Java 极光推送分组推送

前提：
项目采用alias别名推送，极光推送按照别名推送，一次只能推1000条，因此，在数量>1000的情况下采用分组推送
jar包：极光官网提供的极光jar，除此之外还需要slf4j-api-1.7.5.jar与slf4j-log4j12-1.7.5.jar

1.分组

    /*** @throws APIRequestException* @throws APIConnectionException* @throws Exception*/private void pushMsgToUser(int type) throws APIConnectionException, APIRequestException, Exception {// 检索符合条件的别名List Devices = aliasService.selDevices(type);int size = Devices.size();List> pgrp = new ArrayList>();//超过999条分组推送，小与999条一次推送if (size > 998) {int n = 5;//假设分成5组int number=size/n;//每组的个数int remainder=size%n;//余数int offset=0;//偏移量for (int i=0 ; i < n ; i++ ){List pp = null;if (remainder > 0){pp=Devices.subList(i*number+offset,(i+1)*number+offset+1);remainder--;offset++;}else {pp=Devices.subList(i*number+offset, (i+1)*number+offset);}pgrp.add(pp);}for (List li : pgrp) {boolean result = JPushUtil.pushMsg(li, "有新信息，请注意查看。", "有新信息");if (!result) {System.out.println("推送消息失败");}}}else {boolean result = JPushUtil.pushMsg(Devices, "有新信息，请注意查看。", "有新信息");if (!result) {System.out.println("推送消息失败");}}}

2.调用推送方法

public class JPushUtil {//自己项目的appkey和secretprivate static final String APPKEY ="";private static final String SECRET = "";//极光推送测试环境private static final boolean APNS_PRODUCTION = false;/*** 推送消息给用户* @param alias 别名* @param alert 标题* @param msgContent 内容* @param setApnsProduction* @return* @throws APIConnectionException* @throws APIRequestException*/public static boolean pushMsg(List alias, String alert, String msgContent, String sound) throws APIConnectionException, APIRequestException {// 极光推送自定义参数变量Map extras = new HashMap();JPushClient jpushClient = new JPushClient(SECRET, APPKEY);PushPayload payload = PushPayload.newBuilder().setPlatform(Platform.android_ios()).setAudience(Audience.alias(alias)).setNotification(Notification.newBuilder().addPlatformNotification(IosNotification.newBuilder().setAlert(alert).incrBadge(1).setSound("happy.caf").addExtra("from", "JPush").build()).addPlatformNotification(AndroidNotification.newBuilder().setAlert(alert).setTitle(msgContent).build()) .build()).setMessage(Message.content(msgContent)).setOptions(Options.newBuilder().setApnsProduction(APNS_PRODUCTION).build()).build();PushResult pushResult = jpushClient.sendPush(payload);return pushResult.isResultOK();}}
