mqtt - Seedstack - 添加用户和密码的 MQTT 附加组件问题

Question

我尝试连接到 MQTT 服务器，但在添加密码时遇到了一些问题：

配置文件是：

mqtt:
  clients:
    client-ptl-mqtt: 
      serverUri: tcp://rdabeg01.inetpsa.com:1883
      clientId: LOCAL_PTL_SIMUL_MQTT
      connection:
        userName: xxxxxx
        password: xxxxxxx
      reconnectionMode: ALWAYS

当我尝试启动应用程序时的错误是：

org.seedstack.cofig.internal.ConfigurationException: [CONFIGURATION] 非法转换

说明 ----------- 无法转换为 char(char.java:1): 'xxxxxxx'。

SeedStack MQTT 插件依赖于 Paho，它有一个用于客户端连接MqttConnectOptions的配置类。密码字段需要一个字符数组，插件不会改变它。您的 YAML 进行了相应修改：

mqtt:
  clients:
    client-ptl-mqtt: 
      serverUri: tcp://rdabeg01.inetpsa.com:1883
      clientId: LOCAL_PTL_SIMUL_MQTT
      connection:
        userName: xxxxxx
        password: [ 'p', 'a', 's', 's', 'w', 'o', 'r', 'd' ]
      reconnectionMode: ALWAYS
