springmvc整合mybatis时，获取不到sqlsession

[刘大神仙]

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

<!-- 配置jdbc文件的位置 -->
	<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations" value="classpath:jdbc.properties"></property>
	</bean>
	
	<!-- 配置数据源 -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" init-method="">
		<property name="driverClassName" value="${driver}"></property>
		<property name="url" value="${url}"></property>
		<property name="username" value="${username}"></property>
		<property name="password" value="${password}"></property>
	</bean>
	
	<!-- mybatis在spring中的bean配置 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="configLocation" value="classpath:sqlMapConfig.xml"></property>
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
		<constructor-arg index="0" ref="sqlSessionFactory"></constructor-arg>
	</bean>
	
	<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

你用@Resource要在spring-mvc打开注解加上 <mvc:annotation-driven/> 你试试再加上这个 <bean id="sqlSession" scope="prototype" factory-bean="sqlSessionFactory" factory-method="openSession"> </bean> 这个是自动扫描com.tarena包及其子包，将所有扫描到的Mapper接口都创建Bean对象 你有包的话可以参考下 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.tarena"/> <property name="annotationClass" value="com.tarena.entity.MapperBean"/> </bean>
