spring-data-jpa Repository @Autowired throw exception

[Shishir.Kumar]

I am trying to using spring-data-jpa version 1.0.0.M2. When I am trying to @Autowired Repository I am getting BeanCreationException (Nested exception EntityManagerFactoryImpl.getMetamodel()).

Below is code snippet (Entity, Repository, Controller and applicationContext.xml):

/**
* POJO class for user login information.
* @author SKumar
*/
@Table(name = "USER_LOGIN")
@Entity
public class UserLogin {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.TABLE)
@Column(name = "USER_ID")
private Long id;
.
.
.
}


package com.campaignify.repository;

import org.springframework.data.jpa.repository.JpaReposit ory;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transac tional;

import com.campaignify.entity.UserLogin;
@Transactional
@Repository
public interface UserLoginRepository extends JpaRepository<UserLogin, Long>{
}

@Repository
@Controller
@RequestMapping("/user")
@Transactional()
public class UserManagementController {

@Autowired
UserLoginRepository userRepository;

@RequestMapping(method = RequestMethod.POST)
@Transactional(readOnly = false)
public View saveUser(@RequestBody UserLogin user) {
View returnView = new RedirectView("/user/");
try {
userRepository.save(user);
returnView = new RedirectView("/user/" + user.getId());
} catch (Exception e) {
// TODO Exception handling here.
e.printStackTrace();
}
return returnView;
}
}

@Autowired should have worked as I have defined repositories base package and component-scan. Spring should create proxy implementation of UserLoginRepository and inject within controller. Please help what I am missing.

<jpa:repositories base-package="com.campaignify.repository" />
<context:component-scan base-package="com.campaignify" use-default-filters="false"/>

1. Please use the CODE tag
2. you should remove @Transactional and @Repository from UserLoginRepository
3. Error => nested exception is java.lang.AbstractMethodError: org.hibernate.ejb.EntityManagerFactoryImpl.getMeta model()Ljavax/persistence/metamodel/Metamodel; Which hibernate version do you use? Which persistence.jar file is in your classpath?

[Oliver Gierke]

I second GWA. The exception says you're lacking metamodel related methods on the EntityManager. Make sure you're using JPA and a Hibernate version that supports JPA 2.0 (Hibernate 3.5 or higher).

[Shishir.Kumar]

Point 1#: Where to use code tag? (I am currently testing sample by RESTClient)
Point 2#: Earlier I had UserLoginRepository without @Transactional, @Repository annotation. I added with asumption that we may need separate transaction at Repository layer independent of service\controller transaction. Tried again removing annotation but no luck.
Point 3#:
Below are hibernate dependency:

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>3.3.2.GA</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.4.0.GA</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.4.0.GA</version>
</dependency>


Persistance: ejb3-persistence-1.0.2.GA.jar
hibernate-jpa-2.0-api-1.0.0.Final.jar

I can see spring-data-jpa-1.0.0.M2.pom using hibernate.version 3.6.0.Final for hibernate-entitymanager (not presently on apache Maven repository).

[Oliver Gierke]

Hibernate 3.4.0 does *not* support JPA 2.0… So you've got to use 3.5 or higher.

[Shishir.Kumar]

Thanks for pointer.

Pointing hibernate version to 3.5.1-Final solved the issue.

I am getting an exception from Spring Data Jpa 1.0.0.M2 like this:

Caused by: java.lang.AbstractMethodError: org.springframework.data.repository.support.Reposi toryFactorySupport.getRepositoryBaseClass(Lorg/springframework/data/repository/support/RepositoryMetadataLjava/lang/Class;

<dependency>

<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.0.Final</version>
</dependency>

Thanks a lot for any ideas that might help!

[gwa]

Please use CODE tag!

Like say in the previous reply, spring-data-jpa need a jpa2 provider.

If you use hibernate, you need to use a v3.5+

In your dependency you have:

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>3.6.3.Final</version>
</dependency>
...
<dependency>
<groupId>hibernate-entitymanager</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.3.2.GA</version>
</dependency>

The entitymanager dependency is the hibernate jpa integration. Here you use 3.3 version which is outdated (JPA1)

As hibernate-core is a dependency of hibernate-entitymanager simply remove the hibernate core dependency and update entitymanager version to 3.6.3.Final.

[Oliver Gierke]

I second GWA's answer but his hint is probably not solving your issue. It seems you have a non-suitable version of Spring Data Commons Core in your classpath. Spring Data JPA M2 needs Spring Data Commons Core in M5 (as stated by the pom.xml).

Cheers,
