spring配置error2 AOP事务配置缺少包

写贴上在spring 配置文件applicationContext.xml的事务配置

 <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">        <property name="dataSource" ref="dataSource" />        <property name="configLocation" value="classpath:hibernate.cfg.xml" /> <!-- 加载hibernate配置文件 -->    </bean>    <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">        <property name="sessionFactory" ref="sessionFactory" />    </bean>    <bean id="categoryService" class="com.eshop.service.impl.CategoryServiceImpl">        <property name="sessionFactory" ref="sessionFactory" />    </bean>    <tx:advice id="advice1" transaction-manager="transactionManager">        <tx:attributes>            <tx:method name="save*" propagation="REQUIRED"/>            <tx:method name="update*" propagation="REQUIRED"/>            <tx:method name="delete*" propagation="REQUIRED"/>            <tx:method name="*" propagation="SUPPORTS"/>        </tx:attributes>    </tx:advice>    <aop:config>        <!-- 配置哪些包的类要切入事务 -->        <aop:pointcut id="pointcut1" expression="execution(* com.eshop.service.impl.*.*(..))" />        <aop:advisor advice-ref="advice1" pointcut-ref="pointcut1"/><!-- 连接了上面的advice和上面的pointcut -->    </aop:config>

在测试类中运行后出现error

@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = "classpath:applicationContext.xml")public class test {    @Resource    private Date date;    @Test    public void springIOC(){        System.out.println(date);    }    @Test    public void hibernate() {        CategoryService categoryService = new CategoryServiceImpl();        Category category = new Category("男士休闲kk", true);        categoryService.save(category);

}

java.lang.IllegalStateException: Failed to load ApplicationContext

测试的错误信息较长 总结 出错信息如下

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.event.internalEventListenerProcessor': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.support.DefaultBeanFactoryPointcutAdvisor#0': Cannot resolve reference to bean 'pointcut1' while setting bean property 'pointcut'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pointcut1': Failed to introspect bean class [org.springframework.aop.aspectj.AspectJExpressionPointcut] for lookup method metadata: could not find class that it depends on; nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException

看到最后一句话 could not find class that it depends on;nested exeception is java**

原因是缺少依赖包aspectjweaver.jar 一般还要导入aopalliance.jar aspectjrt.jar

我所用的时intellij idea 创建工程时的环境是spring 4.3.12  此时spring对于aop编程提供只有2个包

为什么spring实现了aop还需要导入依赖包？

:spring AOP就是用aspectj来实现的,是依赖关系!AspectJ是动态代理的一种实现!而spring默认使用的就是AspectJ来实现的动态代理,spring自己的AOP就是使用AspectJ来实现的,而aspectjweaver.jar这个包是spring集成AspectJ LTW织入器所需包

导入提到的包 error解决
