Question

尝试使用aop。

没有解决方法。

有人可以告诉我如何解决吗？

非常感谢！

线程“ main”中的异常java.lang.ClassCastException：AOP.ACimpl $$ EnhancerBySpringCGLIB $$ 144f4fe8无法转换为proxy.AC 在AOP.mym.main（mym.java:12）

 AC.class：

 package AOP;

 public interface AC {
    public  int add(int a, int b);
    public  int sub(int a, int b);

 }

ACimpl.class

ACimpl.class
import org.springframework.stereotype.Component;

@Component("ac")
public class ACimpl implements AC {
 @Override
 public int add(int a, int b) {

     System.out.println("add");

    return 0;
 }

@Override
 public int sub(int a, int b) {

     System.out.println("sub");

     return 0;
 }

}

LoginAspect.class

package AOP;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.springframework.stereotype.Component;

@Component
@Aspect
public class LoginAspect {

 @Before(value = "execution(public int AOP.AC.add(int,int))")
 public void befor(){
     System.out.println("run before method");
 }

}

main（）：

package AOP;

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

 public class mym {

 public static void main(String[]args){
     ApplicationContext ioc = new 
      ClassPathXmlApplicationContext("AOP/Aop.xml");

     AC ac = (AC) ioc.getBean("ac");
     ac.add(1,2);
     ac.sub(1,2);


  }

}

ExAOP.ACimpl $$ EnhancerBySpringCGLIB $ 144f4fe8无法转换为AOP.mym.main（mym.java:12）上的proxy.AC
