在xml文件中配置spring aop配置时报错

问题遇到的现象和发生背景

在xml文件中配置spring aop配置时在expression="execution(com.UserDaoImpl.(..))"上报错

用代码块功能插入代码，请勿粘贴截图

package com

interface UserDao {
    fun insert()
    fun delete()
    fun update()
    fun select()
}

package com

class UserDaoImpl {
    fun insert(){
        println("Inserting")
    }
    fun delete(){
        println("Deleting")
    }
    fun update(){
        println("Updating")
    }
    fun select(){
        println("selecting")
    }
}

package com

import org.aspectj.lang.JoinPoint
import org.aspectj.lang.ProceedingJoinPoint

class XmlAdvice {
    fun before(joinPoint: JoinPoint) {
        print("前置")
        print("目标类" + joinPoint.target)
        println(",植入的增强项" + joinPoint.signature.name)
    }
    fun afterReturning(joinPoint: JoinPoint) {
        print("返回")
        println("被植入"+joinPoint.signature.name)
    }
    @Throws(Throwable::class)
    fun around(point: ProceedingJoinPoint): Any {
        println()
        val objcet = point.proceed()
        println("环绕后")
        return objcet
    }
    fun afterException(){
        println("异常")

    }
    fun after(joinPoint: JoinPoint) {
        println("后置applicationContext.xml")
    }

}

    <aop:config>
        <aop:pointcut id="pointcut" expression="execution(*com.UserDaoImpl.*(..))"/>

        <aop:aspect ref="xmladvice">

        aop:aspect>

   aop:config>

beans>

运行结果及报错内容

com.UserDaoImpl.(..)的点会报错

我想要达到的结果

如何能解决报错？

给一份pointCut表达式参考：https://blog.csdn.net/weixin_43793874/article/details/124753521
