MongoDB重新启动后，为什么Java App会失去连接？

Question

The MongoDB is in a replica set with three members. Sometimes one or two MongoDB instances restarted, the Java Apps lose connection and show the following error and then I have to restart the Java Apps manually so as to re-connect the MongoDB replica set:

org.springframework.dao.DataAccessResourceFailureException: 
Unable to connect to any server that matches 
{serverSelectors=[ReadPreferenceServerSelector{readPreference=secondaryPreferred}, 
LatencyMinimizingServerSelector{acceptableLatencyDifference=15 ms}]}; 
nested exception is com.mongodb.MongoServerSelectionException: 
Unable to connect to any server that matches 
{serverSelectors=[ReadPreferenceServerSelector{readPreference=secondaryPreferred}, 
LatencyMinimizingServerSelector{acceptableLatencyDifference=15 ms}]}

I would like to know are there any solutions to keep the connectivity even if the MongoDB instances restarted? Thank you so much.

Thank you so much. I fixed the problem by changing the configuration of spring data. I set socket-timeout="1500" before. I should not set socket timeout. Defaults to 0 (infinite time).
