@Bean public WelcomePageHandlerMapping welcomePageHandlerMapping(ApplicationContext applicationContext, FormattingConversionService mvcConversionService, ResourceUrlProvider mvcResourceUrlProvider) { WelcomePageHandlerMapping welcomePageHandlerMapping = new WelcomePageHandlerMapping( new TemplateAvailabilityProviders(applicationContext), applicationContext, getWelcomePage(), // getWelcomePage 获得欢迎页 this.mvcProperties.getStaticPathPattern()); welcomePageHandlerMapping.setInterceptors(getInterceptors(mvcConversionService, mvcResourceUrlProvider)); return welcomePageHandlerMapping; }
点进去继续看
private Resource getWelcomePage() { for (String location : this.resourceProperties.getStaticLocations()) { Resource indexHtml = getIndexHtml(location); if (indexHtml != null) { return indexHtml; } } ServletContext servletContext = getServletContext(); if (servletContext != null) { return getIndexHtml(new ServletContextResource(servletContext, SERVLET_LOCATION)); } return null; } private Resource getIndexHtml(String location) { return getIndexHtml(this.resourceLoader.getResource(location)); }
静态资源文件夹下的所有 index.html 页面;被 /** 映射。
比如我访问 http://localhost:8080/ ,就会找静态资源文件夹下的 index.html
新建一个 index.html ,在下面的3个目录中任意一个;然后访问测试 http://localhost:8080/ 看结果!
