感谢~ gremlin-client已经请求成功
用java gremlin-core 、gremlin-driver请求报错
remote-objects.yaml配置
`hosts: [192.168.100.222]
port: 8182
serializer: {
className:
org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0,
config: {
serializeResultToString: false
}
}`
java 代码
`
Cluster cluster = Cluster.build(new
File("./conf/remote-objects.yaml")).create();
GraphTraversalSource g =
traversal().withRemote(DriverRemoteConnection.using(cluster,"g"));
System.out.println(g.V().count().toList());
`
`Exception in thread "main" java.util.concurrent.CompletionException:
