I can't get spring working. Somebody can help me? In this sample I have 2 autowiring: CvDaoImpl and SessionFactory. Both doesn't recognized in context and returns null.
CvQuery.java
package service;
@Service
public class CvQuery {
@Autowired
private CvDao cvDao;
private String query;
@Transactional
public List<User> getUsers() {
return cvDao.getUsers(query);
}
...getters/setters
}
CvDaoImpl.java
package dao;
@Repository
public class CvDaoImpl implements CvDao {
@Autowired
private SessionFactory sessionFactory;
@Override
public List<User> getUsers(String query) {
Session currentSession = sessionFactory.getCurrentSession();
Query<User> theQuery = currentSession.createQuery(query, User.class);
return theQuery.getResultList();
}
public CvDaoImpl() {
}
}
And here is configuration.

DataSourseConfig.class
package configuration;
@Configuration
@PropertySource("classpath:persistence-mysql.properties")
@EnableTransactionManagement
public class DataSourceConfig {
@Autowired
private Environment env;
@Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan("entity");
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
}
I'm using intellij idea so if configuration is correct, maybe some settings in project structure are wrong. spring_config.xml is attached as spring application context on Modules section.
Added:
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("spring_config.xml");
....
}
application context should be create here
Upd I've tried to use objects from simple Java classes and from beans. Different contexts - that was a problem.
