SpringBoot测试-创建名为“entityManagerFactory”的bean时出错
SpringBoot测试-创建名为“entityManagerFactory”的bean时出错
提问于 2022-11-29 16:03:01
我正在为我的Spring引导应用程序编写Junit测试用例，但在运行测试时会遇到以下错误：
org.springframework.beans.factory.BeanCreationException:错误创建名为'entityManagerFactory‘的bean，类路径资源org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class: Bean通过工厂方法实例化失败；嵌套异常是org.springframework.beans.BeanInstantiationException:无法实例化org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean:工厂方法'entityManagerFactory’抛出的异常；嵌套异常是由: org/hibernate/boot/model/naming/CamelCaseToUnderscoresNamingStrategy引起的: org.springframework.beans.BeanInstantiationException:未能实例化org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean:工厂方法'entityManagerFactory‘抛出的异常；嵌套异常是java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/CamelCaseToUnderscoresNamingStrategy引起的: java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/CamelCaseToUnderscoresNamingStrategy引起的: java.lang.ClassNotFoundException: org.hibernate.boot.model.naming.CamelCaseToUnderscoresNamingStrategy
我花了很多时间试图找出哪里出了问题，但没有结果。任何指针，我能做什么来修复这个错误。以下是环境细节：
Java-11，Spring 2.6.7
我已经在pom.xml中添加了以下内容
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>我在pom.xml中有下面的依赖项，经过几个建议之后，我删除了这些依赖项：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.5.0.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.5.0.Final</version>
</dependency>完成pom.xml.In我的项目，一些依赖项来自父项目。为了简单起见，我合并了父级和子级pom的内容，并在下面进行了共享。

通过向pom.xml添加以下依赖项，我设法解决了这个问题
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.6.14.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.6.14.Final</version>
</dependency>
<!-- https://mvnrepository.com/artifact/dom4j/dom4j -->
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>1.6.1</version>
</dependency>org.hibernate.boot.model.naming.CamelCaseToUnderscoresNamingStrategy
类存在于hibernate-core 5.6.14中。有一次，我用了正确的版本，这个问题解决了。
