Message Modem Develop

一、SMSLib简介

调用短信猫，都是通过串口通讯和AT命令发中文短信要采用PDU模式，文字要经过PDU编码。这些事情网上的开源项目SMSLib已经已经帮我们做了。

SMSLib是一个开放源代码的短信猫二次开发包，有JAVA和.Net两个版本，目前最新版为v3.5.2。Official Website：http://smslib.org/

                                                                                                                                                                       图1-1

二、Window平台


1、在smslib官网下载“SMSLib for Java v3.5.2”开发包，并解压，目录结构如下图所示：

                                                                        图2-1


                                                                        图2-2

lib：存放二次开发包（smslib-3.5.2.jar）和运行时的依赖包（slf4j、log4j、commons-net、jsmpp等）（重要）

dist：存放短信猫服务开发包（smsserver-3.5.2.jar），该包包括了smslib-3.5.2.jar中的所有核心类。如果是将短信猫作为服务的方式部署，不需要额外写代码开发短信发送和接收的接口，直接部署短信服务即可，详细的步聚，可以参考《短信猫服务安装与配置指南》。（重要）

doc：smslib介绍、使用指南、smsserver安装与配置等文档（重要）

javadoc：二次开发包API

src：存放二次开发包源码和示例源码

misc：smslib日志（log4j）配置配置模板、smsserver数据库建库脚本及服务接口等文件

build：项目管理相关文件（不重要）


2、下载SUN JavaComm v2 (Win32)动态库，并解压，目录结构如下图所示：


                                                                        图3-1

3、运行环境配置

  • 复制“图3-1”中javax.comm.properties文件到%JAVA_HOME%\jre\lib目录下，win32com.dll文件到%JAVA_HOME%\jre\bin目录下
  • 复制“图3-1”中comm.jar和图2-2中所有jar文件到CLASSPATH目录下（如果是用eclipse等IDE工具，将这些jar包导入到工程中)

       注意： win32com.dll只支持32位jdk

4、运行示例程序并测试
      修改图2-1中src\java\examples\modem目录下的SendMessage.java和ReadMessages.java程序发送短信的参数配置，编译并运行。如下图所示：
// SendMessage.java - Sample application.
// 短信发送测试程序
// This application shows you the basic procedure for sending messages.
// You will find how to send synchronous and asynchronous messages.
//
// For asynchronous dispatch, the example application sets a callback
// notification, to see what's happened with messages.

		115200：串口每秒发送数据的bit位数,必须设置正确才可以正常发送短信，可通过程序进行检测。常用的有115200、9600

		System.in.read();
		Service.getInstance().stopService();
	}

三、Linux、Unix、Solaris平台
与window平台不同的地方就在于动态库和二次开发包不一致，其它基本类似
1、下载RxTx v2.1.7 R2
2、解压，目录结构如下图所示：

                                                                        图4-1
3、运行环境配置
  • 复制图4-1中Linux目录下的librxtxSerial.so文件至$JAVA_HOME/jre/lib/$(ARCH)/目录下，复制RXTXcomm.jar到应用程序的CLASSPATH或$JAVA_HOME/jre/lib/ext目录下
  • 复制图3-1中的javax.comm.properties文件至$JAVA_HOME/jre/lib目录下，并将文件中的Driver=com.sun.comm.Win32Driver改成Driver=gnu.io.CommDriver。文件内容如下图所示：
4、修改示例程序，编译并运行

四、短信猫设备可用端口检测程序
import gnu.io.*;
import java.util.*;
import java.io.*;

public class CommTest
{
	static CommPortIdentifier portId;
	static Enumeration portList;
	static int bauds[] = { 9600, 19200, 57600, 115200 };	//检测端口所支持的波特率

