如何在spring啓動時使用註釋配置視圖解析器？

Question

我已經在DispatcherServlet xml文件中配置了視圖解析器。但如何在spring啓動時使用註釋來配置視圖解析器？

從Spring Boot documentation：

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.

你可以這樣做：

@Configuration 
public class WebConfig extends WebMvcConfigurerAdapter { 

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

當然，適應前綴，並根據您的實際配置的後綴。

編輯處理重定向頁面時/是要求：

@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"); 
    } 
}
