java - 创建名为 'sessionFactory' 的 bean 时出错 - 嵌套异常为 java.lang.NoClassDefFoundError :

Question

我是 Spring 新手，我按照教程从头开始创建项目。我发现 5 个帖子有类似问题，但帖子中的解决方案对我没有帮助。我两周无法解决这个问题，如果有人可以帮助我，我将非常感激。

Answer 1

好吧org/hibernate/boot/model/naming/ImplicitNamingStrategy ，据称缺失的肯定是 hibernate-core 的一部分您的 pom.xml 中具有哪些依赖项的库。

可能导致问题的一件事是包含:

    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.0-api</artifactId>
        <version>1.0.1.Final</version>
    </dependency>

因为您的版本 hibernate-core 具有此依赖性:

    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.1-api</artifactId>
        <version>1.0.0.Final</version>
    </dependency>

由于它们是不同的 Artifact ，因此它们都将包含在包中。

在 2.0 和 2.1 版本中使用 jpa api 可能会导致问题。
