Когда я пытаюсь запустить приложение шлюза, я получаю следующую ошибку, которую я также попытался выполнить, изменив версию spring cloud на Hoxton.SR7, но он все еще не работает.
Пожалуйста, предоставьте решение для этого. Также я реализовал панель мониторинга hystrix, но застрял только на странице загрузки.
Ответ №1:
В соответствии с документами для Spring Cloud circuitBreaker GatewayFilter Factory
Чтобы включить фильтр Spring Cloud circuitBreaker, вам нужно либо поместить spring-cloud-starter-circuitbreaker-реактор-отказоустойчивость 4j, либо spring-cloud-starter-netflix-hystrix в путь к классу.
Итак, попробуйте после добавления приведенных ниже зависимостей в свой pom.xml файл :
- весна-облако-стартер-шлюз
- пружина-облако-стартер-прерыватель цепи-реактор-устойчивость 4j
- весна-облако-стартер-netflix-hystrix
Ответ №2:
В отличие от того, что в документах https://cloud.spring.io/spring-cloud-gateway/reference/html/#spring-cloud-circuitbreaker-filter-factory говорит о:
Чтобы включить фильтр Spring Cloud circuitBreaker, вам нужно либо поместить spring-cloud-starter-circuitbreaker-реактор-resilience4j, либо spring-cloud-starter-netflix-hystrix в путь к классу.
Нужно будет иметь ОБЕ зависимости, чтобы иметь автоматическую конфигурацию для настройки компонента SpringCloudCircuitBreakerResilience4JFilterFactory.
т. е. pom.xml:
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-circuitbreaker-reactor-resilience4j</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>
</dependencies>
Это связано с кодом этого класса автоматической настройки:
@ConditionalOnClass({ DispatcherHandler.class,
ReactiveResilience4JAutoConfiguration.class,
HystrixCircuitBreakerAutoConfiguration.class })
public class GatewayCircuitBreakerAutoConfiguration {
and @ConditionalOnClass's
javadocs говорит:
Классы, которые должны присутствовать.
Следовательно, все, что указано в качестве параметра списка для @ConditionalOnClass, находится в отношениях и вместо того, что утверждают документы или отношения.
Ответ №3:
Проверьте версию с пружинной загрузкой . У меня была та же проблема . Потратил много времени, чтобы найти решение. Проблема была решена при изменении версии spring-boot в файле .pom с версии 2.5.5 на версию 2.3.4 и версии spring-cloud.с 2020.0.4 на Hoxton.SR8
Ответ №4:
используйте эти версии:
parent version=2.4.3
spring-cloud version=2020.0.1
зависимости импорта:
spring-cloud-starter-circuitbreaker-reactor-resilience4j
jersey-apache-client4
Спасибо
