我也是這樣

java.lang.IllegalStateException: Found multiple @SpringBootConfiguration annotated classes [Generic bean: class [com.neo.demo.HelloApplication]; scope=; abstract=false; lazyInit=null; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in file [F:\QMDownload\mail\spring-mail\target\classes\com\neo\demo\HelloApplication.class], Generic bean: class [com.neo.demo.MailApplication]; scope=; abstract=false; lazyInit=null; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in file [F:\QMDownload\mail\spring-mail\target\classes\com\neo\demo\MailApplication.class]]

我也出現了跟你一樣的錯誤

能把代碼跟錯誤信息描述的詳細一些么
