Configuration problem: org.springframework.data.jpa.repository.config.Jpa Repositories

[Jenseman]

I am building a simple web application using:

• Eclipse
• Spring webmvc
• Spring data
• Hibernate

So far I have successfully created a very simple webapp capable of presenting a list of things to do. The list is retrieved from a simple service and all is wired together using annotations.

Now - I would like to have my simple service actually fetch the things to do from a database.

Using Spring data I have been able to build entity, repository and configuration classes and I can use them to fetch data from the database and print it out to the console. But only when run stand-alone.

As soon as my config class is visible to <context:component-scan> I get an error from my embedded TomCat:

Configuration problem: org.springframework.data.jpa.repository.config.Jpa RepositoriesRegistrar was @Import'ed but is not annotated with @Configuration nor does it declare any @Bean methods. Update the class to meet one of these requirements or do not attempt to @Import it.

I have nailed the problem down to the @EnableJpaRepositories in the config class. The definition of this annotation includes @Import(value={JpaRepositoriesRegistrar.class}):

package myproj.configs;

import javax.persistence.EntityManagerFactory;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.dao.support.PersistenceExceptionTranslator;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.data.jpa.repository.support.JpaRepositoryFactory;
import org.springframework.data.repository.core.support.RepositoryFactorySupport;
import org.springframework.orm.hibernate3.HibernateExceptionTranslator;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaDialect;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@Import(MyDataSource.class)
@EnableTransactionManagement
@EnableJpaRepositories("myproj")
public class MyConfig {
    
    @Bean
    public EntityManagerFactory entityManagerFactory() {

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(false);

        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan(new String[] {"myproj"});
        factory.setDataSource(MyDataSource.myDataSource());
        factory.afterPropertiesSet();

        return factory.getObject();
    }
    ...

I have been searching the web for similar problems for the last two days without success.

Can anyone help?

Please let me know if I need to supply additional information or source code.

How are you executing the code? Are you using a JUnit test? I just finished posting examples of this config here: https://github.com/gordonad/core-spr...orms/hibernate

Let me know if you are still stuck.

Hi Gordon,

I do use JUnit but I havent implemented any tests yet.

I dont really execute as such. The presence of the @EnableJpaRepositories immediatly breaks the automatic republishing of my servlet to Tomcat. The stackdump is from the Tomcat console output.

I will revert when I have tried out your congiguration. Thanks:-)

Best regards

Hi Jens,

I moved the repository to https://github.com/gordonad/spring-data-demos

I will be adding to this the annotation config for a web app for the next commit.


Sorry for the confusion.

Hi Gordon,

Its no problem - I found it - it didn't solve my problem though.

But yesterday afternoon a colleague of mine came to my rescue helping me sort out my dependencies. It turned out to be related to me trying to run spring-data 1.2.0 with spring-other-stuff 3.1.0.

I have upgraded my project to spring 3.2.0.RELEASE and the problem has gone. Unfortunately I haven't been able to reproduce it afterwards, so I cant say exactly how it came about.

But anyways - a YALVMI (Yet Another Library Version Mismatch Issue).

Thanks a lot for you effort.
