Eclipse에서 bolt 프로토콜을 사용하여 작동하도록 java 및 neo4j를 실행하는 방법

Question

Eclipse에서 maven 종속성을 사용하고 볼트 프로토콜을 사용하여 neo4j 및 java에 연결하려고합니다. MacOS에서 응용 프로그램을 실행 중입니다. Eclipse 3 및 Java 버전 8과 jre 1.8을 사용하고 있습니다. 이것은 내 pom.xml 파일입니다 **

이, 나는이 모든 오류를 얻고 응용 프로그램을 실행 한 후 된 .java 파일

void createDatabase() 
    { 
     GraphDatabaseService dfs = new GraphDatabaseFactory().newEmbeddedDatabase(dbPath); 
     System.out.println("Database created!!"); 
     Config noSSL = Config.build().withEncryptionLevel(Config.EncryptionLevel.NONE).toConfig(); 

     try(Driver dri = GraphDatabase.driver("bolt://localhost:7687", AuthTokens.basic("neo4j", "hello"), noSSL)) 
     { 
      System.out.println("Database connected"); 

      Session session = dri.session(); 
      session.run("CREATE(a:Persona{name:{name}, title:{title}})", parameters("name","Aruna","title","Bhakt")); 
      System.out.println("\n\t1.CREATED"); 

      StatementResult result =session.run("MATCH(a:Persona) WHERE a.name = {name}" + 
                "RETURN a.name AS name, a.title AS title", 
                parameters("name","Aruna")); 
      System.out.println("\n\t2.Match"); 

      while(result.hasNext()) 
      { 
       Record record = result.next(); 
       System.out.println(record.get("title").asString() + " " + record.get("name").asString()); 

      } 
      System.out.println("\n\t3.Found Record"); 

      session.close(); 
      dri.close(); 
     } 
    }

내 모든 오류를 파악하는 데 도움이됩니다.
