Objector
Objector 是一个简单的对象创建器。
主要支持普通的Pojo对象通过@annotation方式进行字节码增强，将对象直接持久化的微型框架。
目前采用阿里云的表格存储实现，详情见 https://www.aliyun.com/product/ots 待此版本稳定后，将提供其他实现方式如MongoDB
安装方式Install for Maven
来自maven中心库，加入以下依赖。
<dependency>
<groupId>org.chenmin.open</groupId>
<artifactId>objector-ots</artifactId>
<version>0.2.4.1</version>
</dependency>
使用方式Useage
阿里云配置Config for Aliyun.com OpenTableStore
请再classpath中加入配置文件根目录objector.properties
objector.properties in classpath

Pojo with Annotation
@Entity//表示此对象为持久化实体
public class UserObject implements Serializable {
@Key(index = true)//主键，和索引
private String openid;
@Column//列名称
private String passwd;
//some getter and setter ......
}
CRUD for junit test
public class TestUserService {
private static IStore store;
/**

*/
@BeforeClass
public static void setUpBeforeClass() throws Exception {
store =StoreFactory.create();
UserObject u = new UserObject();
if (!store.exsitTable(u)) {
store.createTable(u);
}
}
@Test
public void test() {
UserObject userObject = new UserObject();
String openid = "chenmintest";
String passwd = "12345678";
String passwd2 = "12";
userObject.setOpenid(openid);
userObject.setPasswd(passwd);
assertTrue(store.save(userObject));
UserObject t = new UserObject();
t.setOpenid(openid);
assertTrue(store.get(t));
assertEquals(t.getPasswd(), passwd);

u.setPasswd(passwd2);
assertTrue(store.update(u));
t = new UserObject();
t.setOpenid(openid);

assertEquals(t.getPasswd(), passwd2);
t = new UserObject();
t.setOpenid(openid);
assertTrue(store.del(t));
assertEquals(t.getPasswd(),null);
}
