Spring boot doesn't map folder requests to `index.html` files

Question

I\'ve got static folder with following structure:

index.html
docs/index.html

Spring Boot correctly maps reque

Answer 1

After Java 8 introduced Default Methods in Interfaces, WebMvcConfigurerAdapter has been deprecated in Spring 5 / Spring Boot 2.

Using it will now raise the warning:

The type WebMvcConfigurerAdapter is deprecated

Hence, to make @hzpz's solution work again, we need to change it as follows:

@Configuration
public class CustomWebMvcConfigurer implements WebMvcConfigurer {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/docs").setViewName("redirect:/docs/");
        registry.addViewController("/docs/").setViewName("forward:/docs/index.html");
    }
}
