Java 带有Spring引导服务器通知（）的FCM消息传递构造函数问题

我正在尝试使用Firebase SDK向基于令牌的设备发送推送通知。 我已经在Spring Boot中实现了服务器。我可以用下面的信息向我的设备发送信息 有效载荷

{
    "token":"eXn97K74SoavdyblW3-8cFQDgLFzVhLCIDugdvmofbIzSmwY4ty3MwuTdFQ48sIQU9QSdLKC1BWE6NeL8zYS.....",
    "notification":{
      "title":"Portugal vs. Denmark",
      "body":"great match!"
    },
    "data" : {
      "body" : "Mario",
      "title" : "PortugalVSDenmark",
      "click_action":"test"
    }
  }

但若我将click_操作字段添加到通知构造函数中，那个么我在服务器中的代码只会这样说 允许使用标题和正文字段。然而令人惊讶的是，在Android Studio中，its显示了一个名为getNotification（）点getClickAction（）的方法，所以我这里的问题是如何使这个click\u action属性适合我的服务器逻辑。任何建议都会有帮助

here is my Service class in Spring boot

当您提出请求时，只需将其放入数据：

"data": {
        "key1": "Value 1",
        "key2": "Value 2",
        "key3": "Value 3",
        "key4": "Value 4",
        "click_action": "FLUTTER_NOTIFICATION_CLICK"
    }

我想发送这样的东西。{“token”：“eXn97K74SoavdyblW3 awo:APA91BHPPVGNIA8CFQDGLFZVHLCIDUGDVMOYHZYD68ZNHAZAK4L8K9MKHDK4QHNZMRFIBUNQDSDxeikdKJpZIUSUMIUBILFBIZMWY4WUTDFQ48SIQU9QSDLKC1BWE6NEL8ZYS”，“通知”：“标题”：“葡萄牙对丹麦”，“正文”：“伟大的比赛！”，“点击动作”：“测试”}，“数据”：“正文”：“马里奥”，“title”：“PortugalVSDenmark”，“click_action”：“test”}}您找到解决方案了吗？
