NoClassDefFoundError. :创建名称为bean的错误 'entityManagerFactory'

NoClassDefFoundError. : Error creating bean with name 'entityManagerFactory'

也许您知道我应该在pom.xml中包括哪个依赖项. Maven项目. 这是我所拥有的:

Maybe you know which dependency I should include to my pom.xml. Maven project. here is what i have:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>

    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.apache.derby</groupId>

</dependencies>

推荐答案

hibernate-core和hibernate-entitymanager通过spring-boot-starter-data-jpa

已编辑:您可以先尝试删除本地.m2/repository吗?有时它会损坏.

Edited: Could you first try removing you local .m2/repository? Sometime it gets corrupted.

rm -rf ~/.m2/repository

您能包括使用pom.xml内容的哪个Spring Boot版本吗?

Could you include which Spring Boot version are you using pom.xml content.

您还可以包括数据源和JPA属性吗?

Could you also include you data source and JPA properties?
