spring.cloud.stream.kafka.binder.brokers=SASL_SSL://kafka-ons-internet.aliyun.com:8080
spring.cloud.stream.kafka.binder.configuration.security.protocol=SASL_SSL
spring.cloud.stream.kafka.binder.configuration.sasl.mechanism=ONS
spring.cloud.stream.kafka.binder.configuration.ssl.truststore.location=${kafka.ssl.truststore.location}
spring.cloud.stream.kafka.binder.configuration.ssl.truststore.password=KafkaOnsClient

spring.cloud.stream.kafka.binder.configuration.sasl.mechanism 和 spring.cloud.stream.kafka.binder.configuration.ssl.truststore.password 就用给出来的吗？还是要自己配置，如果要配置，请问怎么配置？
