1. Run application
2. Open in browser: http://localhost:8080/
3. Read page :)

@Configuration
public class MvcConfig implements WebMvcConfigurer {
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/simple-mvc-config").setViewName("simple-mvc-config");
    }
}

See example:

• /src/main/java/examples/controller/extend/AbstractApiController.java
• /src/main/java/examples/controller/extend/CompanyController.java

the result of the company's route will be: /companies, not what we thought: /api/companies

See test: /src/test/java/examples/controller/extend/AbstractApiControllerTest.java
