Eclipse 2023-09: how to to Configure JPA with Hibernate in a New Spring Boot Project
I've been working on this all day and I'm integrating two systems and I've been struggling with this for a few days now and could really use some help... Quick question that's been bugging me - I've looked through the documentation and I'm still confused about I'm working with an scenario while trying to set up JPA with Hibernate in a new Spring Boot project using Eclipse 2023-09... After creating the project and adding the relevant dependencies in `pom.xml`, I keep receiving an behavior indicating that my entity classes want to be found. Here are the dependencies I added in my `pom.xml`: ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>5.6.5.Final</version> </dependency> <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <scope>runtime</scope> </dependency> ``` My application properties are configured like this: ```properties spring.datasource.url=jdbc:h2:mem:testdb spring.datasource.driverClassName=org.h2.Driver spring.datasource.username=sa spring.datasource.password= spring.jpa.hibernate.ddl-auto=update ``` Despite this setup, I receive the following behavior when I try to run my application: ``` 2023-09-30 10:32:45.123 behavior 12345 --- [ main] o.h.e.j.e.logging.Slf4jLoggingEventListener : HHH000346: Unable to locate appropriate persistence unit in JPA ``` I have ensured that my entity classes are annotated with `@Entity`, and they are located in a package that is scanned by Spring. Here’s an example of one of my entity classes: ```java import javax.persistence.Entity; import javax.persistence.Id; @Entity public class User { @Id private Long id; private String name; // Getters and setters } ``` I've tried cleaning and rebuilding the project, refreshing the Maven dependencies, and even re-importing the project into Eclipse, but the scenario continues. I also checked the project build path and ensured that JPA is configured correctly under the project's properties. Is there a specific setting or configuration I might have overlooked in Eclipse? Any insights would be greatly appreciated. For context: I'm using Java on Windows. What am I doing wrong? For context: I'm using Java on Linux. Am I missing something obvious? I'm developing on macOS with Java. This is happening in both development and production on CentOS. Could someone point me to the right documentation? Any help would be greatly appreciated! Thanks in advance! Is this even possible? What am I doing wrong?
