# 静态首页可以放置的位置 #

可以将静态首页放在resources目录的public,static,resources目录。

# 关键源码（WebMvcAutoConfiguration） #

@Bean
    public WelcomePageHandlerMapping welcomePageHandlerMapping(ApplicationContext applicationContext,
          FormattingConversionService mvcConversionService, ResourceUrlProvider mvcResourceUrlProvider) {
       WelcomePageHandlerMapping welcomePageHandlerMapping = new WelcomePageHandlerMapping(
             new TemplateAvailabilityProviders(applicationContext), applicationContext, getWelcomePage(),
             this.mvcProperties.getStaticPathPattern());
       welcomePageHandlerMapping.setInterceptors(getInterceptors(mvcConversionService, mvcResourceUrlProvider));
       return welcomePageHandlerMapping;
    }
    
    
    private Optional<Resource> getWelcomePage() {
       String[] locations = getResourceLocations(this.resourceProperties.getStaticLocations());
       return Arrays.stream(locations).map(this::getIndexHtml).filter(this::isReadable).findFirst();
    }
    
    
    private Resource getIndexHtml(String location) {
       return this.resourceLoader.getResource(location + "index.html");
    }

# 首页标准放置位置 #

一般我们将首页放在template目录下，通过控制器访问，这时要引入

<dependency>
       <groupId>org.thymeleaf</groupId>
       <artifactId>thymeleaf</artifactId>
    </dependency>
