@Configuration

        factory.setDataSource(dataSource());//设置数据据

    }DAO:@Repository("SQLiteDao")
public class SQLiteDaoImpl implements SQLiteDao {
    @Autowired
    private SessionFactory sessionFactory;
    启动报错:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=sessionFactory)}
请问怎样在DAO层注入进来。
