orientDB使用

 OrientDB的java接口文档：

http://www.orientechnologies.com/docs/1.7.8/orientdb.wiki/Java-API.html

 

 

java API：

 

1. 启动orientDB：

sh server.sh

 

2. 登录

http://localhost:2480/

账号： root

密码： CD081B7B8B229411A9AD414AE31547E5E4A087905FBD0302FC5736D0A1751239

  

 

3. 添加maven依赖：

<!-- *** orientdb *** -->
		<dependency>
			<groupId>com.orientechnologies</groupId>
			<artifactId>orient-commons</artifactId>
			<version>1.6</version>
		</dependency>
		<dependency>

4. 使用document API插入数据：

import com.orientechnologies.orient.core.db.document.ODatabaseDocumentTx;
import com.orientechnologies.orient.core.record.impl.ODocument;

/**

 */
public class orientdb_api_document01 {

	public static void main(String[] args) {

		/**
		 *  Document API
		 * 
		 *  ODatabaseDocumentTx是非线程安全的，所以在多线程使用的时候，需要初始化多个实例instances；
		 */
		String database = "remote:localhost/mengka";
		ODatabaseDocumentTx db = new ODatabaseDocumentTx(database).open(
				"admin", "admin");

		/**
		 * 例1： 插入第二行数据
		 * 
		 * 外键：City－北京
		 */
		ODocument out_bbDocument = new ODocument("City");
		out_bbDocument.field("name", "北京");
		out_bbDocument.field("country", "中国");
		ODocument bbDocument = new ODocument("Person");
		bbDocument.field("name", "蒙卡AAA");
		bbDocument.field("surname", "aaa..");
		bbDocument.field("city", out_bbDocument);
		bbDocument.save();

		/**
		 *  释放资源
		 */
		db.close();
	}
}

 

5. 查看数据：

select * from Person
