spring3.0 mvc和rest风格小例子

之前在新一个项目中用了spring3 的mvc开发，用得很爽，不过当时想找些入门的小例子时，找了好久也没找到，

现在写个简单的小例子出来给初学者学习下。
srping3也支持rest，所以例子也包括这部分内容。
先看web.xml配置

< servlet-mapping >
      < servlet-name > default </ servlet-name >
      < url-pattern > *.js </ url-pattern >
</ servlet-mapping >
    < servlet-mapping >
      < servlet-name > default </ servlet-name >
      < url-pattern > *.css </ url-pattern >
</ servlet-mapping >

< servlet >
      < servlet-name > spring </ servlet-name >
      < servlet-class > org.springframework.web.servlet.DispatcherServlet </ servlet-class >
      < load-on-startup > 1 </ load-on-startup >
</ servlet >
< servlet-mapping >
      < servlet-name > spring </ servlet-name >
      < url-pattern > / </ url-pattern >

</ servlet-mapping >

spring-servlet.xml文件配置，注：XXXX-servlet.xml的XXXX就是上边<servlet-name>spring</servlet-name>中

的名称，如果上边为<servlet-name>mvc</servlet-name>则这个文件名为mvc-servelt.xml。

< beans xmlns ="http://www.springframework.org/schema/beans"
       xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"

xmlns:p ="http://www.springframework.org/schema/p"
        xmlns:context ="http://www.springframework.org/schema/context"
        xsi:schemaLocation ="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.0.xsd" >

        
       < context:component-scan base-package ="com.mvc.rest" />

        
       < bean class ="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />


        
        < bean class ="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix ="/WEB-INF/view/" p:suffix =".jsp" />

        < bean id ="multipartResolver"
          class ="org.springframework.web.multipart.commons.CommonsMultipartResolver"
          p:defaultEncoding ="utf-8" />

   </ beans >

controller类

package com.mvc.rest;

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

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class RestController

{

public RestController()

{

    }

    @RequestMapping(value = "/login/{user}", method = RequestMethod.GET)
    public ModelAndView myMethod(HttpServletRequest request, HttpServletResponse response,
            @PathVariable("user") String user, ModelMap modelMap) throws Exception

{
        modelMap.put("loginUser", user);
        return new ModelAndView("/login/hello", modelMap);
    }

     @RequestMapping(value = "/welcome", method = RequestMethod.GET)
        public String registPost()

{
         return "/welcome";
        }
}

两个jsp页面
\WEB-INF\viewwelcome.jsp

< html >
< head >
< meta http - equiv = " Content-Type " content = " text/html; charset=GBK " >
< title > Insert title here </ title >
</ head >
< body >
欢迎
</ body >
</ html >

\WEB-INF\view\login\hello.jsp
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<title>Insert title here</title>
</head>
<body>
你好:<%=request.getAttribute("loginUser") %>
</body>
</html>

运行效果
访问http://localhost:8089/mvc/welcome

访问http://localhost:8089/mvc/login/pengo
