# ……1.需求…… #

用户提交订单申请，需要输入手机号，验证二维码。然后再判断用户输入的手机号是否正确，正确则生成订单信息入库。

# ……2.实现…… #

实现的思路是，1.发送二维码 2.验证二维码和redis中存放的是否一致 3.生成订单入库

1.发送二维码，其实是Java代码生成的随机数字，再用httpclient请求发短信的服务，输入用户名密码等参数信息，第一步就完成了。需要将验证码存入redis中，在第二步验证中用得到。

controller：

//	http://managerapi.cuco.cn/order/getVerificationCode
    //	{"memberMobile":"15633296156"}
    	//获取验证码--zhouzhou--2017年5月6日14:21:14
    	@API(value = "获取验证码")
    	@RequestMapping(value = "/v1/order/getVerificationCode", method = RequestMethod.POST)
    	public Object getVerificationCode(@RequestBody Order order) {
    		ParamVerifyUtils.paramNotNull(order.getMemberMobile(), "获取验证码中手机号没有填写");
    		System.out.println("手机号为：" + order.getMemberMobile());
    		if (!PhoneFormatCheckUtils.isPhoneLegal(order.getMemberMobile())) {
    			ResponseUtil.toFailureBody(ServerStatus.SHOW_ERROR, "请填写真实手机号。");
    		}
    		Member member = new Member();
    		member.setMobile(order.getMemberMobile());
    
    		Member memberinfo = this.memberService.getMemberByMobile(member.getMobile());
    		if (memberinfo != null) {
    			ExceptionUtil.throwWarn("您已成功提交申请，销售人员稍后会和您联系。");
    		}
    		String identifyCode = SMSUtils.getFourRandom();
    		SMSUtils.sendMessage(member.getMobile(), identifyCode);
    
    		JedisUtils.set("identifyCode" + order.getMemberMobile(), identifyCode, 120);
    		System.out.println("生成验证码--" + identifyCode);
    		return identifyCode;
    	}

工具类：

get请求记得utf-8转码哟，否则手机会收到一堆小方格格。

public class SMSUtils {
    
    	protected Logger logger = Logger.getLogger(this.getClass());
    
    	public static boolean sendMessage(String mobile, String identifyCode) {
    		boolean result = false;
    		String userId = "马赛克";
    		String password = "马赛克";
    		String pszMobis = mobile;
    		String pszMsg = "正式完成短信验证" + "【" + identifyCode + "】";// +
    		String iMobiCount = "1";
    		String pszSubPort = "*";
    		String MsgId = RandomStringUtils.randomNumeric(19);
    		try {
    			String url = "是一串URL马赛克"//
    					+ "userId=" + userId//
    					+ "&password=" + password//
    					+ "&pszMobis=" + pszMobis//
    					+ "&pszMsg=" + pszMsg//
    					+ "&iMobiCount=" + iMobiCount//
    					+ "&pszSubPort=" + pszSubPort//
    					+ "&MsgId=" + MsgId;
    			// RelyHttpClient.sendGet(url, null, "UTF-8");
    			// String responseBody = HttpClientUtils.sendGet(url, null,"UTF-8");
    			String responseBody = HttpClientUtils.sendGet(url, null,"UTF-8");
    
    			if (StringUtils.isNotBlank(responseBody)) {
    				String sub = responseBody.substring(74, responseBody.lastIndexOf("</string>"));
    				System.out.println("截取返回值=================" + sub);
    				if (sub.length() > 15) {// 返回值长度大于15则表示成功
    					result = true;
    					System.out.println("验证码发至{}送成功" + mobile);
    				} else {
    					System.out.println("验证码发至{}失败{}" + mobile + responseBody);
    				}
    			}
    		} catch (Exception e) {
    			System.out.println("验证码发至{}异常{}" + mobile + e.getMessage());
    
    		}
    
    		return result;
    	}
    
    	/**
    	 * 产生4位随机数(0000-9999)
    	 * 
    	 * @return 4位随机数
    	 */
    	public static String getFourRandom() {
    		Random random = new Random();
    		String fourRandom = random.nextInt(10000) + "";
    		int randLength = fourRandom.length();
    		if (randLength < 4) {
    			for (int i = 1; i <= 4 - randLength; i++)
    				fourRandom = "0" + fourRandom;
    		}
    		return fourRandom;
    	}

2.验证二维码和redis中存放的是否一致

@API("提交订单")
    	@RequestMapping(value = "/v1/commit_order/pre_create",method = RequestMethod.POST)
    	public Object preCreateOrder(@RequestBody Order order){
    
    		//1.判断是否为空 
    		ParamVerifyUtils.paramNotNull(order, "订单不能为空");
    		ParamVerifyUtils.paramNotNull(order.getMemberName(), "会员姓名不能为空");
    		ParamVerifyUtils.paramNotNull(order.getMemberMobile(), "会员手机号不能为空");
    		ParamVerifyUtils.paramNotNull(order.getStatus(), "订单状态不能为空");
    		ParamVerifyUtils.paramNotNull(order.getOrderFrom(), "订单来源不能为空");
    		ParamVerifyUtils.paramNotNull(order.getVerificationCode(), "验证码不能为空");
    		if (!PhoneFormatCheckUtils.isPhoneLegal(order.getMemberMobile())) {
    
    			ResponseUtil.toFailureBody(ServerStatus.SHOW_ERROR, "请填写真实手机号。");
    		}
    		
    		String identifyCode = JedisUtils.get("identifyCode" + order.getMemberMobile());
    		if (StringUtils.isEmpty(identifyCode) || !identifyCode.equals(order.getVerificationCode())) {
    			ResponseUtil.toFailureBody(ServerStatus.SHOW_ERROR, "验证码不正确，请重新获得验证码");
    
    		    
    		}
    		//2.调用service插入
    		return orderService.createOrder(order);
    		
    	}

3.生成订单入库

//创建订单--zhouzhou--2017年5月6日15:21:14
    	@Override
    	public Order createOrder(Order order) {
    //		 会员姓名、会员手机号、订单状态（1.待处理）、remark、order_from、订单编号(年月日＋8位随机数)
    		//1.判断是否为空
    		ParamVerifyUtils.paramNotNull(order, "订单不能为空");
    		ParamVerifyUtils.paramNotNull(order.getMemberName(), "会员姓名不能为空");
    		ParamVerifyUtils.paramNotNull(order.getMemberMobile(), "会员手机号不能为空");
    		ParamVerifyUtils.paramNotNull(order.getStatus(), "订单状态不能为空");
    		ParamVerifyUtils.paramNotNull(order.getOrderFrom(), "订单来源不能为空");
    
    		//2.生成订单编号
    		SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMdd");
    		Date date =new Date();
    		String str_date = sdf.format(date);
    		
    		StringBuilder str=new StringBuilder();//定义变长字符串
    		Random random=new Random();
    		//随机生成数字，并添加到字符串
    		for(int i=0;i<8;i++){
    		    str.append(random.nextInt(10));
    		}
    		//将字符串转换为数字并输出
    		int num=Integer.parseInt(str.toString());
    		
    		String order_num=str_date+num;
    		System.out.println(order_num);
    		
    		//3.set 订单编号
    		order.setOrderNum(order_num);
    		order.setCreated(date);
    		//4.插入
    		orderMapper.insertSelective(order);
    		
    		return order;
    	}

效果，哦，就是我手机上的短信==

# ……3.总结…… #

实现很简单，就是用了个httpclient请求端口。然后存储在redis中，方便获取。提高获取的效率。多实践，多总结。
