3.SpringMVC介绍

1.采用Spring MVC的好处

Dispathcher Servlet必须做如下的事情：

1.根据URI调用相应的action

2.实例化正确的控制器类

3.根据请求参数值来构造表单bean

3.调用控制器对象的相应方法

4.转向到一个视图（JSP页面）

SpringMVC提供了Dispatcher Servlet

使用基于XML的配置文件，实例化控制器

自动绑定用户输入，正确转换数据类型

可以校验用户输入，支持国际化和本地化，

支持多种视图

2.SpringMVC的DispatcherServlet

相当于调度员Servlet

配置部署：

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="3.0"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
     <servlet>
         <servlet-name>springmvc</servlet-name>
         <servlet-class>
             org.springframework.web.servlet.DispatcherServlet
         </servlet-class>
         <load-on-startup>1</load-on-startup>
     </servlet>
 
     <servlet-mapping>
         <servlet-name>springmvc</servlet-name>
         <url-pattern> /</url-pattern>
     </servlet-mapping>
 
 </web-app>

load-on-startup 如存在，在程序启动时加载，
如不存在，在一个请求时候加载
 
springMVC的配置文件，可以放在WEB-INF下
也可以放在任何地方，用init-param加载该文件

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="3.0"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
     <servlet>
         <servlet-name>springmvc</servlet-name>
         <servlet-class>
             org.springframework.web.servlet.DispatcherServlet
         </servlet-class>
         <init-param>
             <param-name>contextConfigLocation</param-name>
             <param-value>/WEB-INF/config/springmvc-config.xml</param-value>
         </init-param>
         <load-on-startup>1</load-on-startup>
     </servlet>
 
     <servlet-mapping>
         <servlet-name>springmvc</servlet-name>
         <url-pattern>*.action</url-pattern>
     </servlet-mapping>
 </web-app>

3.Controller接口(传统风格控制器，要实现Controller接口)
2.5以前开发控制的唯一方法是org.springframework.web.servlet.mvc.Controller接口
只有一个方法handleRequest，而他的实现类只能处理一个单一动作Action
  ModelAndView handleRequest(HttpServletRequest request,HttpServletResponse response) 
而基于注解的控制器可以控制多个动作，无需实现任何接口
 
4.SpringMVC第一个应用
1.目录结构
spring-webmvc-x.y.z.jar包括了 DispatcherServlet

2.部署描述符文件和SpringMVC配置文件

2.1 部署文件

没有init-param，所以放在WEB-INF下

<url-pattern>/</url-pattern> 将所有的URL映射到该Servlet上

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="3.0"

5.测试应用

5.View Resolver

View Resolver负责配置视图解析器

 <?xml version="1.0" encoding="UTF-8"?>
 
 <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
 
     <bean name="/product_input.action" class="app03b.controller.InputProductController"/>
     <bean name="/product_save.action" class="app03b.controller.SaveProductController"/>
     <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <property name="prefix" value="/WEB-INF/jsp/"/>
         <property name="suffix" value=".jsp"/>
     </bean>
 </beans>

视图解析器配置了前缀和后缀两个属性：

view路径可以缩短，仅需提供myPage，无需在写/WEB-INF/jsp/myPage.jsp
