SpringMVC3.0+rest小例子

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> 
<!-- url配置为/，不带文件后缀，会造成其它静态文件(js，css等)不能访问。如配为*.do，则不影响静态文件的

访问 --> 
 </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">  
          
       <!-- 自动扫描bean，把作了注解的类转换为bean -->  
      <context:component-scan base-package="com.mvc.rest" />  
    
       <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->  
      <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> 

 
     
       <!-- 对模型视图名称的解析，在请求时模型视图名称添加前后缀 -->  
       <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\view\welcome.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>
