Spring Boot java.lang.NoClassDefFoundError

我的spring-boot应用程序出现问题，因为当我在下一个maven版本中使用Jar时无法启动它。但我可以在IDE中启动它...Spring Boot java.lang.NoClassDefFoundError

唯一的例外是：

java.lang.ClassNotFoundException: org.springframework.data.repository.CrudRepository

当我看着jar文件我有一个文件夹的lib /其中包含spring-boot-start-data-jpa-1.2.5.RELEASE.jar，所以我不明白为什么jar无法找到CrudRepository ...

任何想法？非常感谢您

将jar范围设置为'compile'？ – user

我对spring-boot-starter-data-jpa上的作用域编译有同样的问题。谢谢 –

我终于解决了我的问题。

我正在使用番石榴来查找所有通过@WebService注解的类，并且我创建了这个bean。但所有的bean都没有加载。所以我现在使用Spring停下来睡觉的ClassPathScanningCandidateComponentProvider来创建bean。

谢谢你的回答
