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>3.2.6</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

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();
