我已经在 DispatcherServlet xml 文件中配置了 View 解析器。但是如何在 Spring Boot 中使用注解配置 View 解析器呢？

来自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.

你能做到:

@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

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

当然，根据您的实际配置调整前缀和后缀。

编辑以在请求 / 时处理到页面的重定向:

@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");
    }
}
