1、准备工作
阿里短信平台：
https://www.aliyun.com/product/sms?utm_content=se_1006519387
阿里云的账号我已经有了，也通过了实名认证，接下来的开通短信服务、申请签名、申请短信模板也都不难，关键是得等后台审核，挺耽误时间的
我的模板内容：
告警区域：${area}，告警时间：${time}，告警信息：${msg}。
快速学习界面：
https://dysms.console.aliyun.com/dysms.htm?spm=a2c4g.11186623.2.12.67466d880lhyXx#/quickStart
还提供了sdk和demo的下载
2、集成到项目
导入两个需要依赖的jar
工程依赖了2个jar包(存放在工程的libs目录下)
* 1:aliyun-java-sdk-core.jar
* 2:aliyun-java-sdk-dysmsapi.jar
实现的代码可以从demo中拷贝，稍作修改即可
3、异常处理
集成后，在main方法中运行一切正常，但是当项目跑起来以后，触发短信发送时，却发生了异常，内容如下：

可见caused by gnu.xml.dom.DomElement，问题出在这个类，而这个类在 gnujaxp.jar 中，于是我删除了这个jar包，重新编译项目后，运行一切正常。
