一般来说,对于信息的处理无外乎两种方式:一种是把任务保存到缓存队列中,然后去调度任务.优点就是速度快,缺点也很明显,如果任务处理的不好,很容出现任务无法执行或者等待.另一种就是保存到数据库中,短信发送和数据的处理分开处理,但是速度方面会有影响.这里说的第二种方法.
首先把任务的数据保存到数据库中,这块的话没有什么难度,就是普通的增删改查.
发送短信的单独分离出来运行,既web端和发送端分开.
首先需要初始化设备
public static void initDriver() {
if (!initDriver) {
initDriver = true;
String driverName = "com.sun.comm.Win32Driver";
String libname = "win32com";
CommDriver commDriver = null;
try {
System.loadLibrary("win32com");
log.info(libname + " Library Loaded");
commDriver = (CommDriver) Class.forName(driverName)
.newInstance();
commDriver.initialize();
log.info("comm Driver Initialized");
} catch (Exception e) {
log.error(e.getMessage(), e);
}
}
}
然后需要查找SMS设备
public static List<String> findSMS() {
TreeMap<String, String> portsMap = new TreeMap<String, String>();
log.info("GSM Modem 串行端口连接测试开始...");
Enumeration<?> en = CommPortIdentifier.getPortIdentifiers();
CommPortIdentifier portId;
while (en.hasMoreElements()) {
portId = (CommPortIdentifier) en.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {
if (checkCommPortForSMS(portId.getName())) {
log.info(" 设备端口 ： " + portId.getName() + " 满足短信发送要求");
portsMap.put(portId.getName(), portId.getName());
}
}
}
log.info("GSM Modem 检查结束 ...");
return new Vector<String>(portsMap.keySet());
}
public static boolean checkCommPortForSMS(String portName) {
portList = CommPortIdentifier.getPortIdentifiers();
while (portList.hasMoreElements()) {
portId = (CommPortIdentifier) portList.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL
&& portName.equals(portId.getName())) {
log.info("找到串口: " + portId.getName());
for (int i = 0; i < bauds.length; i++) {
log.info(" Trying at " + bauds[i] + "...");
try {
SerialPort serialPort;
InputStream inStream;
OutputStream outStream;
int c;
StringBuffer response = new StringBuffer();
serialPort = (SerialPort) portId.open(
"SMSLibCommTester", 2000);
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) {
log.error(e.getMessage(), e);
}
c = inStream.read();
while (c != -1) {
response.append((char) c);
c = inStream.read();
}
if (response.indexOf("OK") >= 0) {
log.info(" 正在检测设备:");
try {
outStream.write('A');
outStream.write('T');
outStream.write('+');
outStream.write('C');
outStream.write('G');
outStream.write('M');
outStream.write('M');
outStream.write('\r');
response = new StringBuffer();
c = inStream.read();
while (c != -1) {
response.append((char) c);
c = inStream.read();
}
log.info(" 发现设备: "
+ response.toString().replaceAll(
"(\\s+OK\\s+)|[\n\r]", ""));
if (!"ERROR".equals(response.toString()
.replaceAll("(\\s+OK\\s+)|[\n\r]", "")
.trim())) {
serialPort.close();
inStream.close();
outStream.close();
return true;
}
return false;
} catch (Exception e) {
log.info(" 检测设备失败,获取设备信息异常：" + e.getMessage());
}
} else {
log.info(" 检测设备失败，没有接收到响应结果!");
}
serialPort.close();
} catch (Exception e) {
log.info(" 检测设备失败，发生异常：" + e.getMessage());
}
}
}
}
return false;
}
调用结束后会返回当前计算机可用的端口号,然后就可以注册gateway了
for (String portId : ports) {
SerialModemGateway gateway = new SerialModemGateway(
"modem.MAGUS" + portId, portId, 9600, "wavecom", "");
gateway.setInbound(true);
gateway.setOutbound(true);
smsService.addGateway(gateway);
}
然后需要设置smsService的各种监听事件了.这些都搞定之后就可以设置一个while(true)循环去不停的读取数据库发送短信了,但是有一点,需要设置一个安全的线程去执行,同时还要添加同步锁.保证当前只有一个工作在进行.
网上有很多简单的方法,可以结合着学习.直接贴代码的话就没意思了.
