スプリングブートで注釈を使用してビューリゾルバを設定する方法は？

Question

DispatcherServlet xmlファイルでビューリゾルバを設定しました。しかし、春の起動時に注釈を使ってビューリゾルバを設定するには？

Answer 1

Spring Boot documentationから：

If you want to keep Spring Boot MVC features, and you just want to add additional MVC configuration (interceptors, formatters, view controllers etc.) you can add your own @Configuration class of type WebMvcConfigurerAdapter, but without @EnableWebMvc. If you wish to provide custom instances of RequestMappingHandlerMapping, RequestMappingHandlerAdapter or ExceptionHandlerExceptionResolver you can declare a WebMvcRegistrationsAdapter instance providing such components.

If you want to take complete control of Spring MVC, you can add your own @Configuration annotated with @EnableWebMvc.

あなたはそれを行うことができます：もちろん

@Configuration 
public class WebConfig extends WebMvcConfigurerAdapter { 

    @Bean 
    public ViewResolver getViewResolver() { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix("/"); 
     resolver.setSuffix(".html"); 
     return resolver; 
    } 
} 

を、あなたの実際の構成に応じて接頭辞と接尾辞を適応させます。ルートフォルダ内にある

@Configuration 
public class WebConfig extends WebMvcConfigurerAdapter { 

    @Bean 
    public ViewResolver getViewResolver() { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix("/"); 
     resolver.setSuffix(".html"); 
     return resolver; 
    } 
    // add a mapping for redirection to index when/requested 
    @Override 
    public void addViewControllers(ViewControllerRegistry registry) { 
     registry.addViewController("/").setViewName("forward:/index"); 
    } 
}
