spring integration-mqtt 类型转换器问题

Question

尝试从 web 运行示例 spring-integration mqtt 项目。 我已经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。但得到以下问题。如果在独立模式下运行，相同的文件不会出现任何问题。

spring-integration mqtt 项目示例

哪个样本？

请显示您的配置。

编辑：

看起来 Spring 无法确定使用哪个构造函数。

尝试添加

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

并将client-factory="clientFactory" 添加到消息驱动适配器。
