在SpringBoot2.3.3上试用netflix hystrix时，出现以下错误-。。。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'freeMarkerConfigurer' defined in org.springframework.cloud.netflix.hystrix.dashboard.HystrixDashboardConfiguration: Invocation of init method failed; nested exception is java.lang.NoSuchFieldError: DEFAULT_INCOMPATIBLE_IMPROVEMENTS

main simpleclientapplication.java有以下注解

@SpringBootApplication
@EnableCircuitBreaker
@EnableHystrixDashboard

productlistcontroller.java。。。

@RestController
@EnableAutoConfiguration(exclude = { FreeMarkerAutoConfiguration.class })
public class ProductListController {

    @GetMapping
    @HystrixCommand(fallbackMethod = "defaultProducts")
    public List<String> cloudProductList() {

        RestTemplate restTemplate = new RestTemplate();
        URI uri = URI.create("http://localhost:8090/products");

        return restTemplate.getForObject(uri, List.class);
    }

    public List<String> defaultProducts() {
        return Arrays.asList("Spring Cloud");
    }
}

pom.xml。。。
