相关注解

1、@Aspect 放在类上面，把该类作为一个切面

2、@Pointcut 放在方法上面，定义一个可被别的方法引用的切入点表达式

3、@Before 放在方法上面，前置通知方法执行前执行

4、@After 放在方法上面后置最终通知方法最后执行

5、@AfterReturning 放在方法上面后置返回通知方法执行完执行

6、@AfterThrowing 放在方法上面后置异常通知方法异常时执行

7、@Around 放在方法上面环绕通知

---------------------示例代码---------------------

在pom.xml中配置

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency>

HttpAspect类代码
