- 创建一个自定注解，接收一个传值type
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface EchoStatus {String type();
}
- 创建一个切面类，绑定一些切面方法，比如before，after…
@Aspect
@Component
@Slf4j
public class EchoStatusAspect {@Pointcut("@annotation(com.gbs.mgt.annotation.EchoStatus)")public void customPointcut() {}@Before("customPointcut()")public void beforeAdvice(JoinPoint joinPoint) {Object[] args = joinPoint.getArgs();System.out.println("Before method execution: " + joinPoint.getSignature().getName()+"入参："+ Arrays.asList(args));}@After(value = "customPointcut()")public void afterAdvice(JoinPoint joinPoint) {System.out.println("After method execution: " + joinPoint.getSignature().getName());}@AfterReturning(value = "customPointcut()", returning = "result")public void afterReturningAdvice(JoinPoint joinPoint, Object result) {System.out.println("After method execution: " + joinPoint.getSignature().getName()+"结果："+result);}
}
@EchoStatus (type = "无所谓")
public String index(){return "hello word";
}
