springboot新的开发模式：

1.jpa持久化规范，hibernate是具体的持久化实现。

2.orm对象关系映射，通过orm将内存中的数据持久化到数据库或者磁盘中永久保存。

3.jsp配置注意事项，需建立war项目，同时引入servlet,jstl,tomcat配置等，配置springMVC前缀，后缀，编写control。不建议使用jsp。

4.推荐使用thymelefe模板引擎技术事项jsp的功能，自带类似于jstl标签的功能。

5.文件夹解析：src/main/java/---java代码包括，entity,dao,service,controller基本的3层结构，另外可以增加数据逻辑处理层作为4层结构。在各层的外部添加启动服务application添加 @SpringBootConfiguration注解

src/main/resource---资源文件，主要包括public,static,templates(放html模板),resource，application.properties。springboot启动原理：通过注解映射查找application启动，然后依次扫描/META-INF/resources,/resources,/static,/public。一般模式将js,css放于static下，html放于templates下

注意：@RestController = @Controller + @ResponseBody，返回string或者json格式数据用@RestController

页面跳转用：@Controller

返回json,string格式数据用：@ResponseBody
