我正在使用Spring Tool Suite練習Spring。我一直在試圖將我的項目連接到數據庫。向Spring項目添加「spring-boot-starter-data-jpa」依賴項時出錯
但是，每當我將「spring-boot-starter-data-jpa」依賴項添加到pom.xml時，項目將無法啓動，並且出現以下錯誤。一旦我刪除依賴關係，錯誤不會發生。我不知道他們爲什麼發生。這裏有以下錯誤：
org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatEmbeddedServletContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'serverProperties' defined in class path resource [org/springframework/boot/autoconfigure/web/ServerPropertiesAutoConfiguration.class]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/HibernateException

我試圖更新Maven和驗證項目，但錯誤依然存在。
嘗試'mvn dependency：purge-local-repository'，將重新下載（在下一個版本中）所有的依賴關係。而不是'hibernate-validator'使用'spring-boot-starter-validation'，而不是'com.sun.mail'依賴使用'spring-boot-starter-mail'依賴。 –
清除maven緩存似乎使程序工作。謝謝！ –
