Answer 1

Previous answer is for tomcat only, so adding mine as well. You can disable the method cross-container by, for example, using a standard servlet filter:

import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

import org.springframework.stereotype.Component;     
import org.springframework.web.filter.OncePerRequestFilter; 

@Component
public class MethodFilter extends OncePerRequestFilter { 

    @Override 
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) 
                    throws ServletException, IOException { 
        if (request.getMethod().equals("OPTIONS")) {
            response.sendError(HttpServletResponse.SC_METHOD_NOT_ALLOWED);
        } else { 
            filterChain.doFilter(request, response); 
        } 
    }
} 

Note: it is assumed that this class is componentscanned by Spring. If not, you can use other registration methods as detailed in here.

Answer 2

Try this; in allowedMethods you can filter methods which are required:

@Configuration
public class CorsConfiguration {

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**")
                        .allowedOrigins(origins u want to allow)
                        .allowCredentials(false).allowedMethods("POST", "GET", "PUT");

            }
        };
    }
}

I tried this and it worked.

@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
    return new EmbeddedServletContainerCustomizer() {
        @Override
        public void customize(ConfigurableEmbeddedServletContainer container) {
            if (container.getClass().isAssignableFrom(TomcatEmbeddedServletContainerFactory.class)) {
                TomcatEmbeddedServletContainerFactory tomcatContainer = (TomcatEmbeddedServletContainerFactory) container;
                tomcatContainer.addContextCustomizers(new ContextSecurityCustomizer());
            }
        }
    };
}

private static class ContextSecurityCustomizer implements TomcatContextCustomizer {
    @Override
    public void customize(Context context) {
        SecurityConstraint constraint = new SecurityConstraint();
        SecurityCollection securityCollection = new SecurityCollection();
        securityCollection.setName("restricted_methods");
        securityCollection.addPattern("/*");
        securityCollection.addMethod(HttpMethod.OPTIONS.toString());
        constraint.addCollection(securityCollection);
        constraint.setAuthConstraint(true);
        context.addConstraint(constraint);
    }
}
