我认为您可以像这样注入自定义CorsProcessor：

import java.io.IOException;
    
    import org.springframework.boot.autoconfigure.web.servlet.WebMvcRegistrations;
    import org.springframework.http.server.ServerHttpResponse;
    import org.springframework.stereotype.Component;
    import org.springframework.web.cors.DefaultCorsProcessor;
    import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;
    
    @Component
    public class CustomWebMvcRegistrations implements WebMvcRegistrations {
        @Override
        public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
            RequestMappingHandlerMapping rhm = new RequestMappingHandlerMapping();
            rhm.setCorsProcessor(new DefaultCorsProcessor() {
                @Override
                protected void rejectRequest(ServerHttpResponse response) throws IOException {
                    // DO WHATEVER YOU WANT
                    super.rejectRequest(response);
                }
            });
            return rhm;
        }
    }
