简介：

Neo4j是一个网络——面向图网络的数据库——也就是说，它是一个嵌入式的、基于磁盘的、具备完全的事务特性的Java持久化引擎，但是它将结构化数据存储在图网络上而不是表中。图网络（从数学角度叫做图）是一个灵活的数据结构，可以应用更加敏捷和快速的开发模式。

嵌入式使用代码如下：

RelationshipType：

enum UserRelationship implements RelationshipType {	FELLOW, BELONG}

调用：

public static void main(String[] args) {	String DB_PATH = "G:/neo4j/db/data1/";	GraphDatabaseFactory factory = new GraphDatabaseFactory();	GraphDatabaseService gds = factory.newEmbeddedDatabase(DB_PATH);	GlobalGraphOperations ggo = GlobalGraphOperations.at(gds);	Transaction tx = gds.beginTx();	try {		Node fromNode = gds.createNode();		fromNode.setProperty("table", "person");		fromNode.setProperty("name", "马云");		Node toNode = gds.createNode();		toNode.setProperty("table", "person");		toNode.setProperty("name", "李彦宏");		Relationship relationship = fromNode.createRelationshipTo(toNode,			UserRelationship.FELLOW);		List
    
      eventList = new ArrayList
     
      ();		eventList.add("2013福布斯中国富豪榜:李彦宏第三、马化腾第五、马云第八 ");		eventList.add("李彦宏推轻应用马云入股浏览器 移动入口争夺暗战升级 ");		relationship.setProperty("event", JSON.toJSONString(eventList));		Node companyNode = gds.createNode();		companyNode.setProperty("table", "company");		companyNode.setProperty("name", "阿里巴巴");		Relationship belongRelationship = fromNode.createRelationshipTo(companyNode,			UserRelationship.BELONG);		belongRelationship.setProperty("event", "马云如何掌控阿里巴巴? ");		tx.success();	} catch (Throwable e) {		e.printStackTrace();		tx.failure();	} finally {		tx.finish();	}	Iterator
      
        iterator = ggo.getAllNodes().iterator();	while (iterator.hasNext()) {		Node node = iterator.next();		Iterator
       
         keysIterator = node.getPropertyKeys().iterator();		while (keysIterator.hasNext()) {			String key = keysIterator.next();			System.out.println(key + "->" + node.getProperty(key));		}		Iterator
        
          relationshipsIterator = node.getRelationships().iterator();		while (relationshipsIterator.hasNext()) {			Relationship relationships = relationshipsIterator.next();			System.out.println("关系：" + relationships.getType());		}	}	gds.shutdown();}
