springAOP拦截并打印controller层请求日志---注解方式实现

        String description = "";
        for (Method method : methods) {
            if(method.getName().equals(methodName)) {

                if(clazzs.length == arguments.length) {
                    description = method.getAnnotation(SystemLog.class).description();

                }
            }
        }
        return description;
    }
}

注解：

/**
 * System log annotation for controller or service
 * Created by wenqiangxia on 9:10 2017/11/2
 */
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemLog {

    String description() default "";
}

注解加在controller层方法上即可
