Spring AOP方法内部调用不生效的解决方案

public interface ISon {
    void A();
    void B();
}

@Service
public class Son implements ISon {
    @Override
    public void A() {
        System.out.println("method A");
    }
    @Override
    public void B() {
        System.out.println("method B");
        A();
    }
}

@Aspect
@Component
public class AspectDemo {

    @Pointcut(value = "execution(* com.example.transactiondemo.aop.ISon.A(..))")
    public void pointCut(){
    }

    @Before("pointCut()")
    public void before(JoinPoint joinPoint){
        System.out.println("before ");
    }

    @After("pointCut()")
    public void after(){
        System.out.println("after ");
    }

}

@Autowired
private ISon iSon;

@Test
public void test11(){
    iSon.A();
    System.out.println("-----------");
    iSon.B();
}

@EnableAspectJAutoProxy(exposeProxy = true,proxyTargetClass = true)

    @Override
    public void B() {
        System.out.println("method B");
        ((Son) AopContext.currentProxy()).A();
    }

@Autowired
private ApplicationContext applicationContext;

((Son) applicationContext.getBean(Son.class)).A();
