我正在尝试将我的spring boot应用程序连接到在Docker容器中运行的mongodb实例。 在端口21017暴露的情况下启动容器
docker run -p 21017:21017 --detach --name some_name bitnami/mongodb:latest
在aplication.properties中，我有以下设置
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
但是当我启动该应用程序时，我遇到了异常
019-06-20 15:58:07.364 INFO 58145 --- [localhost:27017] org.mongodb.driver.cluster : Exception in monitor thread while connecting to server localhost:27017
