您可以像a fixed issue提到的那样使用.andThen(secondDecorator)

protected <T> Function<Publisher<T>, Publisher<T>> decorateWithCircuitBreakerForSpecificEndpoint() {
    final CircuitBreakerConfig circuitBreakerConfig = CircuitBreakerConfig.custom()
        .failureRateThreshold(100)
        .recordFailure(throwable -> throwable instanceof RuntimeException)
        .ringBufferSizeInClosedState(10)
        .ringBufferSizeInHalfOpenState(10)
        .waitDurationInOpenState(Duration.ofSeconds(5_000))
        .build();
    final CircuitBreaker circuitBreaker = this.circuitBreakerRegistry.circuitBreaker("test1", circuitBreakerConfig);
    return CircuitBreakerOperator.<T>of(circuitBreaker).andThen(decorateWithCircuitBreakerForSpecificHost());
}

protected <T> Function<Publisher<T>, Publisher<T>> decorateWithCircuitBreakerForSpecificHost() {
    final CircuitBreakerConfig circuitBreakerConfig = CircuitBreakerConfig.custom()
        .failureRateThreshold(10)
        .recordFailure(throwable -> throwable instanceof RuntimeException)
        .ringBufferSizeInClosedState(5)
        .ringBufferSizeInHalfOpenState(5)
        .waitDurationInOpenState(Duration.ofSeconds(5_000))
        .build();
    final CircuitBreaker circuitBreaker = this.circuitBreakerRegistry.circuitBreaker("test2", circuitBreakerConfig);
    return CircuitBreakerOperator.<T>of(circuitBreaker);
}
