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
<!-- 像js,css,gif等静态文件，需要配置为默认的servlet -->
<
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。

<!--
自动扫描bean，把作了注解的类转换为bean

</

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
