将 sasl.jaas.config 添加到 payara 上的 Kafka MDB

Question

@MessageDriven(name = "KafkaMDB", activationConfig = { @ActivationConfigProperty(propertyName = "bootstrapServersConfig", propertyValue = "ab-cde-xyz-stage.crb.axxxxx.net:9093"), @ActivationConfigProperty(propertyName = "clientId", propertyValue = "sp-document-processor"), @ActivationConfigProperty(propertyName = "groupIdConfig", propertyValue = "AMPSEM.consumerGroup.v1"), @ActivationConfigProperty(propertyName = "topics", propertyValue = "teat.topic.any.v2"), @ActivationConfigProperty(propertyName = "autoOffsetReset", propertyValue = "earliest"),
@ActivationConfigProperty(propertyName = "autoCommitInterval", propertyValue = "100"),
@ActivationConfigProperty(propertyName = "retryBackoff", propertyValue = "1000"),
@ActivationConfigProperty(propertyName = "keyDeserializer", propertyValue = "org.apache.kafka.common.serialization.StringDeserializer"),
@ActivationConfigProperty(propertyName = "valueDeserializer", propertyValue = "org.apache.kafka.common.serialization.StringDeserializer"),
@ActivationConfigProperty(propertyName = "pollInterval", propertyValue = "30000"),
@ActivationConfigProperty(propertyName = "additionalProperties", propertyValue = "ssl.truststore.location=/u01/oracle/application/config/ext/pp.tenant.truststore.jks," + "ssl.truststore.password=12345,ssl.keystore.location= /u01/oracle/application/config/ext/pp.tenant.sr.keystore.jks,ssl.keystore.password=12345," + "sasl.mechanism=SCRAM-SHA-256,security.protocol=SASL_SSL,**sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username\="pp.ampsem.v1" password\="12345**"") })

Can Anyone help me in adding sasl.jass.config property to KafkaConsumer that I have created using Payara MDB. I am trying as above, but does not work.

Thanks

I was running into the same issue, it appears someone else was as well and created a contribution to the cloud connectors project, here is the pull request -> https://github.com/payara/Cloud-Connectors/pull/97

The issue arises because of the '=' sign in the sasl.jaas.config parameter, this is used for splitting properties from their value in the kafka connector.

By wrapping the variable value in single quotes, the entire string is taken and the sasl.jaas.config string can be loaded into the system.

@MessageDriven(name = "KafkaMDB", activationConfig = {
    @ActivationConfigProperty(propertyName = "additionalProperties", propertyValue = "sasl.jaas.config='org.apache.kafka.common.security.plain.PlainLoginModule required username=${sasl.jaas.connection.string} password=${sasl.jaas.connection.secret};'"))
