需求分析和环境搭建
需求分析
用户在体检之前需要进行预约,可以通过电话方式进行预约,此时会由体检中心客服人员通过后台系统录入预约信息。用户也可以通过手机端自助预约。本章节开发的功能为用户通过手机自助预约。
预约流程如下:
1、访问移动端首页
2、点击体检预约进入体检套餐列表页面
3、在体检套餐列表页面点击具体套餐进入套餐详情页面
4、在套餐详情页面点击立即预约进入预约页面
5、在预约页面录入体检人相关信息点击提交预约
效果如下图:
搭建移动端工程
本项目是基于SOA架构进行开发,前面我们已经完成了后台系统的部分功能开发,在后台系统中都是通过Dubbo调用服务层发布的服务进行相关的操作。本章节我们开发移动端工程也是同样的模式,所以我们也需要在移动端工程中通过Dubbo调用服务层发布的服务,如下图:
导入maven坐标
在health_common工程的pom.xml文件中导入阿里短信发送的maven坐标
<dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-core</artifactId> <version>3.3.1</version> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-dysmsapi</artifactId> <version>1.0.0</version> </dependency>
导入通用组件
在health_common工程中导入如下通用组件
ValidateCodeUtils工具类:
package com.itheima.utils; import java.util.Random; /** * 随机生成验证码工具类 */ public class ValidateCodeUtils { /** * 随机生成验证码 * @param length 长度为4位或者6位 * @return */ public static Integer generateValidateCode(int length){ Integer code =null; if(length == 4){ code = new Random().nextInt(9999);//生成随机数,最大为9999 if(code < 1000){ code = code + 1000;//保证随机数为4位数字 } }else if(length == 6){ code = new Random().nextInt(999999);//生成随机数,最大为999999 if(code < 100000){ code = code + 100000;//保证随机数为6位数字 } }else{ throw new RuntimeException("只能生成4位或6位数字验证码"); } return code; } /** * 随机生成指定长度字符串验证码 * @param length 长度 * @return */ public static String generateValidateCode4String(int length){ Random rdm = new Random(); String hash1 = Integer.toHexString(rdm.nextInt()); String capstr = hash1.substring(0, length); return capstr; } }
SMSUtils工具类:
package com.itheima.utils; import com.aliyuncs.DefaultAcsClient; import com.aliyuncs.IAcsClient; import com.aliyuncs.dysmsapi.model.v20170525.SendSmsRequest; import com.aliyuncs.dysmsapi.model.v20170525.SendSmsResponse; import com.aliyuncs.exceptions.ClientException; import com.aliyuncs.http.MethodType; import com.aliyuncs.profile.DefaultProfile; import com.aliyuncs.profile.IClientProfile; /** * 短信发送工具类 */ public class SMSUtils { public static final String VALIDATE_CODE = "SMS_159620392";//发送短信验证码 public static final String ORDER_NOTICE = "SMS_159771588";//体检预约成功通知 /** * 发送短信 * @param phoneNumbers * @param param * @throws ClientException */ public static void sendShortMessage(String templateCode,String phoneNumbers,String param) throws ClientException{ // 设置超时时间-可自行调整 System.setProperty("sun.net.client.defaultConnectTimeout", "10000"); System.setProperty("sun.net.client.defaultReadTimeout", "10000"); // 初始化ascClient需要的几个参数 final String product = "Dysmsapi";// 短信API产品名称(短信产品名固定,无需修改) final String domain = "dysmsapi.aliyuncs.com";// 短信API产品域名(接口地址固定,无需修改) // 替换成你的AK final String accessKeyId = "accessKeyId";// 你的accessKeyId,参考本文档步骤2 final String accessKeySecret = "accessKeySecret";// 你的accessKeySecret,参考本文档步骤2 // 初始化ascClient,暂时不支持多region(请勿修改) IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou", accessKeyId, accessKeySecret); DefaultProfile.addEndpoint("cn-hangzhou", "cn-hangzhou", product, domain); IAcsClient acsClient = new DefaultAcsClient(profile); // 组装请求对象 SendSmsRequest request = new SendSmsRequest(); // 使用post提交 request.setMethod(MethodType.POST); // 必填:待发送手机号。支持以逗号分隔的形式进行批量调用,批量上限为1000个手机号码,批量调用相对于单条调用及时性稍有延迟,验证码类型的短信推荐使用单条调用的方式 request.setPhoneNumbers(phoneNumbers); // 必填:短信签名-可在短信控制台中找到 request.setSignName("传智健康"); // 必填:短信模板-可在短信控制台中找到 request.setTemplateCode(templateCode); // 可选:模板中的变量替换JSON串,如模板内容为"亲爱的${name},您的验证码为${code}"时,此处的值为 // 友情提示:如果JSON中需要带换行符,请参照标准的JSON协议对换行符的要求,比如短信内容中包含\r\n的情况在JSON中需要表示成\\r\\n,否则会导致JSON在服务端解析失败 request.setTemplateParam("{\"code\":\""+param+"\"}"); // 可选-上行短信扩展码(扩展码字段控制在7位或以下,无特殊需求用户请忽略此字段) // request.setSmsUpExtendCode("90997"); // 可选:outId为提供给业务方扩展字段,最终在短信回执消息中将此值带回给调用者 // request.setOutId("yourOutId"); // 请求失败这里会抛ClientException异常 SendSmsResponse sendSmsResponse = acsClient.getAcsResponse(request); if (sendSmsResponse.getCode() != null && sendSmsResponse.getCode().equals("OK")) { // 请求成功 System.out.println("请求成功"); } } }
RedisMessageConstant常量类:
package com.itheima.constant; public class RedisMessageConstant { public static final String SENDTYPE_ORDER = "001";//用于缓存体检预约时发送的验证码 public static final String SENDTYPE_LOGIN = "002";//用于缓存手机号快速登录时发送的验证码 public static final String SENDTYPE_GETPWD = "003";//用于缓存找回密码时发送的验证码 }
health_mobile
创建移动端工程health_mobile,打包方式为war,用于存放Controller,在Controller中通过Dubbo可以远程访问服务层相关服务,所以需要依赖health_interface接口工程。
