SpringMVC3.0+rest小例子先看web.xml配置!-- 像js,css,gif等静态文件，需要配置为默认的servlet --servl

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 />              <!-- 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            p:prefix="/WEB-INF/view/" p:suffix=".jsp" />                 <bean id="multipartResolver"                       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;@Controllerpublic 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>
