本文介紹使用maven搭建Spring MVC

首先先介紹MVC（Model View Controller）模式：

Model（模型）：是應用程序中用于處理應用程序數據邏輯部分。通常模型對象負責在數據庫中存取數據

View（視圖）：是應用程序蟲用于處理數據顯示的部分。通常視圖是依據數據模型創建的。

Controller（控制器）：是應用程序中處理用戶交互的部分。通?？刂破髫撠煆囊晥D中讀取數據，控制用戶輸入，并向模型發送數據。

創建Spring MVC工程

使用創建Maven工程創建一個Web工程

為工程添加基本spring的依賴

添加spring的配置文件 applicationContext.xml，spring-mvc.xml

添加對應spring的屬性文件

在web.xml中配置spring(要注意配置文件所放的路徑)

applicationContext.xml??

　　在applicationContext.xml中主要為：

• 啟動注解: <context:component-scan base-package="***" ?/>
• 加載屬性文件：<context:property-placeholder location="" />
• 連接數據源
• 添加事務
• 配置錯誤頁面

spring-mvc.xml：表示Controller返回的ModelAndView的基礎上，加上目錄前綴 /WEB-INF/webPage，加上文件后綴名.jsp，由此等待下個頁面/WEB-INF/webPage/xxx.jsp。

以上就基本將springmvc環境搭建完成了。

新建測試類：訪問localhost:8080/xxx/index.html,來訪問并跳轉到pages/common下的index頁面

1 @Controller 2 public class IndexController { 3 4 @RequestMapping("/index") 5 public String index(HttpServletRequest request) { 6 return "pages/common/index"; 7 } 8 9 }
