javapns不报错却收不到推送，这是为何

下面进行自问自答环节，搞了一天终于在找到了问题的关键所在：
【估计卡住的人通常是和apns握手失败。这原因主要是java、.net和mac的ssl连接区别.
java需要把下载的文件再次转换才可以使用。】注意你用到的.p12并文件不是一开始从苹果官网下载过来的那个，而是要通过转换的，步骤如下：
（ps: socketClient.p12 是那个从苹果官网下载过来的，而最后使用的是apns_dev_key_for_java.p12）
1. openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem2. openssl pkcs12 -nocerts -out PushChatKey.pem -in socketClient.p123. openssl pkcs12 -export -in PushChatCert.pem -inkey PushChatKey.pem -certfile socketClient.certSigningRequest -name "apns_dev_key_for_java" -out apns_dev_key_for_java.p12
