SMSLib实现Java短信收发的功能

    blog迁移至: http://www.micmiu.com

    用java实现短信收发的功能，目前一般项目中短信群发功能的实现方法大致有下面三种：

• 1、 向运行商申请短信网关，不需要额外的设备，利用运行商提供的API调用程序发送短信，适用于大型的通信公司。
• 2、 借助像GSM MODEM之类的设备（支持AT指令的手机也行），通过数据线连接电脑来发送短信，这种方法比较适用于小公司及个人。要实现这种方式必须理解串口通信、AT指令、短信编码、解码。
• 3、 借助第三方运行的网站实现，由网站代发短信数据，这种方法对网站依赖性太高，对网络的要求也比较高。

       鉴于项目的情况和多方考虑，同时又找到了一个开源的SMSLib项目的支持，比较倾向于第二种方法，SMSLib的出现就不需要我们自己去写底层的AT指令，这样就可以直接通过调用SMSLib的API来实现通过GSM modem来收发送短信了。

SMSLib官方网站：http://smslib.org/，使用SMSLib的一些基本要点：

• SUN JDK 1.6 or newer. （Java环境）
• Java Communications Library. （Java串口通信）
• Apache ANT for building the sources. （编译源码时需要的）
• Apache log4j. （日志工具）
• Apache Jakarta Commons - NET. （网络操作相关的）
• JSMPP Library （SMPP协议时需要的）

有关Java串口通信需要补充说明：

• window系统可以用SUN Java Comm v2. （该版本好像也支持solaris）
         其下载地址： http://smslib.googlecode.com/files/javacomm20-win32.zip
• 其他操作系统(比如：Linux, Unix, BSD,等等),你可以选择 Java Comm v3 或者是RxTx。
         Java Comm v3下载地址： http://java.sun.com/products/javacomm/（需要注册）；
         RxTx官网： http://users.frii.com/jarvi/rxtx/index.html or http://rxtx.qbang.org/wiki/index.php/Main_Page

附件提供相关下载：

• java串口通信v2：javacomm20-win32.zip
• smslib-3.5.1.jar
• 短信 modem驱动：PL2303_Prolific_DriverInstaller_v130.zip

本次测试的环境是window，GSM modem是wavecom，所以这次主要描述window环境下简单的实现过程：
【一】、配置相应的环境
      首先解压下载的Java Comm v2文件javacomm20-win32.zip，具体配置步骤如下：

• 把文件：comm.jar copy 到目录：<JDKDIR>/jre/lib/ext/，当然这一步也可以不要这样做，你只需把comm.jar copy到所要运行的项目对应的lib/下既可
• 把文件：javax.comm.properties copy 到目录：<JDKDIR>/jre/lib/
• 把DLL文件：win32com.dll（windows） copy 到目录：<JDKDIR>/jre/bin/
• 如果存在JRE目录, 最好按照上面步骤把文件copy到<JREDIR>相应的目录下

【二】、测试串口端口程序：
TestGetPortList.java

package michael.comm.serial;

import java.util.Enumeration;

import javax.comm.CommDriver;
import javax.comm.CommPortIdentifier;
import javax.comm.SerialPort;

    public static void main(String[] args) throws Exception {
        // 人工加载驱动
        // MainTest.driverInit();
        TestGetPortList.getCommPortList();
        // 人工加载驱动获取端口列表
        // TestGetPortList.getPortByDriver();

    }

    /**
     * 手工加载驱动<br>
     * 正常情况下程序会自动加载驱动，故通常不需要人工加载<br>
     * 每重复加载一次，会把端口重复注册，CommPortIdentifier.getPortIdentifiers()获取的端口就会重复
     */
    public static void driverManualInit() {
        String driverName = "com.sun.comm.Win32Driver";
        String libname = "win32com";
        CommDriver commDriver = null;
        try {
            System.loadLibrary("win32com");
            System.out.println(libname + " Library Loaded");

            commDriver = (javax.comm.CommDriver) Class.forName(driverName)
                    .newInstance();
            commDriver.initialize();
            System.out.println("comm Driver Initialized");

        } catch (Exception e) {
            System.err.println(e);
        }
    }

    /**
     * 获取端口列表
     */
    public static void getCommPortList() {
        CommPortIdentifier portId;
        Enumeration portEnum = CommPortIdentifier.getPortIdentifiers();
        while (portEnum.hasMoreElements()) {
            portId = (CommPortIdentifier) portEnum.nextElement();

            if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {
                System.out.println("串口: name-" + portId.getName()
                        + " 是否占用-" + portId.isCurrentlyOwned());
            } else {
                System.out.println("并口: name-" + portId.getName()
                        + " 是否占用-" + portId.isCurrentlyOwned());
            }
        }
        System.out.println("-------------------------------------");
    }

    /**
     * 
     */
    public static void getPortByDriver() {

        String driverName = "com.sun.comm.Win32Driver";
        String libname = "win32com";
        CommDriver commDriver = null;
        try {
            System.loadLibrary("win32com");
            System.out.println(libname + " Library Loaded");

            commDriver = (CommDriver) Class.forName(driverName).newInstance();
            commDriver.initialize();
            System.out.println("comm Driver Initialized");

        } catch (Exception e) {
            System.err.println(e);
        }
        SerialPort sPort = null;
        try {

            sPort = (SerialPort) commDriver.getCommPort("COM24",
                    CommPortIdentifier.PORT_SERIAL);
            System.out.println("find CommPort:" + sPort.toString());
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }

    }

}
