<h1 id="SPI定制化">SPI定制化</h1><h2 id="什么是SPI">1. 什么是SPI</h2><p>建议直接百度 <code>java spi</code>, 官方介绍: <a href="http://docs.oracle.com/javase/tutorial/sound/SPI-intro.html" target="_blank">http://docs.oracle.com/javase/tutorial/sound/SPI-intro.html</a></p><h2 id="mpush_使用SPI的目的">2. mpush 使用SPI的目的</h2><p>肯定是为了扩展性，在不想修改源码的情况下，去替换系统原有的实现，代价最小也最灵活。</p><h2 id="mpush目前支持的SPI列表">3. mpush目前支持的SPI列表</h2><p><strong>所有受支持的SPI都在<code>mpuhs-api</code>模块的<code>com.mpush.api.spi</code>包下面。</strong></p><ul><li><code>ServerEventListenerFactory</code> 监听Server 产生的相关事件
</li>
<li><code>BindValidatorFactory</code> 绑定用户身份是校验用户身份是否合法
</li>
<li><code>ClientClassifierFactory</code> 同一个用户多设备登录互踢策略，默认Android和ios会互踢
</li>
<li><code>PushHandlerFactory</code> 接收客户端发送到服务端的上行推送消息
</li>
<li><code>ExecutorFactory</code> 整个系统的线程池工厂，可以按自己的策略创建线程池
</li></ul>
<h2 id="开发流程">4. 开发流程</h2><ul><li>新建一个maven工程，并加入mpush-api模块的依赖
</li>
<li>实现要定制的接口和其对应的Factory
</li>
<li>在resources目录下创建META-INF.services目录
</li>
<li>创建名字为<code>com.mpush.api.spi.xxx.XXXFactory</code>的文件，即对应的接口名
</li>
<li>文件的内容为实现类的全名(packageName+className)
</li>
<li>通过mvn打成jar包，并把其放到mpush/lib目录
</li>
<li>重启mpush server 就会优先加载用户提供的实现来覆盖原有的默认实现
</li></ul>
