使用Java-PNS向iPhone发送推送通知时发生错误？

Question

我正在使用javaPNS_2.2.jar文件向iPhone设备发送推送通知消息。

我的代码是：

PushNotificationPayload payload = PushNotificationPayload.complex(); 

/* Customize the payload */ 
payload.addAlert("Hello World!"); 
payload.addCustomDictionary("mykey1", "My Value 1"); 
payload.addCustomDictionary("mykey2", 2); 

/* Push your custom payload */ 
String keystore = "C:/1.0Eywa_Baba/PushNotificationKey.p12"; 
String password = "Eywa@12"; 
boolean production = false; 
String devices = "C81DD339-F5C1-529F-BEC4-6C8622BA0BFD"; 
List<PushedNotification> notifications = Push.payload(payload, 
                 keystore, 
                 password, 
                 production, 
                 devices); 

不过，我得到的错误：

log4j:WARN No appenders could be found for logger (javapns.notification.Payload). 
log4j:WARN Please initialize the log4j system properly.

是什么原因造成这个异常？

Answer 1

将bouncycastle库包含在您的项目中。

在项目的classpath中包含bcprov-jdk15-140 jar。
