春季：由于名称java.lang.AbstractMethodError，创建名称为'entityManagerFactory'的bean时出错：null

标签： java spring

我在Spring中开发了一个简单的应用程序，我刚刚遇到了这个常见问题，但是由于其他原因中提到的那些由于某种原因而无法使用，因此我找不到解决方案。

该错误在我第一次运行该应用程序时触发，这就是它的含义：

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

这是我的休眠配置

# ===============================
# DATABASE
# ===============================

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql://localhost:3306/library
spring.datasource.username=root
spring.datasource.password=



# ===============================
# JPA / HIBERNATE
# ===============================

spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto = create
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect

我想做的是开发一个使用hibernate连接到xampp提供的mysql数据库的spring boot应用程序，但是这个错误使我很难受。

1 个答案:

答案 0 :(得分：0)

我在寻找更多答案后发现了问题。看起来像以下依赖项

<dependency>
    <groupId>org.jadira.usertype</groupId>
    <artifactId>usertype.core</artifactId>
    <version>3.0.0.CR1</version>
</dependency>

被包含与休眠框架冲突的输入。只需删除此依赖项，项目就可以正常工作。
