spring3.0 mvc和rest入门例子

关键字：spring3.0 mvc和rest入门例子

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
