在同一個tomcat中啟動了多於1個的springboot專案，並且資料來源的配置使用的是springboot方式做的。
解決方案：
1.如果是同一個專案，把專案放置在tomcat的webapps目錄下，同時配置了程式路徑<Context path="" docBase="/tomcat/webapps/projectFolder" debug="0" reloadable="false" crossContext="true" useRelativeRedirects="false"/>。那麼兩者選一，或者刪除後者配置，或者轉移前者至其他目錄，並把後者配置的路徑指向該目錄。
2.如果是不同的專案，網上搜到說在application.properties中配置spring.jmx.enabled=false
