问题描述
我想探索MongoDB的新事务功能并使用Spring Data MongoDB.但是，我收到异常消息该客户端连接到的MongoDB集群不支持会话".关于MongoDB 3.7.9的配置的任何提示都值得赞赏.
I want to explore the new transaction feature of MongoDB and use Spring Data MongoDB. However, I get the exception message "Sessions are not supported by the MongoDB cluster to which this client is connected". Any hint regarding the config of MongoDB 3.7.9 is appreciated.
stacktrace的开头是:
The stacktrace starts with:
com.mongodb.MongoClientException : 该客户端连接到的MongoDB集群 在com.mongodb.MongoClient.startSession(MongoClient.java:555)〜[mongodb-driver-3.8.0-beta2.jar:na] 在org.springframework.data.mongodb.core.SimpleMongoDbFactory.getSession(SimpleMongoDbFactory.java:163) 〜[spring-data-mongodb-2.1.0.DATAMONGO-1920-SNAPSHOT.jar:2.1.0.DATAMONGO-1920-SNAPSHOT]
com.mongodb.MongoClientException: Sessions are not supported by the MongoDB cluster to which this client is connected at com.mongodb.MongoClient.startSession(MongoClient.java:555) ~[mongodb-driver-3.8.0-beta2.jar:na] at org.springframework.data.mongodb.core.SimpleMongoDbFactory.getSession(SimpleMongoDbFactory.java:163) ~[spring-data-mongodb-2.1.0.DATAMONGO-1920-SNAPSHOT.jar:2.1.0.DATAMONGO-1920-SNAPSHOT]
推荐答案
当我尝试将其连接到单个独立的mongo实例时，我遇到了同样的问题，但是如
I was having the same issue when I was trying to connect it to a single standalone mongo instance, however as written in the official documentation, that Mongo supports transaction feature for a replica set. So, I then tried to create a replica set with all instances on MongoDB 4.0.0, I was able to successfully execute the code. So, Start a replica set (3 members), then try to execute the code, the issue will be resolved.
NB : you can configure a replica set on the same machine for tests https://docs.mongodb.com/manual/tutorial/deploy-replica-set-for-testing/
