老师你好，整合完了 启动服务报了mongoDB的错MongoSocketOpenException，但是好像服务并没有受影响，网页也能正常显示，怎么才能消除这条报错呢？在我们的源码里有哪边用到了mongodb来着

log是这样的：2023-01-06 21:44:50.701 INFO 32965 — [ main] com.imooc.Application : Starting Application using Java 1.8.0_331 on SuhandeMBP.lan with PID 32965 (/Users/suhanlu/IdeaProjects/imooc-red-book-dev/book-api/target/classes started by suhanlu in /Users/suhanlu/IdeaProjects/imooc-red-book-dev)
