我正在尝试使用spring.boot version: 2.1.5.RELEASE和Kafka version: 2.0.1启动新项目，但遇到了无法通过SSL连接到我的kafka远程代理的问题。
与此同时，我的带有spring.boot version: 2.0.1.RELEASE和Kafka version: 1.0.1的旧项目运行正常。
application.yml
spring:
cloud:
stream:

binder:

autoCreateTopics: false

trust-store-password: 123456
key-password: 123456
key-store-location: guest.keystore
key-store-password: 123456
收到这样的错误消息：
2019-06-10 17:59:03.636 ERROR 30220 --- [ main] o.s.c.s.b.k.p.KafkaTopicProvisioner : Failed to obtain partition information
org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after 60000 ms.
旧项目属性（一切正常）
spring.kafka.bootstrap-servers=my-kafka:9093
spring.kafka.consumer.properties.[group.id]=group_23_spring-kafka
# SSL
spring.kafka.properties.[security.protocol]=SSL
spring.kafka.ssl.trust-store-location=guest.truststore
spring.kafka.ssl.trust-store-password=123456
spring.kafka.ssl.key-store-password=123456
spring.kafka.ssl.key-store-location=guest.keystore
spring.kafka.ssl.key-password=123456
如果我用
更新我的工作项目， <dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>2.0.1</version>
</dependency>
它会产生相同的错误

我也在question的github上问了同样的spring-cloud-stream-binder-kafka，但我们没有找到结论
有人遇到过同样的问题吗？或者，也许知道我必须如何配置application.yml才能通过SSL连接到我的kafka代理？
谢谢
