[Inquiry] Spring Setup using @Configuration

Good Day,

I have been reading and trying out the samples provided in the http://blog.springsource.org but I'm block by an error that I'm not familiar with.

Quote:

---

[main] ERROR o.s.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'dataSource' defined in class path resource [org/config/DataConfig$Embedded.class]: No matching factory method found: factory bean 'dataConfig.Embedded'; factory method 'dataSource()'. Check that a method with the specified name exists and that it is non-static.

Given the following code:

Code:

---

@Configuration
public class DataConfig {

    @Inject
    private DataSource dataSource;

    @Inject
    private EntityManagerFactory entityManagerFactory;

    @Bean
    public EntityManagerFactory entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactory.setDataSource(dataSource);
        entityManagerFactory.setPersistenceProvider(new HibernatePersistence());
        return entityManagerFactory.getObject();
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager(entityManagerFactory);
        transactionManager.setDataSource(dataSource);
        transactionManager.setJpaDialect(new HibernateJpaDialect());
        return transactionManager;
    }

    @Configuration
    @Profile("embedded")
    static class Embedded {

        @Bean
        public DataSource dataSource() {
            return new EmbeddedDatabaseBuilder().setType(H2).build();
        }
    }
}

Here is a snippet of the web.xml

Code:

---

<context-param>
  <param-name>contextClass</param-name>
  <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</context-param>

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>org.config</param-value>
</context-param>

<context-param>
  <param-name>spring.profiles.default</param-name>
  <param-value>embedded</param-value>
</context-param>
