Question

当我练习时 Spring教程28 - 切入点和通配符表达式，我遇到以下问题：

Exception in thread"main"org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'triangle' defined in class path resource
[springPointcuts.xml]: Initialization of bean failed; nested exception is
java.lang.IllegalArgumentException: error at ::0 can't find referenced
pointcut allGetters

您将在下面看到我的代码我非常感谢你解决我的问题。

LoggingAspectPointcuts：

package org.koushik.javabrains.aspect;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class LoggingAspectPointcuts {

    @Before("allGetters()")
    public void LoggingAdvice(){
    System.out.println("Advice run.Get Method called");
    }

    @Before("allGetters()")
    public void secondAdvice() {
    System.out.println("Second Advice executed ");
    }

    @Pointcut("execution(* get*())")
    public void allGetters(){}


}

AopMainWildCardPointcuts：

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import org.koushik.javabrains.service.ShapeService;

public class AopMainWildCardPointcuts {

    public static void main(String[] args) {


        ApplicationContext ctx = new ClassPathXmlApplicationContext("springPointcuts.xml");

        ShapeService shapeService= (ShapeService) ctx.getBean("shapeService");
        System.out.println(shapeService.getCircle().getName());



    }

springPointcuts.xml：

Answer 1

我猜你可能正在使用1.5版本的aspectjrt和aspectjweaver jars.use任何1.6版本你都会得到它wworkin

Answer 2

替换....

<aop:aspectj-autoproxy/>

与......

<aop:aspectj-autoproxy>
     <aop:include name="loggingAspectPointcuts"/>
</aop:aspectj-autoproxy>

Answer 3

尝试使用正确版本的cglib.jar使用版本2.1_3或最新版本

asm-3.3.1
cglib-2.2.2
aspectjrt-1.6.11
aspectweaver-1.6.11.

确保使用上述罐子。

当我尝试使用切入点和通配符表达式创建Bean时，为什么会出现错误？
