springmvc学习笔记（一）第一个helloworld

1.新建web工程，导入spring包和common-loggin.jar包；配置web.xml

      
        springMVC  
        org.springframework.web.servlet.DispatcherServlet  
        1  
      
      
        springMVC  
        /  
      

2.编写Controller类，相当于struts2中的Action

public class HelloWorldController implements Controller{

	public ModelAndView handleRequest(HttpServletRequest arg0,
			HttpServletResponse arg1) throws Exception {
		System.out.println("8888888888888888888");
		return new ModelAndView("welcome");
	}

}

返回结果是以welcome为参数的，意思是跳转到welcome.jsp显示视图．

3.配置"servletName"-servlet.xml

-servlet.xml文件名称默认根据web.xml中配置的DispacherServlet的servlet名称，加上-servlet.xml而来的．

所以当前的配置文件名称为 springMVC-servlet.xml.

id为/test1/helloWorld的bean的类对应上面的controller.

4.视图jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>



  
    
    
  
  
  
    欢迎大家来学习springmvc

  

5.测试．

浏览器中输入controller的id

http://localhost:8080/springMVC/test1/helloWorld
