解决 java.lang.AbstractMethodError，在 Spring 中创建名为“entityManagerFactory”的 bean 时出错

Question

我正在尝试让我的项目将 MySQL 与 JPA 一起使用。每次我将 JPA 依赖项添加到 mu pom.xml 时，都会出现以下错误。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.AbstractMethodError

这是我的 pom.xml 的样子

我已经尝试过类似问题的解决方案 Error creating bean with name 'entityManagerFactory

Error creating bean with name 'entityManagerFactory' defined in class path resource 不适合我。

Answer 1

您收到错误是因为您遇到了类路径问题。 使用 ecipe 打开 pom.xml 并转到依赖层次结构并搜索 hibernate 的版本。

应该只有一个版本。

Answer 2

通过删除下面的依赖项，问题得到解决

    <!-- <dependency>
       <groupId>org.jadira.usertype</groupId>
       <artifactId>usertype.core</artifactId>
       <version>4.0.0.GA</version>
    </dependency> -->

Answer 3

AbstractMethodError 通常表示类路径包含不兼容的依赖项。

这是所有人都面临的主要问题。因为有时我们在 Parent pom 中管理版本，突然对于某些测试场景，我们将添加与现有版本不兼容的版本的直接依赖关系。

Answer 4

我们在 hibernate spring mvc 程序中遇到了相同类型的错误。后来我们意识到库中有两个不同版本的 spring 导致错误。 “AbstractMethodError”是正确的不兼容依赖项。
