Spring Boot 2NoSuchMethodException：org.springframework.mobile.device.Device。（）

我已经手动配置并解决了此问题

设备检测

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!");  }}}

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
