1创建一个web工程


2导入springmvc的jar文件


3在web.xml中配置前端控制器 

  <servlet>
  	<servlet-name>springmvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 
  <init-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:springmvc.xml</param-value>
  </init-param>
  
  </servlet>
  <servlet-mapping>
  	<servlet-name>springmvc</servlet-name>
  	<url-pattern>*.do</url-pattern>
  </servlet-mapping>


4在springmvc.xml文件中配置处理器映射器

<!-- 配置处理器映射器 -:根据自定义Bean的name属性的url去寻找执行类->
 <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>


5配置处理器适配器

<!-- 配置处理器适配器 负责执行UserController -->
<bean  class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>


6自定义类UserController

package cn.itcast.controller;

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

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

public class UserController implements Controller{

	@Override
	public ModelAndView handleRequest(HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		ModelAndView mvAndView = new ModelAndView() ;
		mvAndView.addObject("hello", "I love too");
		//
		//mvAndView.setViewName("/WEB-INF/jsps/index.jsp");
		mvAndView.setViewName("index");
		return mvAndView;
	}	
}



创建的页面

<body>
<h1>${hello}</h1>
</body>



7配置自定义UserController的bean

<!-- 配置自定义bean 这个name属性值就是url访问地址-->
                           
  <bean name="/hello.do" class="cn.itcast.controller.UserController"></bean>


8配置视图解析器:

如果controller使用逻辑视图,必须配置视图解析器
 <!-- 配置视图解析器 -->
     <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
     <property name="prefix" value="/WEB-INF/jsps/"></property>
	<property name="suffix" value=".jsp"></property></bean>


9加载springmvc.xml

  <init-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:springmvc.xml</param-value>
  </init-param>


10访问 项目名+自定义controller的Bean的name属性的url

http://localhost:8080/springmvc1/hello.do
