## 简介

Potato ORM 是用Java实现的一个简单的ORM框架，SQL方言目前(未来也)仅支持MySQL，仅供娱乐参考~

## 如何使用？

1.引入Maven 依赖

```xml

    com.github.lihengming

    potato-orm

    1.1

    mysql

    mysql-connector-java

    5.1.38

    ch.qos.logback

    logback-classic

    1.1.7

```

2.在classpath下添加配置文件application.properties

```xml

# JDBC配置，请以你的实际参数进行更改

jdbc.url=jdbc:mysql://localhost:3306/example?useUnicode=true&characterEncoding=utf-8

jdbc.user=root

jdbc.password=123456

# JDBC连接池配置但并不是必须的

# pool.minsize=5

# pool.maxsize=15

```

3.创建Model 并继承Model

```java

public class User extends Model {

    private Long id;

    private String username;

    private Integer age;

    @Column(name = "nick_name")//如果你的表字段如Model的属性名称一致的话需要使用@Column注解

    private String nickName;

    

    //省略getter、setter

}

```

4.使用例子

```java

    @Test

    public void test() {

        User user = new User();

        user.setUsername("potato");

        user.setAge(24);

        user.save();//持久化

        Assert.assertNotNull(user.getId());//持久化之后自动注入自增主键

        Query query = user.createQuery();//获得Query对象

        List userList = query.list();//查询所有用户

        Assert.assertTrue(userList.size() > 0);

        Assert.assertTrue("potato".equals(userList.get(0).getUsername()));

        user.setUsername("potato2");//重新设置username

        user.update();//更新

        User result  = query.findBy("username", "potato2");//根据条件查询

        Assert.assertTrue("potato2".equals(result.getUsername()));

        result.delete();//删除

        Assert.assertTrue(query.list().isEmpty());

    }

```

## 使用建议

本框架仅限于娱乐，因为它可能只是一个简简单单的玩具轮子，并且随时可能会爆胎，所以并不建议你使用它上路~。
