Hello Guozhang,
For authentication I'm using the following configuration:
spring.kafka.properties.sasl.jaas.config =
org.apache.kafka.common.security.plain.PlainLoginModule required
username="<username>" password="<password> ";
spring.kafka.properties.ssl.truststore.location=/path/to/truststore.jks
spring.kafka.properties.ssl.truststore.password=trustore-secret
spring.kafka.properties.ssl.truststore.type=JKS
spring.kafka.properties.security.protocol=SASL_SSL
spring.kafka.properties.sasl.mechanism=PLAIN
defined in a .properties file. With 'acocunt' I mean the pair username/password
and the read/write rights the username has.
If a simplified code snippet may be useful, the stream is created as:
@Bean public KStream<String,Message> plain(StreamsBuilder builder) {
KStream<String,Message> stream = builder.stream( "A" );
stream.map( ... ).to( "B" );
return stream;
}
Thanks
Alessandro

Hello Alessandro,
Could you elaborate a bit more on what authN methanisms you are using, and by
`account` what do you mean explicitly?
