タグ: spring aop, spring hibernate, spring transaction

Spring + Hibernate4の統合、およびトランザクションは、Spring AOPによって管理されます。例:

spring-hibernate.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/aop

    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

    <bean id="txManager"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="get** " read-only="true"/>
            <tx:method name="** "/>
        </tx:attributes>
    </tx:advice>

    <aop:config>
        <aop:pointcut id="userDaoPointCut"
            expression="execution(**  com.mkyong.users.service.** Dao.** (..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="userDaoPointCut"/>
    </aop:config>

</beans>

システムは `ClassNotFoundException:org.aspect.weaver …`を表示します。

解決策

これを解決するために、
spring-aspects`を宣言すると、
org.aspectj`ライブラリが自動的に取得されます。

pom.xml

    <properties>
        <spring.version>3.2.8.RELEASE</spring.version>
    </properties>

    <dependencies>
