Answer 1

See my answer: https://stackoverflow.com/a/15551678/173149 or just:

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
    <url-pattern>/index.htm</url-pattern>    <<==  *1*
</servlet-mapping>
<welcome-file-list>
    <welcome-file>index.htm</welcome-file>   <<== *2*
</welcome-file-list>

Answer 2

In case of java configuration you can override two methods in class that extends WebMvcConfigurerAdapter

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("/index");
}

@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
    configurer.enable();
}

If you wanna serve index.html explicitly, turn it into a resource override a method in the same class as below:

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/index.html").addResourceLocations("/WEB-INF/views/index.html");
}

Of course addResourceLocations must follows the folder choosen to hold your views.

Answer 3

@RequestMapping({"/index", "/"})

and

<welcome-file-list>
    <welcome-file></welcome-file>
</welcome-file-list>

worked for me.

Answer 4

Try using

<welcome-file-list>
  <welcome-file>/index</welcome-file>
</welcome-file-list>
