We have spring-boot 1.5 & spring-boot-starter-amqp:1.5.22 application in aws cloud and working fine with rabbitmq ssl enabled. After spring-boot 2.0.9 migration, rabbitmq ssl failed with following error.
ERROR o.s.a.r.l.SimpleMessageListenerContainer - Failed to check/redeclare auto-delete queue(s).
org.springframework.amqp.AmqpIOException: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

Migration from Springboot 1.5 with rabbitmq to 2.0.9 Expected to connect rabbitmq with ssl enabled property.
Springboot2 we can skip the ssl certificate validation using setSkipServerCertificateValidation flag to true in rabbitmqconnectionfactory.
