我正在测试sample code of Spring Kafka。它适用于PLAINTEXT连接，但不适用于SSL连接。
我已通过成功运行控制台消费者验证了密钥和证书对kafka代理有效：
bin/kafka-console-consumer.sh --bootstrap-server xx.xx.xx.xx:50070
--topic myTopic --consumer.config client-ssl.properties --from-beginning
但我不能使用Spring Kafka使用Spring Boot（2.0.1.RELEASE）发送消息，使用相同的密钥和证书。

有没有人使用SSL成功配置Spring Boot 2.0 + Spring Kafka？
答案 0 :(得分：2)
ssl.keystore.location = null
ssl.keystore.password = null
您只为消费者配置SSL ...
spring.kafka.consumer.ssl.keystore-location=classpath:client.keystore.jks
spring.kafka.consumer.ssl.keystore-password=1234

将spring.kafka.ssl. ...用于生产者和消费者共有的属性。如果您没有消费者，请使用spring.kafka.producer.ssl. ...。
