我正在尝试运行示例MQTT-SPring集成项目。我如何修改一些配置细节以从属性文件获取。并尝试从
runMQTT.java
文件连接到MessageBroker

代码片段如下所示

</beans>
在这种情况下，mqtt或sftp或resthttp属性加载失败。请帮助解决

属性文件 mqtt.properties
mqttbrokerrurl=tcp://172.18.128.150:1883根据StackTrace，您的属性占位符没有解析，这只是因为您的属性文件没有

即使你说它是：

属性（mqttbrokerurl、serveruri）是从根上下文加载的

我在你的代码中没有看到这些东西：

  • 仅显示
    MQTT Context.xml

  • 您的
    RunMqtt
    仅启动该上下文：

    new ClassPathXmlApplicationContext("/META-INF/spring/integration/mqtt/mqtt-context.xml");
    • 因此，请修复这些问题，并返回给我们进一步的进展。

    请参阅。在web应用程序中运行时，类路径与web上下文相关。

    根上下文如下所示：无问题！但正如我所说：您不需要从
    RunMqtt
    加载它，只需
    mqtt context.xml
    ，您应该确保
    classpath:/mqtt.properties
    是正确的路径，并且您的属性文件位于根目录中。否则，您应该在
    .M-M-M中为上下文指定完整路径。这不适合你吗<代码>类路径：/mqtt.properties。我的意思是没有slashPlease，打开
    org.springframewrok
    的
    DEBUG
    ，查看日志中
    propertysourcesplaceconfigurer
    对文件的说明。
