Using threads to create a tool class to send a phone verification code

1. Generate Verification Code class

Package Com.util;import java.util.timer;import java.util.timertask;/** * @description phone to send Captcha tool classes */public class Messagecode extends Timertask{private Timer timer;/** * @description SMS Verification Code content */private String messagecode;/** * @descript Ion MS, expires after 60 seconds */private long maxtime = 180000;/** * @description SMS Verification Code length */private int length = 6;/** * @description SMS */private final String charofmessage = "0123456789";// 0123456789abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz@overridepublic void Run () {This.messageCode = null;/ /After expiration SMS Verification code information is set to Nullthis.timer.cancel ();} /** * @decription Use default value */public Messagecode () {super () This.timer = new timer (); Genmessagecode (this.length); This.timer.schedule (this, this.maxtime);} /** * @description Custom Maximum expiration time, maximum captcha length * @param maxtime * @param length */public messagecode (long maxtime, int length) {Supe R (); this.maxtime = Maxtime;this.length = Length;genmessagecode (this.length); This.timer.schedule (this, this.maxtime) ;} /** * @description Generate random Verification code * @param length * @return void return value type */private final void genmessagecode (int length) {StringBuffer TEMPB = new StringBuffer (length); final int charofmassegelength = This.charOfMessage.length (); for (int i = 0; i < length; i++) {Double d = math.random (); int ind ex = (int) (Math.floor (d * charofmassegelength)/1); Tempb.append (This.charOfMessage.charAt (index));} This.messagecode = Tempb.tostring ();} /** * @description Gets the CAPTCHA information, if NULL indicates that the Authenticode timed out * @return * @return string return value type */public string Getmessagecode () {return Messageco De;}}

2. Messagethread.java Thread class

Package Com.util;import Java.io.bufferedreader;import Java.io.inputstreamreader;import java.net.URL;import Java.net.urlconnection;import org.apache.commons.lang.stringutils;/** * @description Use threads to send messages so that the main thread waits for */public final Class Messagethread implements runnable{/** * @description send the requested URL */private final static String url = "http:192.168.1.12 7/sms/send/smssend.action?businessname=c1&islong=3&appname=useraccount&smskey=powsword ";p rivate String Msg;private string PhoneNumber; @Overridepublic void Run () {sendMessage ();} /** * @description * @return void return value type */private void SendMessage () {String phone = this.phonenumber;if (Stringutils.isblan K (This.phonenumber)) {//Phone number is empty, prohibit message send return;} String Tempurl = url;try {//has been transcoded two times. The short message shows normal msg = Java.net.URLEncoder.encode (msg, "UTF-8"); Tempurl = (Tempurl + "&uuid=" + Java.util.UUID.randomUUID (). ToString (). ReplaceAll ("-", "")); Tempurl = (Tempurl + "&phone=" + phone); Tempurl = (Tempurl + "&content=" + java.ne T.urlencoder.encode (MSG, "UTF-8")); URLConnection connection = new URL (tempurl). OpenConnection (); Connection.setconnecttimeout (2000); Connection.setreadtimeout (+); Connection.connect (); BufferedReader reader = new BufferedReader (New InputStreamReader (Connection.getinputstream ()));//string x = Reader.readline ();//system.out.println (x); Reader.close ();} catch (Exception e) {e.printstacktrace ();}} /** * @decription Initialize send information thread data * @param msg * @param phonenumber */public messagethread (String msg, String phonenumber) {s Uper (); this.msg = Msg;this.phonenumber = PhoneNumber;} Public String getmsg () {return msg;} public void Setmsg (String msg) {this.msg = msg;} Public String Getphonenumber () {return phonenumber;} public void Setphonenumber (String phonenumber) {this.phonenumber = PhoneNumber;}}

3. Send Message Tool class

Package com.util;/** * @description <p> Send Message tool class, specific message sending method see Messagethread.java</p> * <p> Call the SendMessage method, the incoming message content and the phone number to send the message.  </p> * <p> do not send a message when the phone number is empty </p> */public final class Messageutil {/*** @description call this method to send message content * @param msg Send Message content * @param phone number for the message to be sent. When the phone number is empty, the message is not sent */public final static void SendMessage (String msg, string phone) {New Thread (new Messagethread (MSG, phone)). Start ();}}
