sharding-jdbc是由当当捐入给apache的一款分布式数据库中间件，支持垂直分库、垂直分表、水平分库、水平分表、读写分离、分布式事务和高可用等相关功能。

1、ruoyi-framework\pom.xml模块添加sharding-jdbc整合依赖

<!-- sharding-jdbc分库分表 -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-jdbc-core</artifactId>
    <version>4.1.1</version>
</dependency>

2、创建两个测试数据库

create database `ry-order1`;
create database `ry-order2`;

3、创建两个测试订单表

-- ----------------------------
-- 订单信息表sys_order_0
-- ----------------------------
drop table if exists sys_order_0;
create table sys_order_0
(
  order_id      bigint(20)      not null                   comment '订单ID',
  user_id       bigint(64)      not null                   comment '用户编号',
  status        char(1)         not null                   comment '状态（0交易成功 1交易失败）',
  order_no      varchar(64)     default null               comment '订单流水',
  primary key (order_id)
) engine=innodb comment = '订单信息表';

-- ----------------------------
-- 订单信息表sys_order_1
-- ----------------------------
drop table if exists sys_order_1;
create table sys_order_1
(
  order_id      bigint(20)      not null                   comment '订单ID',
  user_id       bigint(64)      not null                   comment '用户编号',
  status        char(1)         not null                   comment '状态（0交易成功 1交易失败）',
  order_no      varchar(64)     default null               comment '订单流水',
  primary key (order_id)
) engine=innodb comment = '订单信息表';

4、配置文件application-druid.yml添加测试数据源

# 数据源配置
spring:
    datasource:
        type: com.alibaba.druid.pool.DruidDataSource
        driverClassName: com.mysql.cj.jdbc.Driver
        druid:
            # 主库数据源
            master:
                url: jdbc:mysql://localhost:3306/ry?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
                username: root
                password: password
            # 订单库1
            order1:
                enabled: true
                url: jdbc:mysql://localhost:3306/ry-order1?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
                username: root
                password: password
            # 订单库2
            order2:
                enabled: true
                url: jdbc:mysql://localhost:3306/ry-order2?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
                username: root
                password: password

5、下载插件相关包和代码实现覆盖到工程中

若依插件集成包sharding-jdbc.zip
https://www.alipan.com/s/H1h8xHxKaki

6、测试验证

访问：http://localhost/order/add/1

入库到ry-order2

访问：http://localhost/order/add/2

入库到ry-order1

同时根据订单号order_id % 2入库到sys_order_0或者sys_order_1
