springmvc程序案例1

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 

  
  	springmvc
  	org.springframework.web.servlet.DispatcherServlet
 
  
  	contextConfigLocation
  	classpath:springmvc.xml
  
  
  
  
  	springmvc
  	*.do
  

4在springmvc.xml文件中配置处理器映射器

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

${hello}

7配置自定义UserController的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

9加载springmvc.xml

  
  	contextConfigLocation
  	classpath:springmvc.xml
  

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

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