我試圖在使用gremlin/java圖形模式與cosmossDB模擬器時出現問題並陷入困境。當使用gremlin連接到Azure cosmossDB仿真器時的超時連接
模擬器是所有安裝，運行和證書導入到我的Java密鑰庫（我可以連接使用文檔界面，所以我知道這工作）。
模擬器Web控制檯目前正在顯示集合而不是圖形。
我的簡單代碼（Groovy腳本）看起來像這樣
Cluster cluster
Client client
try {
def builder = Cluster.build()
builder.addContactPoint("localhost")
.port(8081)
.protocol ("https")
.keyPassword("C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==")
.enableSsl(true)
cluster = builder.create()
} catch (Exception ex) {
ex.printStackTrace()
}
client = cluster.connect()
String[] gremlinQueries = [
"g.V().drop()",
"g.addV('person').property('id', 'thomas').property('firstName', 'Thomas').property('age', 44)",
"g.addV('person').property('id', 'mary').property('firstName', 'Mary').property('lastName', 'Andersen').property('age', 39)",
"g.addV('person').property('id', 'ben').property('firstName', 'Ben').property('lastName', 'Miller')",
"g.addV('person').property('id', 'robin').property('firstName', 'Robin').property('lastName', 'Wakefield')",
"g.V('thomas').addE('knows').to(g.V('mary'))",
"g.V('thomas').addE('knows').to(g.V('ben'))",
"g.V('ben').addE('knows').to(g.V('robin'))",
"g.V('thomas').property('age', 44)",
"g.V().count()",
"g.V().hasLabel('person').has('age', gt(40))",
"g.V().hasLabel('person').order().by('firstName', decr)",
"g.V('thomas').outE('knows').inV().hasLabel('person')",
"g.V('thomas').outE('knows').inV().hasLabel('person').outE('knows').inV().hasLabel('person')",
"g.V('thomas').repeat(out()).until(has('id', 'robin')).path()",
"g.V('thomas').outE('knows').where(inV().has('id', 'mary')).drop()",
"g.E().count()",
"g.V('thomas').drop()"
]
for (gremlin in gremlinQueries) {
ResultSet results = client.submit(gremlin);
CompletableFuture<List<Result>> completableFutureResults = results.all()
List<Result> resultList = completableFutureResults.get()
for (Result result : resultList) {
println(result.toString())
}
}
建設者創造和客戶端連接 - 當我在看的調試器，但是當我嘗試客戶端提交我得到以下堆棧跟蹤。

幾個想法，我有一個「familyDB」從以前的文件數據庫原型。但不能在用戶的建造者中找到gremlin配置方法來表示這一點。
進一步，如果你想從頭開始，爲圖的頂點等創建集合的當量創建DBS名
所以有沒有人有本地cosmossDB模擬器工作圖配置，並且我做了什麼錯/錯過導致此超時。它有一些簡單但我錯過了它。附件是拍攝調試器之前，我開始issueing客戶機命令預先
感謝
PS - 試圖從git的轂配置羣集作爲每個樣品中天青圖表拉鍊。
我的配置文件看起來像這樣
hosts: [localhost] port: 8081 username: /dbs/familyDB/colls/FamilyCollection password: C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw== connectionPool: { enableSsl: true} serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0, config: { serializeResultToString: true }} 而修改後的代碼來獲取連接現在讀
try {
File config = new File("D:/Intellij - Azure/quickstart-java/graph/src/main/cosmossDB-config.yaml")
assert config.exists()
Cluster.Builder builder = Cluster.build(config)
cluster = builder.create()
println cluster.dump()
} catch (FileNotFoundException e) {
e.printStackTrace()
return
}
，我已經從中返回以下
羣集實例甩了運行時的值prop: maxWaitForConnection, with value 3000 prop: nioPoolSize, with value 8 prop: keepAliveInterval, with value 1800000 prop: loadBalancingStrategy, with value class org.apache.tinkerpop.gremlin.driver.LoadBalancingStrategy$RoundRobin prop: resultIterationBatchSize, with value 64 prop: port, with value 8081 prop: serializers, with value [application/json] prop: maxInProcessPerConnection, with value 4 prop: maxWaitForSessionClose, with value 3000 prop: reconnectInterval, with value 1000 prop: workerPoolSize, with value 16 prop: minInProcessPerConnection, with value 1 prop: class, with value class org.apache.tinkerpop.gremlin.driver.Cluster prop: sslEnabled, with value true prop: maxContentLength, with value 65536 prop: serializer, with value org.ap[email protected]119020fb prop: factory, with value [email protected] prop: closing, with value false prop: channelizer, with value org.apache.tinkerpop.gremlin.driver.Channelizer$WebSocketChannelizer prop: closed, with value false
但是TimeoutExcption stil l發生。
我已經下載了gremlin控制檯，並試圖:remote connect，但是當我運行命令我得到這個，它警告沒有及時響應。

仍然卡住，不能得到這個工作 - 任何想法從cosmossDb仿真器的工作配置的人？
如果可以幫助任何人來回答 - 試圖通過conf文件，而不是在文件中讀取'主機打開集羣：[本地主機] 端口：8081 用戶名：/ DBS/familyDB/colls/FamilyCollection 密碼：C2y6yDjf5/R + ob0N8A7Cgv30VRDJIWEHLM + 4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/JW == 連接池：{ enableSsl：真正} 串行：{類名：org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0，配置：{serializeResultToString：真正}} ' –
