Java使用短信猫发信息(向串口发送AT指令)

使用Java发送短信息的方式有两种：

1>使用第三方平台的http请求进行发送，优点是接口简单，使用方便，发送的效率高，多条可以同时发送，缺点是短信平台，三大运营商不提供接口，都是第三方平台，但是第三方平台不稳定，如果倒闭，将意味着这套代码请求的服务器倒闭，则代码失效，需要再找另外的第三方公司；

2>硬件设备，短信猫，比如深圳宏电的H6221GPRS Mode模块，优点是发送稳定，不会出现担心第三方平台倒闭而重写代码的风险，缺点是需要硬件，资费是正常的短信价格，一台设备同一时间只能发送一条信息，成本较高；

下面给出使用短信猫发信息的Java代码：

5，测试类：

package sms;
 
 public class Test {
 	public static void main(String[] args) {
 		 final String str1 = "嘿嘿";
 		 		
 				
 		 final String str2 = "嘻嘻";
 		
 		Sms.sendSms("13311220311", "str1heihei", "COM6");
 //		new Thread(new Runnable() {
 //
 //			@Override
 //			public void run() {
 //				Sms.sendSms("13311220311", str1, "COM6");
 //			}
 //		}).start();
 //		new Thread(new Runnable() {
 //
 //			@Override
 //			public void run() {
 //				Sms.sendSms("13311220311", str2, "COM6");
 //			}
 //		}).start();
