Spring Mobile 2.0.0 M3

Spring Mobile是一个框架，它提供了检测向Spring web站点发出请求的设备类型的功能，并提供基于该设备的其他视图。像所有的Spring项目一样，Spring Mobile的真正威力在于它的可扩展性。
特征
一种用于移动和平板设备服务器端检测的设备解析器抽象
站点首选项管理，允许用户指示他/她是否喜欢“正常”、“移动”或“平板”体验
一种站点切换器，能够根据用户的设备和可选的指定站点偏好，将用户切换到最合适的站点（移动、平板电脑或普通站点）
用于组织和管理特定设备的不同视图的设备感知视图管理

Spring Mobile is a framework that provides capabilities to detect the type of device making a request to your Spring web site and serve alternative views based on that device. Like all Spring projects, the real power of Spring Mobile is found in how easily it can be extended.

Features

A Device resolver abstraction for server-side detection of mobile and tablet devices

Site preference management that allows the user to indicate if he or she prefers a “normal”, “mobile”, or “tablet” experience

A site switcher capable of switching the user to the most appropriate site, either mobile, tablet, or normal, based on his or her device and optionally indicated site preference

Device aware view management for organizing and managing different views for specific devices

Spring Boot Config

To use Spring Mobile, add the following dependency to your application
Maven

org.springframework.mobile spring-mobile-device 2.0.0.M3 spring-milestones Spring Milestones https://repo.spring.io/libs-milestone false

Gradle

dependencies {
compile ‘org.springframework.mobile:spring-mobile-device:2.0.0.M3’
}repositories {
maven {
url ‘https://repo.spring.io/libs-milestone’
}
}

Device detection

Add the following Java-based configuration to enable device detection in a Spring web application:

@Bean
public DeviceResolverHandlerInterceptor
deviceResolverHandlerInterceptor() {
return new DeviceResolverHandlerInterceptor();
}

@Bean
public DeviceHandlerMethodArgumentResolver
deviceHandlerMethodArgumentResolver() {
return new DeviceHandlerMethodArgumentResolver();
}

@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(deviceResolverHandlerInterceptor());
}

@Override
public void addArgumentResolvers(
List argumentResolvers) {
argumentResolvers.add(deviceHandlerMethodArgumentResolver());
}

Inject the Device into your controller:

@Controller
public class HomeController {

private static final Logger logger =
        LoggerFactory.getLogger(HomeController.class);

@RequestMapping("/")
public void home(Device device) {
    if (device.isMobile()) {
        logger.info("Hello mobile user!");
    } else if (device.isTablet()) {
        logger.info("Hello tablet user!");
    } else {
        logger.info("Hello desktop user!");
    }
}

}

Site preference

Add the following Java-based configuration to enable site preference management in a Spring web application:

@Bean
public DeviceResolverHandlerInterceptor
deviceResolverHandlerInterceptor() {
return new DeviceResolverHandlerInterceptor();
}

@Bean
public SitePreferenceHandlerInterceptor
sitePreferenceHandlerInterceptor() {
return new SitePreferenceHandlerInterceptor();
}

@Bean
public SitePreferenceHandlerMethodArgumentResolver
sitePreferenceHandlerMethodArgumentResolver() {
return new SitePreferenceHandlerMethodArgumentResolver();
}

@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(deviceResolverHandlerInterceptor());
registry.addInterceptor(sitePreferenceHandlerInterceptor());
}
@Override
public void addArgumentResolvers(
List argumentResolvers) {
argumentResolvers.add(sitePreferenceHandlerMethodArgumentResolver());
}

Inject the SitePreference into your controller:

@Controller
public class HomeController {

private static final Logger logger =
        LoggerFactory.getLogger(HomeController.class);

@RequestMapping("/")
public String home(SitePreference sitePreference, Model model) {
    if (sitePreference == SitePreference.NORMAL) {
        logger.info("Site preference is normal");
        return "home";
    } else if (sitePreference == SitePreference.MOBILE) {
        logger.info("Site preference is mobile");
        return "home-mobile";
    } else if (sitePreference == SitePreference.TABLET) {
        logger.info("Site preference is tablet");
        return "home-tablet";
    } else {
        logger.info("no site preference");
        return "home";
    }
}

}

Device aware view resolution

Add the following Java-based configuration to enable device aware views in a Spring web application. This specifies that Spring Mobile will look for mobile views in /WEB-INF/views/mobile/ and tablet views in /WEB-INF/views/tablet/.

@Bean
public LiteDeviceDelegatingViewResolver liteDeviceAwareViewResolver() {
InternalResourceViewResolver delegate =
new InternalResourceViewResolver();
delegate.setPrefix("/WEB-INF/views/");
delegate.setSuffix(".jsp");
LiteDeviceDelegatingViewResolver resolver =
new LiteDeviceDelegatingViewResolver(delegate);
resolver.setMobilePrefix(“mobile/”);
resolver.setTabletPrefix(“tablet/”);
return resolver;
}
