我的目标是使用不同的引导服务器在2个不同的通道中生成事件，使用jaas配置和SASL_SSL，但我无法设置通道以在引导服务器上正确进行身份验证。
我尝试了以下设置

mp.messaging.outgoing.channel1.bootstrap.servers=${KAFKA1}
mp.messaging.outgoing.channel1.ssl.endpoint-identification-algorithm=https
mp.messaging.outgoing.channel1.security.protocol=SASL_SSL
mp.messaging.outgoing.channel1.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="${KEY1}" password="${PWD1}";
mp.messaging.outgoing.channel1.sasl.mechanism=PLAIN

mp.messaging.outgoing.channel2.bootstrap.servers=${KAFKA2}
mp.messaging.outgoing.channel2.ssl.endpoint-identification-algorithm=https
mp.messaging.outgoing.channel2.security.protocol=SASL_SSL
mp.messaging.outgoing.channel2.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="${KEY2}" password="${PWD2}";
mp.messaging.outgoing.channel2.sasl.mechanism=PLAIN

使用此设置时，我收到通道初始化错误。

初始设置使用默认的bootstrap设置，它工作得很好，直到Kafka被带到方程中。

kafka.bootstrap.servers='${KAFKA1}'
kafka.ssl.endpoint-identification-algorithm=https
kafka.security.protocol=SASL_SSL
kafka.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="${Key1}" password="${PWD1}";
kafka.sasl.mechanism=PLAIN

我已经尝试了描述的问题，我不能弄清楚如何配置通道，以验证2个不同的引导服务器。
