使用的主类： @SpringBootApplication 公共类WebsocketPhynartApplication {
public static void main(String[] args) {
SpringApplication.run(WebsocketPhynartApplication.class, args);
}
}
当我碰到任何方法端点时，长宽比类不会显示“ Advice”，这实际上是我对“长宽比面向编程”的新手，有人可以帮助我吗？让我知道我还需要在项目中添加什么，我有什么遗漏吗？而且，如果我使用@Before代替PointCut，那么它会给我类似“ pointcut格式不正确”的错误
答案 0 :(得分：0)
@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内容
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");
}
}
由于您使用的是Spring Boot，所以我认为您不需要用@Configuration来注释@EnableAspectJAutoProxy类，但是在基于Spring框架的应用程序中，这是必需的。
