Spring整合Myabtis注入失败.求解答

[colie_li]

配置文件:

	<!-- 1. 数据源 : DriverManagerDataSource -->
	<context:component-scan base-package="com.springmvc.dao" />  
	<bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
		<property name="url" value="jdbc:mysql://localhost:3306/mybaitis"/>
		<property name="username" value="root"/>
		<property name="password" value="root"/>
	</bean>
	
	<!-- 
		2. mybatis的SqlSession的工厂: SqlSessionFactoryBean 
			dataSource / typeAliasesPackage
	-->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="datasource"/>
		<property name="typeAliasesPackage" value="com.springmvc.mybaitsmodel"/>
	</bean>

	<bean id="session" class="org.mybatis.spring.SqlSessionTemplate">
		<constructor-arg index="0" ref="sqlSessionFactory" />
		<!-- <constructor-arg index="1" value="BATCH" />如果想要进行批量操作可加入这个属性 -->
	</bean>
	<!-- 
		3. mybatis自动扫描加载Sql映射文件 : MapperScannerConfigurer 
			sqlSessionFactory / basePackage
	-->
	<bean id="config" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.springmvc.mybaitsmodel"/>
		<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
	</bean>
	
	<!-- 4. 事务管理 : DataSourceTransactionManager -->
	<bean id="manager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="datasource"/>
	</bean>

	<!-- 5. 使用声明式事务 -->
	<tx:annotation-driven transaction-manager="manager" />

DAO：

public class UserDaoImpl implements UserDao {
	@Autowired 
	private SqlSession session;
	
	public SqlSession getSession() {
		return session;
	}

	public void setSession(SqlSession session) {
		System.out.println("runing......");
		this.session = session;
	}
.....
......后面执行的

想通过注入的方式直接获取session，然后直接调用其中的select等相应的方法，但是注入失败，没有在执行set方法，就大神解答！

围观下，事务处理配置这块，我也记不清了

不用配置呢 就是简单的注入什么的

使用 @Resource 引入注解 private SessionFactory mySessionFacotry; @Resource public void setMySessionFacotry(SessionFactory sessionFacotry) { this.mySessionFacotry = sessionFacotry; }

使用 @Resource 引入注解
private SessionFactory mySessionFacotry;
@Resource
public void setMySessionFacotry(SessionFactory sessionFacotry) {
this.mySessionFacotry = sessionFacotry;
}

报空指针错误 还是没注入进去，
引的包对吧：
import javax.annotation.Resource;

import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.springframework.beans.factory.annotation.Autowired;

import com.springmvc.mybaitsmodel.User;
import com.springmvc.mybatisUtil.MyBatisUtil;

有没有开启注解呢？ <!-- 开启注解 --> <context:annotation-config />
