1.简介

官网: https://www.kingbase.com.cn/

2. 安装

TODO 补充 docker安装

3. 基础使用

3.1 客户端连接

使用idea自带database查询

3.2 表数据测试

3.2.1 建表

创建从10000开启自增id的用户表，username增加唯一索引

CREATE TABLE account(
    id          BIGINT      NOT NULL GENERATED BY DEFAULT AS IDENTITY (START WITH 10000),
    username    VARCHAR(32) NOT NULL,
    password    VARCHAR(32)  DEFAULT NULL,
    name        VARCHAR(20)  DEFAULT NULL,
    sex         CHAR(1)      DEFAULT NULL,
    phone       VARCHAR(100) DEFAULT NULL,
    email       VARCHAR(100) DEFAULT NULL,
    create_time TIMESTAMP    DEFAULT NULL,
    update_time TIMESTAMP    DEFAULT NULL,
    extend_json JSON         DEFAULT NULL,
    PRIMARY KEY (id),
    UNIQUE (username)
);

3.2.2 数据写入测试

-- 插入第一行数据
INSERT INTO account (username, password, name, sex, phone, email, create_time, update_time, extend_json)
VALUES ('user1', 'pass1', 'John Doe', 'M', '123456789', 'user1@example.com', CURRENT_TIMESTAMP, CURRENT_TIMESTAMP, '{"key": "value1"}');

-- 插入第二行数据
INSERT INTO account (username, password, name, sex, phone, email, create_time, update_time, extend_json)
VALUES ('user2', 'pass2', 'Jane Doe', 'F', '987654321', 'user2@example.com', CURRENT_TIMESTAMP, CURRENT_TIMESTAMP, '{"key": "value2"}');

-- 插入第三行数据
INSERT INTO account (username, password, name, sex, phone, email, create_time, update_time, extend_json)
VALUES ('user3', 'pass3', 'Bob Smith', 'M', '555555555', 'user3@example.com', CURRENT_TIMESTAMP, CURRENT_TIMESTAMP, '{"key": "value3"}');


INSERT INTO account (username, password, name, sex, phone, email, create_time, update_time, extend_json)
VALUES
('user4', 'pass1', 'John Doe', 'M', '123456789', 'user1@example.com', '2022-01-01 10:00:00', '2022-01-01 10:00:00', '{"key": "value1"}'),
('user5', 'pass2', 'Jane Doe', 'F', '987654321', 'user2@example.com', '2022-01-01 11:00:00', '2022-01-01 11:00:00', '{"key": "value2"}'),
('user6', 'pass3', 'Bob Smith', 'M', '555555555', 'user3@example.com', '2022-01-01 12:00:00', '2022-01-01 12:00:00', '{"key": "value3"}');

3.2.2 查询测试

json查询测试

json指定key查询

SELECT * FROM account WHERE extend_json ->> 'address' LIKE '%吕街28号%';

SELECT * FROM account WHERE extend_json ->> 'address' = 'Suite 231 吕街28号, 包头, 藏 351579';

4.springboot实战

使用依赖版本:

<spring-boot.version>2.3.2.RELEASE</spring-boot.version>

4.1 maven依赖

        <!--人大金仓数据库驱动-->
        <dependency>
            <groupId>cn.com.kingbase</groupId>
            <artifactId>kingbase8</artifactId>
            <version>8.6.0</version>
        </dependency>

4.2 连接配置

application.yml补充kingbase连接

spring:
  datasource:
    driver-class-name: dm.jdbc.driver.DmDriver
    url: jdbc:kingbase8://192.168.8.33:54321/testdb
    username: system
    password: kingbase

4.3 mybatis-plus测试

TODO

4.4 liquibase整合

liquibase基本不支持国产数据库，但是kingbase借助切换pg的驱动可以间接实现

(1). 使用pg方式替换kingbase驱动上面

        <dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
            <scope>runtime</scope>
        </dependency>

(2). 修改jdbc url配置

spring:
  datasource:
    #driver-class-name: dm.jdbc.driver.DmDriver
    #url: jdbc:kingbase8://192.168.8.33:54321/testdb
    driver-class-name: org.postgresql.Driver
    url: jdbc:postgresql://192.168.8.33:54321/testdb
    username: system
    password: kingbase
