How to specify mime-mapping using servlet 3.0 java config?

Question

I am using Servlet 3.0 and looking to convert my existing web.xml file to java config. Configuring servlets/filters etc seems to be pretty straight away. I can't figure out how to convert the following mime-mapping. Can anyone help me out?

<mime-mapping>
    <extension>xsd</extension>
    <mime-type>text/xml</mime-type>
</mime-mapping>

I faced this problem in a Spring Boot application. My solution was to create a class that implements org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer as following:

@Configuration
public class MyMimeMapper implements EmbeddedServletContainerCustomizer {
  @Override
  public void customize(ConfigurableEmbeddedServletContainer container) {
    MimeMappings mappings = new MimeMappings(MimeMappings.DEFAULT);
    mappings.add("xsd", "text/xml; charset=utf-8");
    container.setMimeMappings(mappings);
  }
}
