springboot框架搭建

springboot新的開發模式：

1.jpa持久化規範，hibernate是具體的持久化實現。

2.orm對象關係映射，經過orm將內存中的數據持久化到數據庫或者磁盤中永久保存。

3.jsp配置注意事項，需創建war項目，同時引入servlet,jstl,tomcat配置等，配置springMVC前綴，後綴，編寫control。不建議使用jsp。

4.推薦使用thymelefe模板引擎技術事項jsp的功能，自帶相似於jstl標籤的功能。

5.文件夾解析：src/main/java/---java代碼包括，entity,dao,service,controller基本的3層結構，另外能夠增長數據邏輯處理層做爲4層結構。在各層的外部添加啓動服務application添加 @SpringBootConfiguration註解

src/main/resource---資源文件，主要包括public,static,templates(放html模板),resource，application.properties。springboot啓動原理：經過註解映射查找application啓動，而後依次掃描/META-INF/resources,/resources,/static,/public。通常模式將js,css放於static下，html放於templates下

注意：@RestController = @Controller + @ResponseBody，返回string或者json格式數據用@RestController

頁面跳轉用：@Controller

返回json,string格式數據用：@ResponseBody
