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

导入通用组件

在health_common工程中导入如下通用组件

ValidateCodeUtils工具类:

    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;

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。
