application.xml文件加载了，但是DAO层方法获取不到sqlsession，下面是代码

web.xml

<display-name>mybatis</display-name>

	<welcome-file-list>

		<welcome-file>index.jsp</welcome-file>

	</welcome-file-list>



	<context-param>

		<param-name>contextConfigLocation</param-name>

		<param-value>/WEB-INF/applicationContext.xml</param-value>

	</context-param>



	<listener>

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

	</listener>



	<servlet>

		<servlet-name>spring</servlet-name>

		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

	</servlet>

	<servlet-mapping>

		<servlet-name>spring</servlet-name>

		<url-pattern>*.do</url-pattern>

	</servlet-mapping>

applicationContext.xml

	<bean id="test" class="com.leq.beans.Test">

		<property name="title" value="aa"></property>

		<property name="body" value="bb"></property>

	</bean>

Dao方法

@Repository

public class NewsDaoImpl extends SqlSessionDaoSupport implements NewsDao {

	

	

//	@Resource

	private Test test;



	public Test getTest() {

		return test;

	}

	@Resource  

	public void setTest(Test test) {

		this.test = test;

	}

//	@Resource

	private SqlSessionFactory ssf;

//	@Resource

//	private SqlSessionTemplate sst;

//	public SqlSessionTemplate getSst() {

//		return sst;

//	}

//	public void setSst(SqlSessionTemplate sst) {

//		this.sst = sst;

//	}

//	@Resource

	private BasicDataSource bds;

	

	

	public BasicDataSource getBds() {

		return bds;

	}

	@Resource  

	public void setBds(BasicDataSource bds) {

		this.bds = bds;

	}

	@Resource  

    public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){  

        super.setSqlSessionFactory(sqlSessionFactory);  

        

    }  

    public void getSqlSessionFactory(SqlSessionFactory sqlSessionFactory){  

        super.getSqlSession();

    }  

	@Override

	public Object getNewsInfo(int id) throws Exception {

		System.out.println("test ..."+test);

		System.out.println("ssf ..."+ssf);

		System.out.println("BasicDataSource ..."+bds);

		return null;

	}



}

下面的是日志，日志上面有加载applicationcontext.xml，但是DAO方法获取不到，是不是我写错了？？？有高手告诉一下吗
