mybatis-reactive

reactive,non-blocking io mybatis based on r2dbc with kotlin coroutines support

响应式、非阻塞 mybatis 实现, 支持kotlin协程

mybatis-reactive是一个响应式版mybatis持久层框架，可以通过简单的 XML 或注解来配置和映射原始类型、接口和 Java POJO为数据库中的记录。

支持以下特性

Reactive

mapper 返回值支持 Mono、Flux，以非阻塞方式与数据库IO请求
协程

支持kotlin协程，映射函数可声明为suspend，以同步方式处理异步
插件机制

支持插件机制，可实现类似分页插件等

与mybatis对比接口变化

mybatis-reactive	mybatis (jdbc)
ReactiveSqlSession	SqlSession
ReactiveSqlSessionFactory	SqlSessionFactory
ReactiveExecutor	Executor
ReactiveStatementHandler	StatementHandler
ReactiveParameterHandler	ParameterHandler
ReactiveResultSetHandler	ResultSetHandler

快速开始

下载源码编译

    git clone https://github.com/zimatars/mybatis-reactive.git
    cd mybatis-reactive/
    mvn -Dmaven.test.skip=true clean install

选择驱动

可参考该网址 https://r2dbc.io/drivers 选择对应r2dbc驱动

如：mysql

    <dependency>
        <groupId>dev.miku</groupId>
        <artifactId>r2dbc-mysql</artifactId>
        <version>0.8.2.RELEASE</version>
    </dependency>

mybatis-reactive

    <dependency>
        <groupId>com.waterdrop</groupId>
        <artifactId>mybatis-reactive</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

mybatis-reactive-boot-starer

与spring boot集成

1.starter

    <dependency>
        <groupId>com.waterdrop</groupId>
        <artifactId>mybatis-reactive-boot-starter</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

2.数据源配置

spring:
  r2dbc:
    url: r2dbc:mysql://ip:port/databaseName
    username: name
    password: 123***

3.mapper声明

@Mapper
public interface UserMapper {
    Mono<User> getById(Long id);

    Flux<User> selectList();
}

kotlin协程支持，mapper支持suspend函数

@Mapper
interface UserKtMapper {
    suspend fun getById(id: Long): User?

    suspend fun selectList(): List<User>
}

mybatis-reactive-spring

与spring集成

    <dependency>
        <groupId>com.waterdrop</groupId>
        <artifactId>mybatis-reactive-spring</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

mybatis-reactive-page-plugin

分页插件

    <dependency>
        <groupId>com.waterdrop</groupId>
        <artifactId>mybatis-reactive-page-plugin</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

配置分页插件

  @Bean
  public PaginationInterceptor paginationInterceptor(){
    return new PaginationInterceptor();
  }

@Mapper
public interface UserMapper {
    Flux<User> selectList(Pagination pagination);
}
