SEVERE: Failed to start Neo Server on port [7474]
在这里我试图通过程序启动服务器程序代码是，
graphDb = new GraphDatabaseFactory()
.newEmbeddedDatabaseBuilder(DB_PATH)
.setConfig( config )
.newGraphDatabase();
Configurator configurator = new ServerConfigurator((GraphDatabaseAPI)graphDb);
configurator.configuration().setProperty(Configurator.WEBSERVER_ADDRESS_PROPERTY_KEY, "172.25.218.96");
configurator.configuration().setProperty(Configurator.WEBSERVER_PORT_PROPERTY_KEY, 7474);
WrappingNeoServerBootstrapper bootstrapper = new WrappingNeoServerBootstrapper((GraphDatabaseAPI)graphDb, configurator);
bootstrapper.start();
任何人都可以帮我解决这个问题......
谢谢..
