <== Updates: 1

: ==> Preparing: upsert into ioe_user(id,nick_name) values(?,?)

: ==> Parameters: 1(Long), 揚帆啟航(String)

: <== Updates: 1

: ==> Preparing: select count(*) from ioe_user

: ==> Parameters:

: <== Total: 1

: 2

: ==> Preparing: select gender,count(*) count from ioe_user group by gender

: ==> Parameters:

: <== Total: 2

: {"count":1,"gender":1}

: {"count":1,"gender":2}

4、安裝使用DBeaver操作HBase

1)、下載下傳DBeaver安裝包dbeaver-ce-7.1.3-win32.win32.x86_64.zip，解壓後進入目錄，在配置檔案dbeaver.ini中增加以下配置指定jdk

-vm

C:\Program Files\jdk1.8.0_66\bin

2)、運作dbeaver.exe，選擇建立新連接配接，選中“Hadoop/BigData”欄的“Apache Phoenix”點選下一步，編輯驅動設定中添加驅動檔案phoenix-5.0.0-HBase-2.0-client.jar，點選“找到類”即可搜尋到對應的驅動類，如圖所示；
