Question

我使用spring boot和aspectj创建了一个库。

我已经创建了一个配置类

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

注释的类

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

和方面的类

@Aspect
@Component
public class LoggerAspect {

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

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

    }

}

将类配置“@Import（LoggerConfig.class）”导入我的应用程序并尝试运行它后发生错误，我有以下错误：

您需要修改handleController的方法签名和@annotation中提供的参数。下面显示的示例应该有效。

@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();

    }

}

使用Spring引导和aspectj创建库
