spring integration-mqtt型转换器问题

尝试从web运行示例spring-integration mqtt项目。 我在根上下文中导入了mqtt-context。部署战争后，我正在运行RunMqtt.java文件。但是得到以下问题。如果在独立模式下运行，则同一文件不会产生任何问题。

示例spring-integration mqtt项目

哪个样本？

请显示您的配置。

修改：

看起来Spring无法确定要使用哪个构造函数。

尝试添加

<bean id="clientFactory" class="org.springframework.integration.mqtt.core.DefaultMqttPahoClientFactory" />

并将client-factory="clientFactory"添加到邮件驱动的适配器。