	public static void main(String[] args)
	{
		portList = CommPortIdentifier.getPortIdentifiers();
		System.out.println("短信设备端口连接测试...");
		while (portList.hasMoreElements())
		{
			portId = (CommPortIdentifier) portList.nextElement();
			if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL)
			{
				System.out.println("找到串口: " + portId.getName());
				for (int i = 0; i < bauds.length; i++)
				{
					System.out.print("	Trying at " + bauds[i] + "...");
					try
					{
						SerialPort serialPort;
						InputStream inStream;
						OutputStream outStream;
						int c;
						String response;
						serialPort = (SerialPort) portId.open("SMSLibCommTester", 1971);
						serialPort.setFlowControlMode(SerialPort.FLOWCONTROL_RTSCTS_IN);
						serialPort.setSerialPortParams(bauds[i], SerialPort.DATABITS_8, SerialPort.STOPBITS_1, SerialPort.PARITY_NONE);
						inStream = serialPort.getInputStream();
						outStream = serialPort.getOutputStream();
						serialPort.enableReceiveTimeout(1000);
						c = inStream.read();
						while (c != -1)
							c = inStream.read();
						outStream.write('A');
						outStream.write('T');
						outStream.write('\r');
						try
						{
							Thread.sleep(1000);
						}
						catch (Exception e)
						{
						}
						response = "";
						c = inStream.read();
						while (c != -1)
						{
							response += (char) c;
							c = inStream.read();
						}
						if (response.indexOf("OK") >= 0)
						{
							try
							{
								System.out.print("  获取设备信息...");
								outStream.write('A');
								outStream.write('T');
								outStream.write('+');
								outStream.write('C');
								outStream.write('G');
								outStream.write('M');
								outStream.write('M');
								outStream.write('\r');
								response = "";
								c = inStream.read();
								while (c != -1)
								{
									response += (char) c;
									c = inStream.read();
								}
								System.out.println("  发现设备: " + response.replaceAll("\\s+OK\\s+", "").replaceAll("\n", "").replaceAll("\r", ""));
							}
							catch (Exception e)
							{
								System.out.println("  没有发现设备!");
							}
						}
						else System.out.println("  没有发现设备!");
						serialPort.close();
					}
					catch (Exception e)
					{
						System.out.println("  没有发现设备!");
					}
				}
			}
		}
	}
}

注意事项：

1、使用smslib库之前，如果你的设备是usb数据线，先检查系统中该设备驱动程序是否已安装，在window环境下，厂商一般会提供设备的驱动程序，在linux环境下，内核2.6.32或以上版本，预装了常用设备的USB转串口驱动，如果系统未自动识别该设备，就需要自行安装该设备的驱动程序了。

2、在开发过程中，org.smslib.TimeoutException: No response from device是最常遇到的一个异常，解决方案请参考：短信猫JAVA二次开发包SMSLib，org.smslib.TimeoutException: No response from device解决方案


最近在Linux环境下利用开源组件SMSLib，开发短信猫应用，经常遇到这个错误，发现网上也有很多朋友遇到过这个问题，现在将解决这个问题的方案分享给大家。


开发环境：

            Linux ReadHat5.4   64位，内核：2.6.33.20 ，JDK1.6，SMSServer-3.5.2.jar


异常信息：

图1-1


解决方案：

遇到这个异常时，请检查以下二个方面：

1、是否启用轮循模式？

方式1）、在jvm中，添加-Dsmslib.serial.polling启动参数

方式2）、在JAVA代码中，在调用startService之前，显示启用轮循模式

[java] view plaincopy
  1. Service.getInstance().S.SERIAL_POLLING = true;  //启用轮循模式  

2、创建串口网关对象时，是否设置了正确的短信猫设备生产厂商？

[java] view plaincopy
  1. SerialModemGateway gateway = new SerialModemGateway("modem.com1", "/dev/ttyUSB1", 9600, "Wavecom", "型号");  

参数说明：

 modem.com1：网关ID（即短信猫端口ID，多个短信猫时，用于标识是由哪个口发出的短信）
 /dev/ttyUSB1：串口名称（USB转串口，短信猫中的所有端口自动被操作系统映射到/dev/目录下，以ttyUSB*开头的文件上，前提是系统预装有USB转串口的驱动），注：Linux下2.6.32以上内核已预装USB串口设备驱动，如果低版本的内核，未检测到USB设备，则需要自己安装驱动或升级内核。

 9600：波特率，根据二次开发包中的CommTest.java测试程序，检测你的设备所支持的波特率。

 Wavecom：生产厂商名称，必须设置正确，否则SMSLib在初始设备时，会报No response from Device异常，原因是SMSLib为不同的生产厂商，有相应的AT指定接口实现，见下图：

图1-2

在“图1-1“中，是因为我在创建串口网关对象是，指定了厂商名称为“HuaWei“，所以报了如图1-3所示异常：


图1-3

 型号：可以不用指定，如果指定了型号，SMSLib在初始化设备的时候，会找特定型号的AT指令实现类，如果没找到有可能会出现初始化设备异常，但据我测试，如果没有找到指定厂商指定的型号的AT指令实现，会去指定厂商的通用实现接口

    以上异常是基于SMSServer-3.5.2在Linux环境下开发所遇到的一些问题，和大家分享，Window上也会有相类似的问题，可参考上面的解决思路去寻找解决方案，另外短信猫二次开发包还有其它的厂商进行了底层AT指令的封装，比如：jindiJavaSms(金笛)开发包，用它时，我也遇到了类似的问题，解决方式也和上面差不多，只不过可能参数有些不同，在这里不做详细介绍，如有遇到同样问题的朋友，欢迎大家讨论！
