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 Download

完整包下载 lib.0.0.3.zip

安装方式Install for Maven

来自我的私有maven库，加入以下依赖。

<dependency>
		<groupId>org.chenmin.open</groupId>
		<artifactId>objector-ots</artifactId>
		<version>0.0.3</version>
</dependency>
<repositories>
	<repository>

		<name>Team dpm Repository</name>
		<url>http://vpn.dpm.im:8081/nexus/content/repositories/releases/</url>
	</repository>
</repositories>

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

详细源码 点此进入

@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 ......

}

with Guice Example @Inject

详细源码 点此进入

public class ServiceModule extends AbstractModule {

	@Override
	protected void configure() {
		bind(ITableStoreService.class).to(TableStoreService.class);
		bind(IStore.class).to(Store.class);
		bind(Objector.class).to(OtsObjector.class);
	}

}

CRUD for junit test

详细源码 点此进入

public class TestUserService {

	private static Injector injector;
	private static IStore store;

	/**
	 * @throws java.lang.Exception
	 */
	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		//初始化Guice容器
		injector = Guice.createInjector(new ServiceModule());
		store = injector.getInstance(IStore.class);
		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);
		UserObject u = new UserObject();
		u.setOpenid(openid);
		u.setPasswd(passwd2);
		assertTrue(store.update(u));
		t = new UserObject();
		t.setOpenid(openid);
		assertTrue(store.get(t));
		assertEquals(t.getPasswd(), passwd2);
		t = new UserObject();
		t.setOpenid(openid);
		assertTrue(store.del(t));
		assertEquals(t.getPasswd(),null);
	}
