实际上没多少技术含量，就是spring data jdbc+mysql 数据访问而且，主要就是几个参数配置
spring boot 项目结构
使用官方的初始化器

- 代码说明
RestApi.java 为简单查询，CntArticleDAO.java 为数据访问，application.properties 为jdbc 配置

启动效果
mvn spring-boot:run 
主要说明
jdbc 的版本以及ssl 配置参数，是最重要的，按照官方的介绍8以及最新的是不可以的（测试也是），支持ssl 的
jdbc 配置为jdbc:mysql://localhost:3307/appdemos?useSSL=true,同时官方也提供了一个auth 的扩展，可以参
