Spring AOP 实现不适用于我使用@Aspect 的项目

Question

看点class:

    package com.phynart.cloud.aop;

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

    @Aspect
    @Component
    public class MyAspect {

        @Pointcut("execution(com.phynart.cloud.*.*(..))")
        public void before() {      
            // Advice
            System.out.print("Advice");
        }   
    }

使用的主要class： @SpringBootApplication public class WebsocketPhynartApplication {

public static void main(String[] args) {
    SpringApplication.run(WebsocketPhynartApplication.class, args);
}

}

当我点击任何方法端点时，方面 class 不会打印 "Advice" 实际上，我是面向方面编程的新手，有人可以帮助我吗？让我知道我还需要在我的项目中添加什么，我是否遗漏了什么？此外，如果我使用 @Before 而不是 PointCut 那么它会给我错误 "pointcut is not well-formed"

Answer 1

@Before 或 @After 应该可以完成这项工作。将您的方面组件更改为类似的东西

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

@Aspect
@Component
public class MyAspect {

    @Before("execution(* com.phynart.cloud.*.*(..))")
    public void before() {
        System.out.println("Advice");
    }

}

我认为你不需要用 @EnableAspectJAutoProxy 注释你的 @Configuration class 因为你使用的是 Spring 引导，但是在 Spring 基于框架的应用程序，那将是必要的。
