上一节已经学习了CLI命令行来控制JBOSS，如果想在程序中以编码方式来控制JBOSS，可以参考下面的代码，实际上在前面的文章，用代码控制Jboss上的DataSource，已经有所接触了，API与CLI是完全等价的，一个是人工敲指令，一个是代码控制，二者最终的效果一致。

除了native managent API外，jboss还提供了一套基于http的REST风格API，即9990端口对应的API，有兴趣的可以参考下面的文章
https://docs.jboss.org/author/display/AS71/The+HTTP+management+API
https://docs.jboss.org/author/display/AS71/The+native+management+API
GitHub有一个开源项目，从手机上管理jboss，就是基于http的这一套API实现的，技术上讲 ，利用这二套API，完全可以自己定制一套Jboss管理控制台(不管是c/s还是b/s)
最后送点福利，GitHub上的开源项目jboss-controller-operation-executor，我在原来的基础上，增加了几个domain模式下的控制方法，包括 停止/启用某一台服务器、获取服务器状态、停止/启用某个ServerGroup下所有Server，并增加了单元测试的示例代码，并将pom依赖项，升级到7.5，以兼容JBOSS EAP 6.4
