Try X DevAPI of MySQL 8 with Spring WebFlux

Perhaps it's semi-reactive. :)

Install MySQL 8.0

first of all

Create Schema

CREATE SCHEMA `app` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Create Table

create table people
(
	id int auto_increment
		primary key,
	name char(254) null
);

Create User

CREATE USER 'app'@'%' IDENTIFIED BY 'app';
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, FILE, REFERENCES, INDEX,
    ALTER, SHOW DATABASES, SUPER, LOCK TABLES, CREATE VIEW, SHOW VIEW 
    on app.* TO 'app'@'%';
GRANT RELOAD on *.* TO 'app'@'%';
FLUSH PRIVILEGES;

Spring Boot and WebFlux

Define Beans of MySQL

  @Bean
  public Session mySession() {
    return new SessionFactory().getSession("mysqlx://localhost:33060/app?user=app&password=app");
  }

  @Bean
  public Schema mySchema() {
    return mySession().getSchema("app");
  }

  @Bean
  public Table people() {
    return mySchema().getTable("people");
  }

PeopleService and PeopleController.
