解决方案

检查如下示例代码： 

 try (Meta meta1 = new Meta(null, new HashMap<>())){


}

new HashMap() 需要调整如下所示：

try (Meta meta1 = new Meta(null, BaseContextHandler.getMeta().getContext())){
            
}

为什么需要自己new Meta()

场景1 ： 服务是异步的情况，不是通过页面的API接口，以及启动事件触发！

平台提供了执行异步服务

示例代码如下所示：

  @MethodService(description = "发送消息")
  public void sendMsg(RecordSet rs){
      rs.callAsync("openWebSocket", 9999 );
  }
  
  @MethodService(description = "打开websocket端口")
  public void openWebSocket(int port){
      
  }

场景2： 消费事件执行服务的情况！

异步服务并不是通过引擎触发，提供如下代码所示:

BaseContextHandler.getMeta().getContext() 需要把同步的数据传递给新创建的Meta类。 如果实在没有，可以通过查库获取token内容。



try (Meta meta1 = new Meta(null, BaseContextHandler.getMeta().getContext())){
            
}
