Aop切面到具体方法失效

做了一个aop切面小demo，但是突然发现aop失灵了

以下是小demo的源码

网上查了一下原因，基本就是：不是通过代理对象调用的，而是本身调用的，而aop的切入是需要使用动态代理对象，但是咱们调用的是本身对象。

所以改正方法，就是通过代理对象调用一下方法就可以了

   this.serverTest(new HashMap()); 改成以下代码

 
   解决方案
   AopService aopService=SpringContextUtils.getBean(AopService.class);

  aopService.serverTest(new HashMap());
    这样就是属于通过代理对象调用了

    @Pointcut("execution(* com.example.demo.service.AopService.serverTest(..))")
    public void test(){}

    @AfterThrowing(pointcut = "test()",throwing = "exceptio")
    public void deEx(JoinPoint joinPoint , Exception exceptio){
        log.error("=============================执行切面");

    }
