SpringMVC环境简单搭建

本文介绍使用maven搭建Spring MVC

首先先介绍MVC（Model View Controller）模式：

Model（模型）：是应用程序中用于处理应用程序数据逻辑部分。通常模型对象负责在数据库中存取数据
View（视图）：是应用程序虫用于处理数据显示的部分。通常视图是依据数据模型创建的。
Controller（控制器）：是应用程序中处理用户交互的部分。通常控制器负责从视图中读取数据，控制用户输入，并向模型发送数据。

创建Spring MVC工程

使用创建Maven工程创建一个Web工程
为工程添加基本spring的依赖
添加spring的配置文件 applicationContext.xml，spring-mvc.xml
添加对应spring的属性文件
在web.xml中配置spring(要注意配置文件所放的路径)

applicationContext.xml

　　在applicationContext.xml中主要为：

启动注解: <context:component-scan base-package="***" />
加载属性文件：<context:property-placeholder location="" />
连接数据源
添加事务
配置错误页面

spring-mvc.xml：表示Controller返回的ModelAndView的基础上，加上目录前缀 /WEB-INF/webPage，加上文件后缀名.jsp，由此等待下个页面/WEB-INF/webPage/xxx.jsp。

100         <location>/WEB-INF/exception.jsp</location>
101     </error-page>
102 </web-app>

以上就基本将springmvc环境搭建完成了。

新建测试类：访问localhost:8080/xxx/index.html,来访问并跳转到pages/common下的index页面

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