spring上下文未加载上下文文件

我正在创建一个基于spring的web项目，我的文件如下。
应用程序上下文.xml

<beans xmlns="http://www.springframework.org/schema/beans"

网站.xml

</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

这是tomcat启动时出现的错误，

org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/<filename>.properties]

由于applicationcontext.xml没有初始化，spring没有初始化bean，因此我无法使用这些bean。请帮忙。为什么上下文加载器试图加载不正确的文件？
仅供参考，我使用的是spring 4.1.6.release。这也是一个maven项目。
编辑，以便在ike建议将类路径添加到占位符文件后修复该问题。但spring上下文尚未初始化。自动连线属性仍为空。但根据日志，spring试图使用上下文文件中提到的sessionfactory连接mysql。

                return Response.status(Status.BAD_REQUEST).entity("Bad request").build();
            }

            String searchQuery = inputJson.getString("keyword");

            List<City> cities = cityDAO.searchCities(searchQuery);

            return Response.status(Status.OK).entity(cities).build();               
        }
        else {
            return Response.status(Status.BAD_REQUEST).entity("Bad request").build();
        }
    }
}

dao接口

public interface CityDAO {
    public List<City> searchCities(String searchQuery);
}

dao impl类

@Repository

    public class CityDAOImpl implements CityDAO {

        @Autowired
        private SessionFactory sessionFactory;

        @SuppressWarnings("unchecked")
        @Override
        @Transactional
        public List<City> searchCities(String searchQuery) {
            Session session = sessionFactory.getCurrentSession();
            Query query = session.createQuery("from "+ City.class.getName() + " where "
                    + "city_name like '%"+searchQuery+"%' OR city_airline_code like '%"+searchQuery+"%'");
            return query.list();
        }
    }

上下文基包标记-

<context:component-scan base-package="com._._.dao" />

com…dao是citydao所在的包。正在获取空指针异常 List<City> cities = cityDAO.searchCities(searchQuery); 这意味着自动布线没有发生。
编辑3向jersey服务类添加@component注解解决了以下问题：）
谢谢@ike3的帮助。
