I am trying to implement a solution using a combination of eclipselink (2.4.0) and spring-data-jpa (1.1.0.RELEASE). However, every time I deploy the solution (Tomcat 7), I get the following exception:
Caused by: java.lang.IllegalArgumentException: No [ManagedType] was found for
the key class [com.acme.domain.entities.User] in the Metamodel - please
verify that the [Managed] class was referenced in persistence.xml using a
specific <class>com.acme.domain.entities.User</class> property or a global
<exclude-unlisted-classes>false</exclude-unlisted-classes> element.
It appears to occur when the repository autowiring takes place (code examples below):
Service class
@Component
public class UserDataService {
@Autowired
private UserRepository userRepository;
...
}
Entity class
package com.acme.domain.entities;
...
@Entity
@Table(name = "users")
public class User implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "user_id")
private Integer id;
...
}
persistence.xml
<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.acme.domain.entities.User</class>
...
</persistence-unit>
Can this be due to some conflict between spring and eclipselink?
UPDATE:
