SSM框架 spring-context 配置自动扫描 不能注入service和dao

Question

Answer 1

<context:component-scan base-package="com.jsu.service,com.jsu.util"/>
    <!--配置session工厂-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="mapperLocations" value="classpath:mybatis/*Mapper.xml"/>
    <property name="typeAliasesPackage" value="com.jsu.mapper"/>
</bean>

<!--扫描mapper代理对象-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <!--设置扫描mapper的包-->
    <property name="basePackage" value="com.jsu.mapper"/>
    <!-- mapper接口需要用到sqlSessionFactory 如果上下文环境只有一个数据源 则不需要配置 -->
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
</bean>
    <!--配置通知-->
<tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
        <tx:method name="get*" read-only="true"/>
        <tx:method name="select*" read-only="true"/>
        <tx:method name="insert*" propagation="REQUIRED"/>
        <tx:method name="update×" propagation="REQUIRED"/>
        <tx:method name="delete*" propagation="REQUIRED"/>
    </tx:attributes>
</tx:advice>

<!--配置切面-->
<aop:config>
    <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.jsu.service.impl.*.*(..))"/>
</aop:config>
<!--开启注解-->
<tx:annotation-driven transaction-manager="txManager"/>



    以上是我常用的配置的方式
