案例
我在 Java 中使用 ResultSet 的 submit 方法(由 org.apache.tinkerpop:gremlin-driver:3.0.1-incubating dependency 提供)来查询 gremlin 服务器。我需要知道如何配置我的客户端以接收 JSON 格式的响应。
我做了什么
我尝试使用 GraphSONMessageSerializerV1d0 和 GraphSONMessageSerializerGremlinV1d0 序列化程序,但响应不是有效的 json。这是我的 gremlin-server.yaml 文件
authentication: {className:
org.apache.tinkerpop.gremlin.server.auth.AllowAllAuthenticator,
config: null}
channelizer:
org.apache.tinkerpop.gremlin.server.channel.WebSocketChannelizer

maxAccumulationBufferComponents: 1024
maxChunkSize: 8192

csvReporter: null
gangliaReporter: null
graphiteReporter: null
jmxReporter: null
slf4jReporter: {enabled: true, interval: 180000, loggerName:

null, trustCertChainFile: null}

如果有人可以帮助我配置客户端以接收 JSON 格式的结果,那就太好了!
