@RestCont         


        

Answer 1

In SpringBoot Application In order to enable Matrix variables you need to define below override code

@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configurePathMatch(PathMatchConfigurer configurer) {
        UrlPathHelper urlPathHelper = new UrlPathHelper();
        urlPathHelper.setRemoveSemicolonContent(false);
        configurer.setUrlPathHelper(urlPathHelper);
    }
}

Otherwise, they’re disabled by default

Answer 2

As the documentation you linked to states,

Note that to enable the use of matrix variables, you must set the removeSemicolonContent property of RequestMappingHandlerMapping to false. By default it is set to true with the exception of the MVC namespace and the MVC Java config both of which automatically enable the use of matrix variables.

If you're configuring your application by extending WebMvcConfigurationSupport, then override the requestMappingHandlerMapping method which prepares the RequestMappingHandlerMapping and set its appropriate property.

@Override
public RequestMappingHandlerMapping requestMappingHandlerMapping() {
    final RequestMappingHandlerMapping requestMappingHandlerMapping = super.requestMappingHandlerMapping();
    requestMappingHandlerMapping.setRemoveSemicolonContent(false); // <<< this
    return requestMappingHandlerMapping;
}

You'll then be all set.

With Spring Boot, I think all you need is to declare a @Bean method with the above, ie. that returns a RequestMappingHandlerMapping instance.
