搭建spring3 的mvc开发-优快云博客

本文提供了一个使用Spring3 MVC框架开发RESTful服务的基本示例。通过web.xml配置和简单的控制器类实现，展示了如何处理HTTP GET请求并返回响应。

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。

< 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"

p:defaultEncoding ="utf-8" />

</ beans >

controller类

packagecom.mvc.rest;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importorg.springframework.stereotype.Controller;
importorg.springframework.ui.ModelMap;
importorg.springframework.web.bind.annotation.PathVariable;
importorg.springframework.web.bind.annotation.RequestMapping;
importorg.springframework.web.bind.annotation.RequestMethod;
importorg.springframework.web.servlet.ModelAndView;
@Controller
publicclassRestController{
publicRestController(){
}
@RequestMapping(value="/login/{user}",method=RequestMethod.GET)
publicModelAndViewmyMethod(HttpServletRequestrequest,HttpServletResponseresponse,
@PathVariable("user")Stringuser,ModelMapmodelMap)throwsException{
modelMap.put("loginUser",user);
returnnewModelAndView("/login/hello",modelMap);
}
@RequestMapping(value="/welcome",method=RequestMethod.GET)
publicStringregistPost(){
return"/welcome";
}
}

两个jsp页面
\WEB-INF\viewwelcome.jsp

< html >
< head >
< metahttp - equiv = " Content-Type " content = " text/html;charset=GBK " >
< title > Inserttitlehere </ 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
