我正在尝试访问@Service定义的类
@Service
public class TypeServiceImpl implements TypeService {
@Autowired
TypeDAO dao;
public List<DocType> findAll() {
System.out.println("accessing findAll"); //have no appearence
return dao.findAll();
}
公共类型daoimpl()
System.out.println(“构造类型DAOImpl”);
}
...
}
DAO的代码:
@Repository
public class TypeDAOImpl extends BaseDAO<Type, Long> implements TypeDAO{
}
BaseDAO:
public class BaseDAO<T, ID extends Serializable> extends GenericDAOImpl<T, ID> {
@Autowired
@Override
public void setSessionFactory(SessionFactory sessionFactory) {
super.setSessionFactory(sessionFactory);
}
}
generic dao
应用程序的配置加载正常(无警告或错误),但当我尝试使用该服务时:
@Autowired
private TypeService TypeService;
public void init() {
try {
for (Type d : TypeService.findAll()) {
System.out.println(d.getType());
}
} catch (Exception e) {
e.printStackTrace();
}
}
在applicationContext中:
<!-- Use annotations (@Autowired) for property injection -->
<context:annotation-config />
在日志中:

有什么建议吗?
