spring boot sharding jdbc demo介绍

MySQL水平分库使用sharding-jdbc

• MySQL 5.7
• MyBatis
• Spring Boot
• jdk 11

How to start

• 准备两个库shard_00与shard_01
• 建表

CREATE TABLE test_user (
               id bigint primary key NOT NULL,
               username VARCHAR(225) DEFAULT NULL,
               password VARCHAR(225) DEFAULT NULL
);

• 启动，调用UserController API进行试验

测试join

1. shard-00执行

CREATE TABLE test_user_status (
                      id bigint primary key NOT NULL,
                      user_id bigint NOT NULL,
                      status varchar(100) NOT NULL
);

INSERT INTO `test_user` (`id`, `username`, `password`)
VALUES
	(0, 'hello', 'x');

INSERT INTO `test_user_status` (`id`, `user_id`, `status`)
VALUES
    (0, 1, '0');

2. shard-01执行

CREATE TABLE test_user_status (
                      id bigint primary key NOT NULL,
                      user_id bigint NOT NULL,
                      status varchar(100) NOT NULL
);

INSERT INTO `test_user` (`id`, `username`, `password`)
VALUES
	(1, 'hello', 'x');

INSERT INTO `test_user_status` (`id`, `user_id`, `status`)
VALUES
    (0, 0, '0');

3. 验证结果curl localhost:8090/join返回空，结论：sharding-jdbc不支持跨库join
