SpringMVC+Spring+HIbernate 簡單增刪改查例項

SpringMVC+Spring+HIbernate 簡單增刪改查例項
HIbernate配置mysql資料庫的方式 和 Structs+spring+HIbernate 是一樣的。
可以理解為SpringMVC 把 Structs2 替代了，SpringMVC 中的 Controller 對應 Structs2 中的 Action，相對來說更加的簡單，畢竟少了一個配置檔案struts.xml，這個例項中連xx.hbm.xml都用註解的方式代替了
對應頁面回顯資料，Struts2中，用值棧、session、Request等，SpringMVC中也可以使用Servlet API，session等都可以用，可以用 Map、Model等來回顯資料
頁面上可以使用JSTL，Struts的 s標籤就沒了
<s:iterator value="list" var="d">
- 1
<c:forEach var="p" items="${requestScope.personlist }">
- 1
刪除和修改都是url中傳入id的引數

專案結構
除了spring和HIbernate基本包還需要加 jstl標籤庫的jar包
jstl.jar standard.jarHIbernate c3p0 jar包，
c3p0-0.9.2.1.jar hibernate-c3p0-4.3.11.Final.jar mchange-commons-java-0.2.3.4.jar 3個
對應在hibernate-release-4.3.11.Final\lib\optional\c3p0目錄下mysql資料庫連線的jar包
mysql-connector-java-5.1.40-bin.jarjar包在原始碼裡有
沒有使用各層的介面
