Spring data JPA Repository @autowired gives null

I've been trying out `spring-data-jpa`. With the help of Reference Documentation and my prior spring knowledge, I've set up spring-data-jpa configuration but the `Repository` that I `@Autowired` is always returned null. I've refer to other questions over here but I haven't figure out the solution. My ApplicationContext configuration is ``` @Configuration @EnableJpaRepositories("devopsdistilled.operp.server.data") @EnableTransactionManagement @PropertySource("server/jdbc.properties") @ComponentScan("devopsdistilled.operp.server.data") public class JpaContext { @Inject private Environment env; @Value("devopsdistilled.operp.server.data.entity") private String packagesToScan; @Bean public static PropertySourcesPlaceholderConfigurer getPropertySourcesPlaceholderConfigurer() { return new PropertySourcesPlaceholderConfigurer(); } @Bean public DataSource dataSource() { BasicDataSource dataSource = new BasicDataSource(); dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName")); dataSource.setUrl(env.getProperty("jdbc.url")); dataSource.setUsername(env.getProperty("jdbc.username")); dataSource.setPassword(env.getProperty("jdbc.password")); dataSource.setInitialSize(2); dataSource.setMaxActive(10); return dataSource; } @Bean public JpaVendorAdapter jpaVendorAdapter() { HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter(); jpaVendorAdapter.setDatabase(Database.MYSQL); jpaVendorAdapter.setGenerateDdl(true); jpaVendorAdapter.setShowSql(true); jpaVendorAdapter .setDatabasePlatform("org.hibernate.dialect.MySQL5Dialect"); return jpaVendorAdapter; } @Bean public LocalContainerEntityManagerFactoryBean entityManagerFactory() { LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean(); emf.setDataSource(this.dataSource()); emf.setJpaVendorAdapter(this.jpaVendorAdapter()); emf.setPackagesToScan(packagesToScan); emf.setJpaProperties(this.hibernateProperties()); return emf; } @Bean public JpaDialect jpaDialect() { return new HibernateJpaDialect(); } @Bean public JpaTransactionManager transactionManager() { JpaTransactionManager transactionManager = new JpaTransactionManager(); transactionManager.setEntityManagerFactory(entityManagerFactory() .getObject()); transactionManager.setJpaDialect(jpaDialect()); return transactionManager; } @Bean public Properties hibernateProperties() { Properties hibernateProps = new Properties(); hibernateProps.setProperty("hibernate.hbm2ddl.auto", "create"); return hibernateProps; } @Bean public PersistenceExceptionTranslationPostProcessor exceptionTranslationPostProcessor() { return new PersistenceExceptionTranslationPostProcessor(); } } ``` My Entity definition is as follows ``` @Entity public class Item implements Serializable { private static final long serialVersionUID = 7751126479626962944L; private Long id; private String name; @Id @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return new String("Id: " + getId() + "\nName: " + getName()); } } ``` ` My Repository definition is as follows ``` @Repository public interface ItemRepository extends JpaRepository { } ``` ` While I try to run a sample application as follows ``` public class ServerApp { @Inject ItemRepository itemRepository; public static void main(String[] args) { ApplicationContext context = new AnnotationConfigApplicationContext( JpaContext.class); new ServerApp().sampleMethod(); System.out.println(context); } public void sampleMethod() { Item item = new Item(); item.setName("Test Item"); item = itemRepository.save(item); System.out.println(itemRepository.findOne(item.getId())); System.out.println("From sampleMethod"); } } ``` ` I get the following output in console. ``` SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

I've written a Test for the Repository as follows. ``` @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = JpaContext.class) @Transactional public class ItemRepositoryTest { @Inject private ItemRepository itemRepository; private Item item; @Before public void setUp() throws Exception { item = new Item(); item.setName("Test Item"); } @Test public void testSave() { item = itemRepository.save(item); Assert.assertEquals(item, itemRepository.findOne(item.getId())); } } ``` ` What is missing in my configuration? How can I solve this problem? Thanks
