自定义注解+AOP实现面向切面编程

一、自定义注解

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface AroundInterceptor {
    String value() default "";
}

二、切面方法

@RestController
public class  MyController(){
	@AroundInterceptor
	public void mythod(){
		//TODO
	}
}

三、业务处理

@Component
@Aspect
public  class MyAspect（）{
  	
  	@Pointcut("@annotation(com.mollen.demo.interceptors.AroundInterceptor )")
    public void sendMsgAfterReturnAdvice() {
        // TODO
    }
	@Around("sendMsgAfterReturnAdvice()")
    public void aspectService(JoinPoint jp){
    
		MethodSignature signature = (MethodSignature) jp.getSignature();
        AroundInterceptor annotation = signature.getMethod().getAnnotation(AroundInterceptor .class);
        // 注解参数值
        String value = annotation.value();
        //方法参数值
        Object[] args = jp.getArgs();
		
		//TODO

}
