Neo4j的螺栓通过的Neo4j-Java的应用程序连接卡住

Question

我连接的Neo4j社区-3.1.1非本地服务器这样的：

Driver driver = GraphDatabase.driver("bolt://10.209.20.211:7687", 
      AuthTokens.basic("username", "xxxx")); 
    System.out.println("neo4j driver created.."); 
    Session session = driver.session(); 
    System.out.println("session opened.."); 

但它永远无法达到“的System.out.println（ “会议开幕..”）;“显然，它在“driver.session（）;”时卡住了，

我敢肯定，网络是工作，我已经通过“telnet 10.209.20.211 7687”测试。

而且neo4j.conf文件是这样的：

#***************************************************************** 
    # Network connector configuration 
    #***************************************************************** 

    # With default configuration Neo4j only accepts local connections. 
    # To accept non-local connections, uncomment this line: 
    dbms.connectors.default_listen_address=0.0.0.0 

    # You can also choose a specific network interface, and configure a non-default 
    # port for each connector, by setting their individual listen_address. 

    # The address at which this server can be reached by its clients. This may be the server's IP address or DNS name, or 
    # it may be the address of a reverse proxy which sits in front of the server. This setting may be overridden for 
    # individual connectors below. 
    #dbms.connectors.default_advertised_address=localhost 

    # You can also choose a specific advertised hostname or IP address, and 
    # configure an advertised port for each connector, by setting their 
    # individual advertised_address. 

    # Bolt connector 
    dbms.connector.bolt.enabled=true 
    #dbms.connector.bolt.tls_level=OPTIONAL 
    #dbms.connector.bolt.listen_address=:7687 

    # HTTP Connector. There must be exactly one HTTP connector. 
    dbms.connector.http.enabled=true 
    #dbms.connector.http.listen_address=:7474 

现在，有什么问题呢？

我用下面的代码解决此问题：

Config cfg = Config.build().withEncryptionLevel(Config.EncryptionLevel.NONE).toConfig(); 
Driver driver = GraphDatabase.driver("bolt://10.209.20.211:7687", 
     AuthTokens.basic("username", "xxxx"), cfg); 
System.out.println("neo4j driver created.."); 
Session session = driver.session(); 
System.out.println("session opened..");
