Java 在spring boot App中删除mongo依赖项后，连接到服务器localhost:27017时监视器线程中出现异常

我开始使用一个有mongoDB连接的spring boot应用程序，但之后就没有必要了，所以我从代码、存储库、pom.xml、docker文件等中删除了所有依赖项。但当我启动spring boot应用程序时，我遇到了下一个异常：

我不知道我为什么会遇到这个问题，似乎连接在应用程序的某些历史记录中，但我删除了它所在的所有位置，在mvn清理安装/打包并重新创建docker映像后，我遇到了这个问题

这是我的pom.xml依赖项：

        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>

我的代码中没有存储库，也没有对mongo连接的任何引用，有什么想法吗？

调用了

com.mongodb.internal.connection.SocketStream.open

吗？

FROM adoptopenjdk/openjdk11:alpine-jre
