1. 技术架构和流程

定义-开发-维护阶段

如下后台管理系统给管理人员，微信端给患者。

2.数据库建模工具使用

File-New

3.环境搭建

3.1 项目结构

health_parent：父工程，打包方式为pom，统一锁定依赖的版本，同时聚合其他子模块便于统一执行maven命令
health_common：通用模块，打包方式为jar，存放项目中使用到的一些工具类和常量类
health_pojo：打包方式为jar，存放实体类和返回结果类等
health_mapper：持久层模块，打包方式为jar，存放mapper接口和Mapper映射文件等
health_interface：打包方式为jar，存放服务接口
如下两个war包：
health_service： Dubbo服务模块，打包方式为war，存放服务实现类，作为服务提供方，需要部署到tomcat运行，服务生产者
health_web：打包方式为war，作为Dubbo服务消费方，存放Controller、HTML页面、js、css、spring配置文件等，需要部署到tomcat运行

3.2 maven项目搭建

3.2.1 创建health_parent父工程

创建health_parent，父工程，打包方式为pom，用于统一管理依赖版本。

6.页面布局分析

请求怎么发，有什么响应数据，请求url有了，可以写controller方法，再service层，再mapper数据库。
分页查询有三个参数：当前页的页码，页面大小pagesize（每页显示多少条记录），条件查询的条件要获取到。

上面的这三个参数怎么传？定义了一个map格式json数据，这三个key是QueryPageBean.java中三个属性名称一样。所以把这json数据提交时，首先后端接json数据，request body接json数据，接收完后自动封装到QueryPageBean对象中。

查询的分页数据都是封装在PageResult中，总记录数，每页数据封装到PageResult中，再把PageResult封装到Result.java的data属性中。

spring并不是很智能，告诉它怎么做才会做（每次告知代码都一样），如创建一个web项目，要配ssm的springmvc的，要配DispatcherServlet，要配Listen监听器，整合mybatis的话依赖整合包，所以每次操作基本样式一致，业务不一致【其实业务还好，业务有自己的特点：业务control调service，service调mapper，做结果返回】。

springBoot只需要引入一个依赖即springweb启动器就完了，0配置。但并不是所有东西都能做到这点，如数据库做不到这点，因为数据库各不相同。约定大于配置，除了mybatis外，我们彻底拒绝xml，全部换成注解配置。
