One of the words is that

{address=127.0.0.1:27017, type=replica_set_secondary, roundtriptime=1.3 MS, state=connected}

It means 127.0.0.1:27017. This server is a Secondary,mongo driver that cannot write data to the secondary node, suspected MONGO primary and secondary switching.

Later the login MONGO server found that there was indeed a primary and secondary switch.

And then back to the program found that the colleague link MONGO code as follows,

Spring.data.mongodb.uri=mongodb://127.0.0.1:27017/quezon

I rub, only linked to a MONGO, happened to be online when the node happens to be primary node, now occurred primary and secondary, so the error, adjusted MONGO link string below,

Spring.data.mongodb.uri=mongodb://127.0.0.1:27017,127.0.0.1:27018,127.0.0.1:27019/quezon?replcaset=spock

Where Replcaset specifies the name of the replica set, reboot, OK.
