spring mobile 是spring新推出的一个用于支持移动浏览的小框架，用起来很简单，和spring mvc结合也很方便。
首先建立一个spring mvc的工程
然后，在pom.xml中添加spring mobile的支持
<dependency>
<groupId>org.springframework.mobile</groupId>
<artifactId>spring-mobile-device</artifactId>
<version>1.1.0.RELEASE</version>
</dependency>
修改servlet-content.xml
<!-- Enables the Spring MVC @Controller programming model -->
<annotation-driven>
<argument-resolvers>
<beans:bean
class="org.springframework.mobile.device.DeviceWebArgumentResolver" />
<beans:bean
class="org.springframework.mobile.device.site.SitePreferenceWebArgumentResolver" />
</argument-resolvers>
</annotation-driven>
<interceptors>
<!-- On pre-handle, resolve the device that originated the web request -->
<beans:bean
class="org.springframework.mobile.device.DeviceResolverHandlerInterceptor" />
<!-- On pre-handle, manage the user's site preference (declare after DeviceResolverHandlerInterceptor) -->
<beans:bean
class="org.springframework.mobile.device.site.SitePreferenceHandlerInterceptor" />
</interceptors>
<!-- Handles HTTP GET requests for /resources/** by efficiently serving
up static resources in the ${webappRoot}/resources directory -->
<resources mapping="/resources/**" location="/resources/" />
<!-- Resolves views selected for rendering by @Controllers to .jsp resources
in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.mobile.device.view.LiteDeviceDelegatingViewResolver">
<beans:constructor-arg>
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
</beans:constructor-arg>
<beans:property name="enableFallback" value="true" />
<beans:property name="mobilePrefix" value="mobile/" />
<beans:property name="tabletPrefix" value="tablet/" />
</beans:bean>
然后在views目录下，新增两个目录：mobile和tablet。拷贝home.jsp页面进去。
为了区分，分别修改3个home.jsp，如下
home.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
<title>Home</title>
</head>
<body>
<h1>
Hello world!
</h1>
<P> This is normal. </P>
<P> The time on the server is ${serverTime}. </P>
</body>
</html>
moblie/home.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
<title>Home</title>
</head>
<body>
<h1>
Hello world!
</h1>
<P> This is mobile. </P>
<P> The time on the server is ${serverTime}. </P>
</body>
</html>
tablet/home.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
<title>Home</title>
</head>
<body>
<h1>
Hello world!
</h1>
<P> This is tablet. </P>
<P> The time on the server is ${serverTime}. </P>
</body>
</html>
这样就完成了，容易吧。
当检测到时手机访问的时候，会自动将view映射到moblie目录下，当检测到平板访问的时候会将view映射到tablet目录下，其他时候，映射到根目录下。
这是电脑访问的样子
这是手机访问的样子
很方便呢。spring mobile还提供了其他的几种方式，在官网有个例子的链接，很直观。https://github.com/spring-projects/spring-mobile-samples
