# 项目简介
[mybatis](https://github.com/houbb/mybatis) 是一款简化版的 mybatis 实现。
[![Maven Central](https://maven-badges.herokuapp.com/maven-central/com.github.houbb/mybatis/badge.svg)](http://mvnrepository.com/artifact/com.github.houbb/mybatis)
[![Build Status](https://www.travis-ci.org/houbb/mybatis.svg?branch=master)](https://www.travis-ci.org/houbb/mybatis?branch=master)

[![Open Source Love](https://badges.frapsoft.com/os/v2/open-source.svg?v=103)](https://github.com/houbb/mybatis)## 创作目的
- 学习 mybatis 的原理
- 便于拓展自己的数据库工具
# 快速开始
## 需要
- jdk 1.7+
- maven 3.x+
## maven 引入
```xml
com.github.houbb
mybatis
0.1.0```
## 准备工作
- sql 建表
在 test 数据库执行下面的建表语句。
```sql
-- auto-generated definition
use test;
create table user
(
id int auto_increment
primary key comment '唯一主键',
name varchar(100) not null comment '姓名',
password varchar(100) not null comment '密码',
create_time char(17) comment '创建时间'
) CHARACTER SET utf8 COLLATE utf8_general_ci;-- init
insert into user (name, password) value ('luna', '123456');
```- 配置文件
```xml
```
备注:默认使用的是 mysql 5.7,如果为 8.0+,需要自行引入 jar。
## 运行测试代码
```java
public static void main(String[] args) {
Config config = new XmlConfig("mybatis-config-5-7.xml");SqlSession sqlSession = new DefaultSessionFactory(config).openSession();
UserMapper userMapper = sqlSession.getMapper(UserMapper.class);User user = userMapper.selectById(1L);
System.out.println(user);
}
```- 输出
```
User{id=1, name='ryo', password='123456', createTime=Wed Jul 01 22:03:01 CST 2020}

# 后期 road-map
- [x] 日志组合
- [x] 连接池管理
- [x] TX 管理
~~- [ ] 数据库厂商标识(databaseIdProvider)~~
- [ ] api 方法配置全接口,便于直接配置使用。
- [ ] 添加 MBG
- [ ] 添加 spring 整合实现
- [ ] 添加 spring-boot 整合实现
- [ ] 自增强-类似 mybatis-plus 模块。让组件使用起来更加方便
保持核心功能的简单,保证使用的强大便捷。
