使用Spring引導和aspectj創建庫

Question

我使用spring引導和aspectj創建了一個庫。

我已經創建了一個配置類

@Configuration 
@EnableAspectJAutoProxy 
@ComponentScan(basePackages="com.x.y") 
public class LoggerConfig { 
} 

一類用於註解

@Target(ElementType.METHOD) 
@Retention(RetentionPolicy.RUNTIME) 
public @interface EnableHttpLogging { 
} 

和一類用於方面

@Aspect 
@Component 
public class LoggerAspect { 

@Around("execution(* *(..)) && @annotation(EnableHttpLogging)") 
    public Object handleController(final ProceedingJoinPoint proceedingJoinPoint) 
      throws Throwable { 

     LOG.info("controller....before "); 
     return proceedingJoinPoint.proceed(); 

    } 

} 

中導入一個類之後發生錯誤配置「@Import（LoggerConfig.class）」到我的應用程序，並試圖運行它，我有fo llowing錯誤：

您需要修改的handleController方法簽名和內部@annotation提供的參數。下面顯示的示例應該可以工作。

@Aspect 
@Component 
@Slf4j 
public class LoggerAspect { 

    @Around("execution(* *(..)) && @annotation(annotation)") 
    public Object handleController(
      final ProceedingJoinPoint proceedingJoinPoint, 
      EnableHttpLogging annotation) 
      throws Throwable { 

     LOG.info("controller....before "); 
     return proceedingJoinPoint.proceed(); 

    } 

}
