java - 通过 JavaPNS 发送通知时发生异常

Question

通过 JavaPNS 发送推送通知时，发生异常并显示以下消息。

Exception in thread "JavaPNS grouped notification thread in LIST mode" java.lang.OutOfMemoryError: Java heap space

我猜原因是因为我尝试向太多用户发送通知1次。

public void send (List<Device> devices, Object keystore, String password, boolean production) {

       /* Prepare a simple payload to push */ 
        PushNotificationPayload payload = PushNotificationPayload.alert("Hello World!");


       /* Decide how many threads you want to create and use */ 
        int threads = 30;


       /* Start threads, wait for them, and get a list of all pushed notifications */ 
        List<PushedNotification> notifications = Push.payload(payload, keystore, password, production, threads, devices);


}

我将 73,889 个设备 token 添加到列表devices 中并收到了异常。

您认为我需要多次发送通知吗？有人知道向很多人发送通知吗？

谢谢!

Answer 1

我可以想出 2 个解决方案来解决您的问题:

1) 批量发送...比如 20k

或

2)增加堆内存大小

示例:java -Xms512m -Xmx512m

(进行搜索...)
