Answer 1

是否指定自定义冲突解决程序：

<mvc:annotation-driven>
    <mvc:argument-resolvers>
        <ref bean="notificationResolver" />
    </mvc:argument-resolvers>
</mvc:annotation-driven>

<aws-messaging:notification-argument-resolver id="notificationResolver" />

另外，我看不到控制器映射，但在教程中有一条语句：

目前，无法在方法级别上定义映射URL，因此RequestMapping必须在类型级别上完成，并且必须包含endpoint的完整路径。
