I'm pretty new to Hibernate/JPA. Running the application, I'm getting this error:
Consider defining a bean named 'entityManagerFactory' in your configuration.
The main class (I use @EnableJpaRepositories to let Spring find the repository in other package):
@SpringBootApplication
@EnableJpaRepositories
public class RunApp {
public static void main(String[] args) {
SpringApplication.run(RunApp.class, args);
}
}
My main entity class:
@Entity(name = "User")
@Table(name = "users")
@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {
@Id
@GeneratedValue
private Long id;
private String name;
private Integer age;
private String email;
}
A repository:
@Repository
public interface UserRepository extends CrudRepository<User, Long> {
}
A properties file:
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/mydbtest
spring.datasource.username=root
spring.datasource.password=123123
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

What should I do here?
CodePudding user response:
Try using spring-boot-starter-data-jpa
instead of spring-data-jpa
CodePudding user response:
Change dependency
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>2.7.1</version>
</dependency>
to this
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
CodePudding user response:
I solved this adding the following dependency instead of spring-data-jpa:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>2.7.1</version>
</dependency>
After that, I got this exception:
Error creating bean with name 'entityManagerFactory' defined in class path resource
But simply solved it by adding this dependency:
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>
