这是 JPush REST API 的 Java 版本封装开发包，是由极光推送官方提供的，一般支持最新的 API 功能。
对应的 REST API 文档：http://docs.jpush.cn/display/dev/REST+API
本开发包 Javadoc：API Docs
版本更新：Release页面。下载更新请到这里。
将下边的依赖条件放到你项目的 maven pom.xml 文件里。
<dependency> <groupId>cn.jpush.api</groupId> <artifactId>jpush-client</artifactId> <version>3.2.3</version> </dependency> 请到 Release页面下载相应版本的发布包。
其中 slf4j 可以与 logback, log4j, commons-logging 等日志框架一起工作，可根据你的需要配置使用。
如果使用 Maven 构建项目，则需要在你的项目 pom.xml 里增加：
<dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.2.4</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.5</version> </dependency> <!-- For log4j --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.5</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</version> </dependency> 如果不使用 Maven 构建项目，则项目 libs/ 目录下有依赖的 jar 可复制到你的项目里去。
可以用 Eclipse 类 IDE 导出 jar 包。建议直接使用 maven，执行命令：
maven package 在项目目录下执行命令：
mvn test 以下片断来自项目代码里的文件：example / cn.jpush.api.examples.PushExample
JPushClient jpushClient = new JPushClient(masterSecret, appKey, 3); // For push, all you need do is to build PushPayload object. PushPayload payload = buildPushObject_all_all_alert(); try{PushResult result = jpushClient.sendPush(payload); LOG.info("Got result - " + result)} catch (APIConnectionException e){// Connection error, should retry later LOG.error("Connection error, should retry later", e)} catch (APIRequestException e){// Should review the error, and fix the request LOG.error("Should review the error, and fix the request", e); LOG.info("HTTP Status: " + e.getStatus()); LOG.info("Error Code: " + e.getErrorCode()); LOG.info("Error Message: " + e.getErrorMessage())} 进行推送的关键在于构建一个 PushPayload 对象。以下示例一般的构建对象的用法。
- 快捷地构建推送对象：所有平台，所有设备，内容为 ALERT 的通知。
public static PushPayload buildPushObject_all_all_alert(){return PushPayload.alertAll(ALERT)} - 构建推送对象：所有平台，推送目标是别名为 "alias1"，通知内容为 ALERT。
public static PushPayload buildPushObject_all_alias_alert(){return PushPayload.newBuilder() .setPlatform(Platform.all()) .setAudience(Audience.alias("alias1")) .setNotification(Notification.alert(ALERT)) .build()} - 构建推送对象：平台是 Android，目标是 tag 为 "tag1" 的设备，内容是 Android 通知 ALERT，并且标题为 TITLE。
public static PushPayload buildPushObject_android_tag_alertWithTitle(){return PushPayload.newBuilder() .setPlatform(Platform.android()) .setAudience(Audience.tag("tag1")) .setNotification(Notification.android(ALERT, TITLE, null)) .build()} - 构建推送对象：平台是 iOS，推送目标是 "tag1", "tag_all" 的并集，推送内容同时包括通知与消息 - 通知信息是 ALERT，角标数字为 5，通知声音为 "happy"，并且附加字段 from = "JPush"；消息内容是 MSG_CONTENT。通知是 APNs 推送通道的，消息是 JPush 应用内消息通道的。APNs 的推送环境是“生产”（如果不显式设置的话，Library 会默认指定为开发）
public static PushPayload buildPushObject_ios_tagAnd_alertWithExtrasAndMessage(){return PushPayload.newBuilder() .setPlatform(Platform.ios()) .setAudience(Audience.tag_and("tag1", "tag_all")) .setNotification(Notification.newBuilder() .addPlatformNotification(IosNotification.newBuilder() .setAlert(ALERT) .setBadge(5) .setSound("happy") .addExtra("from", "JPush") .build()) .build()) .setMessage(Message.content(MSG_CONTENT)) .setOptions(Options.newBuilder() .setApnsProduction(true) .build()) .build()} - 构建推送对象：平台是 Andorid 与 iOS，推送目标是 （"tag1" 与 "tag2" 的交集）并（"alias1" 与 "alias2" 的交集），推送内容是 - 内容为 MSG_CONTENT 的消息，并且附加字段 from = JPush。
public static PushPayload buildPushObject_ios_audienceMore_messageWithExtras(){return PushPayload.newBuilder() .setPlatform(Platform.android_ios()) .setAudience(Audience.newBuilder() .addAudienceTarget(AudienceTarget.tag("tag1", "tag2")) .addAudienceTarget(AudienceTarget.alias("alias1", "alias2")) .build()) .setMessage(Message.newBuilder() .setMsgContent(MSG_CONTENT) .addExtra("from", "JPush") .build()) .build()} 以下片断来自项目代码里的文件：example / cn.jpush.api.examples.ReportsExample
