如何在spring启动时使用注释配置视图解析器？

Question

我已经在DispatcherServlet xml文件中配置了视图解析器。但如何在spring启动时使用注释来配置视图解析器？

Answer 1

从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.

你可以这样做：

@Configuration 
public class WebConfig extends WebMvcConfigurerAdapter { 

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

当然，适应前缀，并根据您的实际配置的后缀。

编辑处理重定向页面时/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"); 
    } 
}
