1、生成驗證碼類

package com.util;

import java.util.Timer;
import java.util.TimerTask;

/**
 * @description 手機發送驗證碼工具類
 */
public class MessageCode extends TimerTask{

	private Timer timer;
	/**
	 * @description 簡訊驗證碼的內容
	 */
	private String messageCode;
	/**
	 * @description 毫秒,預設60秒後過期
	 */
	private long maXtime = 180000;
	/**
	 * @description 簡訊驗證碼長度
	 */
	private int length = 6;
	/**
	 * @description 簡訊驗證碼可取值
	 */
	private final String charOfMessage = "0123456789";
	//0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
	@Override
	public void run() {
		this.messageCode = null;//過期後簡訊驗證碼資訊置為null
		this.timer.cancel();
	}

	/**
	 * @decription 使用預設值
	 */
	public MessageCode() {
		super();
		this.timer = new Timer();
		genMessageCode(this.length);
		this.timer.schedule(this, this.maXtime);
	}

	/**
	 * @description 自定義最大過期時間，驗證碼最大長度
	 * @param maXtime
	 * @param length
	 */
	public MessageCode(long maXtime, int length) {
		super();
		this.maXtime = maXtime;
		this.length = length;
		genMessageCode(this.length);
		this.timer.schedule(this, this.maXtime);
	}

	/**
	 * @description 生成隨機驗證碼
	 * @param length
	 * @return void 返回值型別
	 
	 */
	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 index  = (int)(Math.floor(d * charOfMassegeLength) / 1);
			tempB.append(this.charOfMessage.charAt(index));
		}
		this.messageCode = tempB.toString();
	}
	/**
	 * @description 獲取驗證碼資訊，如果為空表示驗證碼超時
	 * @return
	 * @return String 返回值型別
		 */
	public String getMessageCode() {
		return messageCode;
	}

}
 

2、 MessageThread.java 執行緒類

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 使用執行緒傳送訊息，以免主執行緒等待

 */
public final class MessageThread implements Runnable{
	/**
	 * @description 傳送請求的URL
	 */
	private final static String url = "http:192.168.1.127/sms/send/smsSend.action?businessName=c1&isLong=3&appName=useraccount&smsKey=powsword";
	private String msg;
	private String phonenumber;
	
	@Override
	public void run() {
		sendMessage();
	}
	/**
	 * @description
	 * @return void 返回值型別

	 */
	private void sendMessage(){
		String phone = this.phonenumber;
		if(StringUtils.isBlank(this.phonenumber)){//手機號為空時，禁止訊息傳送
			return;
		}
		String tempUrl = url;
		try {
			//經過兩次轉碼。短訊息顯示正常
			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.net.URLEncoder.encode(msg, "UTF-8"));
			URLConnection connection = new URL(tempUrl).openConnection();
			connection.setConnectTimeout(2000);
			connection.setReadTimeout(2000);
			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 初始化傳送資訊執行緒資料
	 * @param msg 
	 * @param phonenumber
	 */
	public MessageThread(String msg, String phonenumber) {
		super();
		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、傳送訊息工具類

package com.util;

/**
 * @description <p>傳送訊息工具類，具體的訊息傳送方法參見MessageThread.java</p>
 * <p>呼叫sendMessage方法 ，傳入訊息內容和手機號傳送訊息。</p>
 * <p>當手機號為空時，不傳送訊息</p>

 */
public final class MessageUtil {

	
	/**
	* @description 呼叫此方法傳送訊息內容
	 * @param msg 傳送訊息內容
	 * @param phone 傳送訊息的手機號。當手機號為空時，不傳送訊息
	 */
	public final static void sendMessage (String msg, String phone){
		new Thread(new MessageThread(msg, phone)).start();
	}
}
