java - 必须在 上定义 'pointcut' 或 'pointcut-ref' 之一

Question

这是方面类

public class TransactionAspect {

    public void beforeAnything() throws IOException{
        System.out.println("In the aspect");    
    }   

    public void beforeWithdrawalTransaction() throws IOException{
        System.out.println("In the aspect");
    }

    public void beforeDepositTransaction() throws IOException{
        System.out.println("In the aspect");
    }

    public void beforeBalance() throws IOException{
        System.out.println("In the aspect");
    }
}

这是我的方面的 xml 配置文件，我尝试了不同的方法，但仍然不起作用

<?xml version="1.0" encoding="UTF-8"?>
<beans>
    <aop:aspectj-autoproxy></aop:aspectj-autoproxy>

    <aop:config>

        <aop:pointcut id="forAnything" expression="execution(* com.pack.service.*.*(..))"  />
        <aop:advisor advice-ref="myAspectBean" pointcut="forAnything" id="interceptor" ></aop:advisor>

        <aop:aspect id="myAspect" ref="myAspectBean">

            <aop:before  method="beforeWithdrawalTransaction"  />
            <aop:before  method="beforeDepositTransaction" />
            <aop:before method="beforeBalance"/>

        </aop:aspect>
    </aop:config>       

    <bean id="myAspectBean" class="com.pack.aspect.TransactionAspect"/>
</beans>

当我尝试加载应用程序时，出现此错误:

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Must define one of 'pointcut' or 'pointcut-ref' on <advisor> tag.
Offending resource: class path resource [Spring.xml]
Aspect: id='myAspect'
    -> Advice (before)

我建议您将属性 pointcut-ref ="pointcut_id"添加到标签
