使用极光推送服务向App发送消息
为了实现将数据推送到App端，本文介绍如何基于极光推送（JPush）完成相关功能。以下是所需依赖和工具类代码的整理。
在
pom.xml 中添加以下依赖：<dependency>
<groupId>cn.jpush.api</groupId>
<artifactId>jpush-client</artifactId>
<version>3.3.0</version>
</dependency>
<dependency>
<groupId>cn.jpush.api</groupId>
<artifactId>jiguang-common</artifactId>
<version>1.0.8</version>
</dependency>以下是工具类代码示例：
import java.util.Map;
import cn.jiguang.common.resp.APIConnectionException;
