我正在使用Spring Boot 2.0.3和MongoDB。我需要在应用程序中连接到2个数据库。每个数据库都有自己的副本集。我没有使用 application.properties 中的默认 spring.data.mongodb.uri 属性连接到这些数据库。我使用具有以下连接URI的MongoTemplate配置bean创建了2个单独的数据源：
mongodb.db1.uri=mongodb://user1:password@18.220.X.X:27017,18.222.X.X:27017,18.223.X.X:27017/db1?authSource=db1
mongodb.db2.uri=mongodb://user2:password@18.188.X.X/db2?authSource=db2
我正在尝试通过提供Spring documentation中提到的辅助实例的公共ip来配置上述第一个URI中的副本集。但是每当我尝试使用它进行连接时，它就会超时并抛出以下异常。
当您仅在连接URI中提供主实例时，它可以很好地工作。
