使用Javapns、Java和googleappengine的苹果推送通知服务 @RequestMapping（“/initSendPushNotification.html”） 公共字符串initSendPushNotification（）引发FileNotFoundException{ log.debug（“……启动initSendPushNotification方法…………”）； 字符串password=“Initial”； 布尔沙盒=真； 字符串[]设备={“cc287c9008c08a8d6cedb9ca22318d675c6b4bf20101244fa1964790c9585f48” “41F888FE5DC2AC37481D6E6F7FAC09A30AD408A016276504EAB20C5DB1E9BA”； 试一试{ 字符串certificate=“/Certificates.p12”； File keystore=新文件（getClass（）.getResource（certificate）.toURI（））； log.debug（“……密钥库…………”+密钥库）； List notifications=Push.alert（“你好，苹果，这是一条测试消息，名为Push！From:recorosoft”、密钥库、密码、沙盒、设备）； 对于（推送通知：通知）{ if（notification.issusccessful（））{ log.debug（……..成功！苹果接受了通知，并应提交该通知………..+通知）； } 否则{ 字符串invalidToken=notification.getDevice（）.getToken（）； log.debug（..success！在此处添加代码以从数据库中删除invalidToken……..+invalidToken）； } } log.debug（“……………End initSendPushNotification方法…………”）； 回复“你好”； }捕获（通信异常e）{ 日志错误（“……通信异常……”，e）； } 捕获（KeystoreException e）{ 日志错误（“……..KeystoreException………..”，e）； } 捕获（URISyntaxException e）{ 日志错误（……..URISyntaxException………..”，e）； } 回复“你好”； }

}

我已经创建了.p12证书，并且获得了64个字长的设备令牌。在这里，上面的应用程序运行正常，并从我的本地主机发送推送通知，但当我在谷歌云中部署它时，它不会发送推送通知，因为我使用谷歌应用程序引擎作为服务器。这里是谷歌云抛出的一个例外

@RequestMapping("/initSendPushNotification.html")
