建议使用JPush 服务端SDK的人都先看下接口文档，了解推送api，具体链接：JPush v3 推送api文档
本人下载的是JPush Java 3.2.9版本的SDK源码（下载链接：JPush Java SDK 源码），在原PushExample类里面稍微改了下buildPushObject_all_all_alert方法，具体看代码：
public static void main(String[] args) {
testSendPush();
}
public static void testSendPush() {
JPushClient jpushClient = new JPushClient(masterSecret, appKey, 3);
PushPayload payload = buildPushObject_all_all_alert();
try {
PushResult result = jpushClient.sendPush(payload);
LOG.info("Got result - " + result);
} catch (APIConnectionException e) {
LOG.error("Connection error. Should retry later. ", e);
} catch (APIRequestException e) {
LOG.error("Error response from JPush server. Should review and fix it. ", e);
LOG.info("HTTP Status: " + e.getStatus());
LOG.info("Error Code: " + e.getErrorCode());
LOG.info("Error Message: " + e.getErrorMessage());
LOG.info("Msg ID: " + e.getMsgId());
}
}
public static PushPayload buildPushObject_all_all_alert() {
LOG.info("----------buildPushObject_all_all_alert");
IosAlert iosAlert = IosAlert.newBuilder().setTitleAndBody("title", "alert body").build();//创建一个IosAlert对象，可指定APNs的alert、title等字段
return PushPayload.newBuilder()
.setPlatform(Platform.all())//指定要推送的平台，all代表当前应用配置了的所有平台，也可以传android等具体平台
.setAudience(Audience.all())//指定推送的接收对象，all代表所有人，也可以指定已经设置成功的tag或alias或该应应用客户端调用接口获取到的registration id
.setNotification(Notification.newBuilder()//jpush的通知，android的由jpush直接下发，iOS的由apns服务器下发，Winphone的由mpns下发
.addPlatformNotification(AndroidNotification.newBuilder()//指定当前推送的android通知
.setAlert("android notification alert")
.setTitle("android notification title")
.setBuilderId(1)//设置Android 通知样式，需要客户端先定义、设置了该样式才有效
.addExtra("extras key", "extras value")//此字段为透传字段，不会显示在通知栏。用户可以通过此字段来做一些定制需求，如特定的key传要指定跳转的页面（value）
.build())
.addPlatformNotification(IosNotification.newBuilder()//指定当前推送的iOS通知
.setAlert(iosAlert)//传一个IosAlert对象，指定apns title、title、subtitle等
//.setAlert("ios notification alert")//直接传alert
.incrBadge(1)//此项是指定此推送的badge自动加1。如果想直接传具体值，可把incrBadge换成setBadge。
.setSound("sound.caf")//此字段的值default表示系统默认声音；传sound.caf表示此推送以项目里面打包的sound.caf声音来提醒，如果系统没有此音频则以系统默认声音提醒；此字段如果传空字符串，iOS9及以上的系统是无声音提醒，以下的系统是默认声音
.addExtra("iOS 的extras1", "JPush111")//此字段为透传字段，不会显示在通知栏。用户可以通过此字段来做一些定制需求，如特定的key传要指定跳转的页面（value）
.setContentAvailable(true)//此项说明此推送是一个background推送，想了解background看：http://docs.jpush.io/client/ios_tutorials/#ios-7-background-remote-notification
.build())
.addPlatformNotification(WinphoneNotification.newBuilder()
.setAlert("WinPhone notification alert")
.setOpenPage("xxxx.cs")//指定点击打开的页面（类）,具体后缀忘记，错了请指正
.addExtra("WinPhone extras key", "WinPhone extras value")
.build())
.build())
.setMessage(Message.newBuilder()//Platform指定了哪些平台就会像指定平台中符合推送条件的设备进行推送。 jpush的自定义消息，sdk默认不做任何处理，不会有通知提示。建议看文档http://docs.jpush.io/guideline/faq/的 [通知与自定义消息有什么区别？]了解通知和自定义消息的区别
.setMsgContent("message content")
.setTitle("message titile")
.addExtra("message extras key", "message extras value")
.build())
.setOptions(Options.newBuilder()
.setApnsProduction(false)//此字段的值是用来指定本推送要推送的apns环境，false表示开发，true表示生产；对android和自定义消息无意义
.setSendno(1)//此字段是给开发者自己给推送编号，方便推送者分辨推送记录
.setTimeToLive(86400)//此字段的值是用来指定本推送的离线保存时长，如果不传此字段则默认保存一天，最多指定保留十天；
.build())
.build();
}
请求结果如下：

msg_id是jpush中此推送的唯一标识，如果对某推送有疑问可以向他们提供具体msg_id。
注：本人并不擅长写文档，此文仅给刚使用jpush 服务端sdk 开发者参考。如果写的不好，请谅解，提出改进建议。
