thymeleaf主页定制

@Configuration
public class MyMvcConfig implements WebMvcConfigurer {
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("index");
        registry.addViewController("/index.html").setViewName("index");
    }
}

注意点:

1. 所有页面的静态资源都需要使用thymeleaf接管
2. url: @{}
