elementary helloworld. Please help me for the second day I'm trying (

It starts index, but when you click on the link it doesn't see the controller, it

gives out

The requested resource [/amount] is not available

Restarted it again. And the whole project too. Didn't help

context root in app settings = /

on server:

package java.bit.config;
 
 
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
 
public class MySpringMvcDispatcherServletInitializer  extends AbstractAnnotationConfigDispatcherServletInitializer{
 
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }
 
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] {SpringConfig.class};
    }
    
    @Override
    protected String[] getServletMappings() {
        return new String[] {"/"};
    }
 
}

        SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
        templateResolver.setApplicationContext(applicationContext);
        templateResolver.setPrefix("/WEB-INF/views/");
        templateResolver.setSuffix(".jsp");
        return templateResolver;
    }
 
    @Bean

        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());
        templateEngine.setEnableSpringELCompiler(true);
        return templateEngine;
    }
    
    @Override

        resolver.setTemplateEngine(templateEngine());
        registry.viewResolver(resolver);
