我在使用spring-boot配置內容協商時遇到困難。我想保留大多數默認的spring-boot配置。我遵循了以下 https://spring.io/blog/2013/05/11/content-negotiation-using-spring-mvc/， 而不是最近的教程。目前，當我發送application/json或txt/html的請求時，視圖似乎沒有解決，但是當我打開視圖時，@EnableWebMvc它似乎得到了解決。以下是我當前的配置。@Configuration // according to the spring-boot docs this should be enough with spring-boot//@EnableWebMvc  If I enable this content-negotiation seems to work without any configuration, but I loose the default spring-boot configurationpublic class MvcConfiguration implements WebMvcConfigurer {    @Bean(name = "jsonViewResolver")    public ViewResolver getJsonViewResolver() {        return new JsonViewResolver();    }    @Override    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {    // Simple strategy: only path extension is taken into account        configurer.favorPathExtension(true)            .defaultContentType(MediaType.TEXT_HTML)            .mediaType("html", MediaType.TEXT_HTML)            .mediaType("json", MediaType.APPLICATION_JSON);}    @Bean    public ViewResolver contentNegotiatingViewResolver(ContentNegotiationManager manager) {        ContentNegotiatingViewResolver resolver = newContentNegotiatingViewResolver();        resolver.setContentNegotiationManager(manager);        return resolver;    }}
