我已经手动配置并解决了此问题
添加以下基于Java的配置以在Spring Web应用程序中启用设备检测：
@Beanpublic DeviceResolverhandlerinterceptor deviceResolverhandlerinterceptor() { return new DeviceResolverhandlerinterceptor();}@Beanpublic DeviceHandlerMethodArgumentResolver deviceHandlerMethodArgumentResolver() { return new DeviceHandlerMethodArgumentResolver();}@Overridepublic void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(deviceResolverhandlerinterceptor());}@Overridepublic void addArgumentResolvers( List<HandlerMethodArgumentResolver> argumentResolvers) { argumentResolvers.add(deviceHandlerMethodArgumentResolver());}
将 设备 注入控制器
@Controllerpublic 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!'); }}}
http://projects.spring.io/spring-mobile/
正如@erhanasikoglu所指出的；
由于不赞成使用WebMvcConfigurerAdapter，因此只需要在该配置类内实现WebMvcConfigurer接口。（https://docs.spring.io/spring/docs/current/javadoc-apI/Org/springframework/web/servlet/config/annotation/WebMvcConfigurerAdapter.html）
解决方法最近我尝试将Spring Boot应用程序版本从1.5.10.RELEASE更新到2.0.0.RELEASE
项目环境
JDK版本1.8 Gradle中的jcenter（）存储库 IDE弹簧工具套件（STS）版本：3.9.2我遇到了两个问题
我在下面遇到了完成问题。无法解析配置’：compileClasspath’的所有文件。找不到org.springframework.boot：spring-boot-starter-mobile：
然后我检查了最新版本的spring-boot-starter-mobile库，并且没有用于Spring Boot 2的稳定版本的spring-boot-starter-mobile。
因此，我必须使用maven声明里程碑URL来导入版本：“ 2.0.0.M5”，问题已解决。
专家{url’https: //repo.spring.io/milestone‘}
最初我使用的是jcenter（），是否可以使用jcenter导入里程碑？
访问下面的移动设备界面时，出现以下运行时错误。org.springframework.mobile.device.Device
public ResponseEntity<?> TestM(@RequestBody MyRequest myRequest,Device device) throws AuthenticationException { return ResponseEntity.ok();}
错误
