八：MyBatis-Plus中处理多数据源

1.创建数据库及表

创建数据库mybatis_plus_1和表product

CREATE DATABASE `mybatis_plus_1` /*!40100 DEFAULT CHARACTER 
SET utf8mb4 */;
USE `mybatis_plus_1`;
CREATE TABLE product (
	id BIGINT ( 20 ) NOT NULL COMMENT '主键ID',
	NAME VARCHAR ( 30 ) NULL DEFAULT NULL COMMENT '商品名称',
	price INT ( 11 ) DEFAULT 0 COMMENT '价格',
	version INT ( 11 ) DEFAULT 0 COMMENT '乐观锁版本号',
PRIMARY KEY ( id ) 
);

添加测试数据 

INSERT INTO product (id, NAME, price) VALUES (1, '外星人笔记本', 100);

删除mybatis_plus库product表 

use mybatis_plus;
DROP TABLE IF EXISTS product;

2.引入依赖

<dependency>
    <groupId>com.baomidougroupId>
    <artifactId>dynamic-datasource-spring-
