与文档https://cloud.spring.io/spring-cloud-gateway/reference/html/#spring-cloud-Circuitbreaker-filter-factory所说的不同：

要启用 Spring Cloud CircuitBreaker 过滤器，您需要将spring-cloud-starter-Circuitbreaker-reactor-resilience4j 或 spring-cloud-starter-netflix-hystrix放在类路径上。

需要同时拥有这两个依赖项才能进行自动配置来配置 SpringCloudCircuitBreakerResilience4JFilterFactory bean。

IE。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>

这是由于这个自动配置类的代码：

@ConditionalOnClass({ DispatcherHandler.class,
        ReactiveResilience4JAutoConfiguration.class,
        HystrixCircuitBreakerAutoConfiguration.class })
public class GatewayCircuitBreakerAutoConfiguration {
and @ConditionalOnClass's

javadoc 说：

必须存在的类。

因此，无论列出为 @ConditionalOnClass 的列表参数，都属于 和 关系，而不是文档声称的或 关系。

根据Spring Cloud CircuitBreaker GatewayFilter Factory的文档

要启用 Spring Cloud CircuitBreaker 过滤器，您需要将 spring-cloud-starter-Circuitbreaker-reactor-resilience4j 或 spring-cloud-starter-netflix-hystrix 放在类路径上。

因此，在文件中添加以下依赖项后尝试pom.xml：

  1. spring-cloud-starter-网关
  2. spring-cloud-starter-Circuitbreaker-reactor-resilience4j
  3. spring-cloud-starter-netflix-hystrix
