## 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~。
