Java Neo4j数据未显示在web控制台中

我正试图编写一个程序，将数据输入Neo4j数据库。该计划似乎运行良好-我说，因为它运行没有问题和

System.out.println(node.getProperty("Name"));

第行返回我创建的每个节点的值。然而，当我转到web控制台时，在数据库中看不到任何这些节点。我肯定我正在把它写到正确的目录。执行

ls-l

显示每次运行程序时db都会被修改：

然而当我进去的时候

START a=node（*）
返回a

我没有节点。如果我在这个数据库上运行EmbeddedNeo4j.java示例，那么这些节点将显示在数据库中，而不是这些节点。控制台配置设置显示相同的目录

我是否遗漏了什么，或者Neo4J中是否存在错误

下面是我使用的课程，仅供参考。Main调用tester，它打开一个流。流获得数据库的句柄，并在将规则应用于输入（未显示）后，使用NeoProcessor创建条目。属性被毫无问题地打印到控制台，这让我相信它们已经写入数据库，但我从未在web控制台中看到它们

我的主要意见是：

public class NeoTest {


    public static void main( final String[] args )
    {


        //Our tester to test the database
        Tester myTest = new Tester("Stream");

        try{
            myTest.fileTester("/Users/me/data/test");
            myTest.end();
        }
        catch (IOException ex)
        {
            System.out.println("Cannot open file fool");
        }

    }


}

我的测试人员：

public class Tester {

    private Streamer myStream;
    private String inputType;

    public Tester(String inputType)
    {
        this.inputType = inputType;
        if(inputType.toLowerCase().contains("Stream".toLowerCase()))
        {
            System.out.println("Using Stream");
            // instantiate streamer
            myStream = new Streamer();
            //get DB going
            myStream.openStream("calllog");
        }
    }

    public void fileTester(String fileName) throws IOException
    {
        System.out.println("hi");
        BufferedReader in = new BufferedReader(new FileReader(fileName));

        while(in.ready())
        {
            String s = in.readLine();
            myStream.streamInput(s);
        }
        in.close();
    }

    public void end()
    {
        if(inputType.toLowerCase().contains("Stream".toLowerCase()))
                myStream.closeStream();
    }

}

我的经纪人是：

public class NeoHandle {

    private static GraphDatabaseService graphDb;
    private String DB_PATH = "/usr/local/Cellar/neo4j/2.0.1/libexec/data/new_graph.db";

    NeoHandle()
    {
        this.graphDb = new GraphDatabaseFactory().newEmbeddedDatabase( DB_PATH );
    }


    public GraphDatabaseService getNeoHandle()
    {
        return graphDb;
    }

    public void createDb()
    {
        // START SNIPPET: startDb
        registerShutdownHook( graphDb );
        // END SNIPPET: startDb
    }

    private static void registerShutdownHook( final GraphDatabaseService graphDb )
    {
        // Registers a shutdown hook for the Neo4j instance so that it
        // shuts down nicely when the VM exits (even if you "Ctrl-C" the
        // running application).
        Runtime.getRuntime().addShutdownHook( new Thread()
        {
            @Override
            public void run()
            {
                graphDb.shutdown();
            }
        } );
    }

    public void shutDown()
    {
        System.out.println();
        System.out.println( "Shutting down database ..." );
        // START SNIPPET: shutdownServer
        graphDb.shutdown();
        // END SNIPPET: shutdownServer
    }
}

我的拖缆是：

public class Streamer {

    private NeoHandle myHandle;

    private String contextType;

    Streamer()
    {

    }


    public void openStream(String contextType)
    {
        myHandle = new NeoHandle();
        myHandle.createDb();
    }

    public void streamInput(String dataLine)
    {
        LinkedList context = new LinkedList();
        /*
         * get database instance
         * write to database
         * check for errors
         * report errors & success
         */
        System.out.println(dataLine);

        //apply rules to data (make ContextRules do this, send type and string of data)
        ContextRules contextRules = new ContextRules();
        context = contextRules.processContextRules("Calls", dataLine);

        //write data (using linked list from contextRules)
        NeoProcessor processor = new NeoProcessor(myHandle);
        processor.processContextData(context);
    }

    public void closeStream()
    {
        /*
         * close database instance
         */
        myHandle.shutDown();
    }

}

我的处理器是：

public class NeoProcessor {

    private NeoHandle handle;

    public NeoProcessor(NeoHandle handle)
    {
        this.handle = handle;
    }

    public void processContextData(LinkedList context)
    {
        for(Object c : context)
        {
            if(c instanceof Entity)
            {
                Node node = addNode((Entity)c);
                ((Entity)c).setNode(node);          
            }

        }
    }

    public Node addNode(Entity myNode)
    {   
        //TODO - wrap in transaction
        GraphDatabaseService graphDb = this.handle.getNeoHandle();

        Node node;


        try ( Transaction tx = graphDb.beginTx() )
        {
            node = graphDb.createNode();
            if(myNode.hasName()) 
                {
                System.out.println("setting name");
                node.setProperty("Name", myNode.getName());
                System.out.println(node.getProperty("Name"));
                }

        }//try transaction  

        return node;
    }
}

我遗漏了NeoProcessor中的
tx.success（）
调用。当我将其包装在一个事务中时，我必须提交该事务。
UGGGG，在这里输入所有这些之后，我发现了问题所在。我漏掉了tx.success（）；在NeoProcessor类方法addNode中的事务结束时调用。我将回答这个问题，因为我认为把这个问题保留在这里比删除它更好，因为它可以（？）作为其他人的一个例子？
