I am writing Junit test case for my Spring boot application but I am getting following error when I run the tests:

java.lang.IllegalStateException: Failed to load ApplicationContext Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'entityManagerFactory' threw exception; nested exception is java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/CamelCaseToUnderscoresNamingStrategy Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'entityManagerFactory' threw exception; nested exception is java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/CamelCaseToUnderscoresNamingStrategy Caused by: java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/CamelCaseToUnderscoresNamingStrategy Caused by: java.lang.ClassNotFoundException: org.hibernate.boot.model.naming.CamelCaseToUnderscoresNamingStrategy

I have spent good amount of time trying to figure out where things are going wrong but to no avail. Any pointer what can i do to fix this error. Here are the environment details:

Java - 11, Spring boot - 2.6.7

I have already added following in pom.xml

<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>

I had following dependencies in pom.xml, which I removed after going through couple of suggestions:

<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>

Complete pom.xml.In my project, some dependencies come from parent project. For simplicity, I have merged the contents of both parent and child pom and shared below.

  • Seems like this could help: stackoverflow.com/questions/32519332/… tldr- check if you have different versions clashing with each other in your dependency chain. Commented Nov 29, 2022 at 16:08
  • Please show the whole pom.xml Commented Nov 29, 2022 at 16:15
  • Already tried the suggestion in the link. Didn't work for me. Commented Nov 29, 2022 at 16:16
  • @SimonMartinelli Added contents from pom.xml Commented Nov 29, 2022 at 16:25
  • Can you please test case for which this error is coming and project folder structure. Commented Nov 29, 2022 at 17:21

I managed to solve the problem by adding following dependencies to pom.xml

<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

Class is present in hibernate-core 5.6.14. Once, i used the correct version, this problem was solved.
