添加了Aspectj坐标依赖，但还是报错，使用注解方式实现AOP可以运行，但使用xml就无法生成Bean

Question

下面是报错内容

下面是的我代码：

package com.lkc.Aspect;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.stereotype.Component;
@Component
public class LogCut {
    public void cut(){

    }
    public void before(){
        System.out.println("前置通知...");
    }

    public void afterReturn(){
        System.out.println("返回通知...");
    }

    public void after(){
        System.out.println("最终通知...");
    }
    public void afterThrow(){
        System.out.println("异常通知...");
    }

    public Object around(ProceedingJoinPoint pjp){
        System.out.println("环绕通知的前置通知。。。");
        Object o=null;
        try {
            o=pjp.proceed();
            System.out.println("环绕通知的返回通知。。。");
        } catch (Throwable e) {
            e.printStackTrace();
            System.out.println("环绕通知的异常！");
        }
        System.out.println("环绕通知的最终通知。。。");
        return o;
    }

        UserService userService= (UserService) ac.getBean("userService");
        userService.show();
    }
}

下面是我引入的坐标依赖：

<dependency>
      <groupId>org.aspectj</groupId>
      <artifactId>aspectjweaver</artifactId>
      <version>1.7.4</version>
    </dependency>

Answer 1

Caused by: java.lang.IllegalArgumentException: Pointcut is not well-formed: expecting 'identifier' at character position 0
* com.lkc.service.*.*(..)

配置切点的地方报错了。
expression改一下，值在execution中。

 expression="execution(* com.lkc.service.*.*(..) "/>
