运行jar但从IDE正常工作时出现Spring Boot错误（Spring boot starter data jpa）

Question

**编辑：当我使用gradle而不是maven它工作正常！，我从start.spring.io生成我的项目

**Edit2:my pom.xml

当我从eclipse ide运行我的代码时，它工作正常，但当我将项目打包为. jar并从命令行运行时，它显示此错误，如果我从依赖项中删除spring-boot-starter-data-jpa，它工作正常。

抱歉回答晚了。这对像我这样带着这个问题来这里的人会有所帮助。

我在pom中有spring-boot-starter-data-jpa依赖项，但没有带有@Entity注释的实体，在下面添加修复了问题，如评论部分建议的那样

@EnableAutoConfiguration(exclude = HibernateJpaAutoConfiguration.class)

或

spring.data.jpa.repositories.enabled=false

Spring Boot版本1.4.0
