搭建SpringMVC项目

创建WEB项目

构建转发器 - DispatcherServlet

<!-- 在web.xml文件中 -->
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

<!-- 配制springMVC 的 DispatcherServlet -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>

构建请求和处理的映射关系 - HandlerMapping

构建控制器 - Controller

构建视图解析器 - ViewResolver

<!-- 2、handlerMapping 默认情况下 bean的name属性是默认的映射处理器，不需要特殊配置 -->
<!-- 3、controller -->
<bean id="myController" name="/defaultHandlerMapping.do" class="com.wowSpark.springmvc.MyController"></bean>

<!-- 4、ViewResolver  视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>

编写Controller对应的类

package com.wowSpark.springmvc;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class MyController extends AbstractController {

@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
return new ModelAndView("welcome");
}

}
