08年了,我也把07年所做的工作总结一下。望各位朋友不吝指教。
一、名词解释 SMPP:短消息点对点协议,SMPP协议是一个国际标准,有SMS论坛制定,官方网址为smsforum.net,截至2006年7月2日,最新版本是5.0。曾经流行的版本是3.3、3.4。SMPP协议向后兼容的。
二、简要介绍
主要程序介绍:
三、主体程序介绍 while (keepRunning) { System.out.println(); System.out.println("- 1 start listener"); System.out.println("- 2 stop listener"); System.out.println("- 3 client"); System.out.println("- 4 start deliverMessage"); System.out.println("- 5 stop deliverMessage"); System.out.println("- 0 exit"); System.out.print("> "); optionInt = -1; try { option = keyboard.readLine(); optionInt = Integer.parseInt(option); } catch (Exception e) { optionInt = -1; } switch (optionInt) { case 1: startlistener(); break; case 2: stoplistener(); break; case 3: listclienter(); break; case 4: startdeliverMessage(); break; case 5: stopdeliverMessage();

try { Connection connection = null; serverConn.setReceiveTimeout(getAcceptTimeout()); connection = serverConn.accept(); if (connection != null) { SMSCSession session = new SMSCSession(connection); session.setHashSet(hashSet); Thread thread = new Thread(session); thread.start(); sessionFactory.register(session); debug.write("SMSCListener launched a session on the accepted connection."); } else { debug.write("no connection accepted this time."); } } catch (InterruptedIOException e) { debug.write("InterruptedIOException accepting, timeout? -> " + e); } catch (IOException e) { event.write(e, "IOException accepting connection"); keepReceiving = false; }

因为时间比较紧,系统是在logica smsc的基础修改完成的,本人1周完成。主是加入了业务所需要的东西。因涉及非技术问题,此处只取了一部份代码。
ps: 做这个项目的时候,主要是为适应xx省smsc经过huiway改造之后的话单分检,大家开始都没有注意有可能出现这种情况,时间紧(大约只有1周时间),压力大(自己以前还没有smsc角色的程序,对smpp中的DeliverSM消息不太熟,后来果然在上面载了跟头,测试时总发现下发出去的消息是乱码,反复测试,编码格式也换了9种,后来才发现有个DeliverSM中的setDataCoding没有设置,郁闷),经过自己的努力和同事的帮助。基本上在一周内完成,包括测试用例。 现在这个系统已上线,到目前为止已正常运行2个月,从未出现过大问题。运行平台为redhat enterprise 4。
