Question

我已经开始使用我的neo4j基础了...... 我的neo4j要求更新的版本，而我的是最新版本，我是否需要更正我的代码中的任何内容（此处如下）或安装或更新的任何内容。

**在代码中newEmbeddedDatabase已被弃用，我不知道如何纠正..

**当我启动neo4j服务器时，它显示一条Alert消息＆＃34;无法使用较旧的数据存储版本启动Neo4j。要启用自动升级，请设置配置参数＆＃34; allow_store_upgrade = true＆＃34; ＆＃34;

**我启用了allow_store_upgrade = true并使用了neo4j 2.3.2 请帮我提前致谢

package neo4j;
public class neo4j_demo {
public static void main(String[] args) 
  {

   GraphDatabaseFactory dbFactory =new GraphDatabaseFactory();

        GraphDatabaseService db= dbFactory.newEmbeddedDatabase("C:/TPNeo4jDB");
        try (Transaction tx = db.beginTx()) {

            Node javaNode = db.createNode(Tutorials.JAVA);
            javaNode.setProperty("TutorialID", "JAVA001");
            javaNode.setProperty("Title", "Learn Java");
            javaNode.setProperty("NoOfChapters", "25");
            javaNode.setProperty("Status", "Completed");                

            Node scalaNode = db.createNode(Tutorials.SCALA);
            scalaNode.setProperty("TutorialID", "SCALA001");
            scalaNode.setProperty("Title", "Learn Scala");
            scalaNode.setProperty("NoOfChapters", "20");
            scalaNode.setProperty("Status", "Completed");

            Relationship relationship = javaNode.createRelationshipTo
            (scalaNode,TutorialRelationships.JVM_LANGIAGES);
            relationship.setProperty("Id","1234");
            relationship.setProperty("OOPS","YES");
            relationship.setProperty("FP","YES");

            tx.success();
        }
           System.out.println("Done successfully");
    }

}

你检查过你的maven依赖吗？您可能希望用此替换您的maven条目。

<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>2.X.X</version>
</dependency>
