Why i am getting this error here. I am using RabitMQ as a broker
Addition: I have seen that if I comment out the enableStompBrokerRelay in my WebSocketConfig and enable correspondignlly the simple broker i.e.
config.enableSimpleBroker("/topic/", "/queue/");
the app starts just fine.
So this is some configuration issue. netstat -apn shows that my rabbit is listenning on port 127.0.0.6 port 61613 as expected.
tcp 0 0 127.0.0.6:61613 0.0.0.0:* LISTEN 2318/beam.smp
credentials of guest guest are also good i.e. i connected to http://localhost:15672/ made sure that guest user exists and it has the admin rights.
the question is now what is this Reactor2StompCodec class supposed to do. I am not able to find sample working configuration on the github
ADDITION 18 June 2015: I was not able to understand the problem but i found a workaround i.e. spring-boot-starter-parent : 1.2.5.BUILD-SNAPSHOT and i forced the spring security version in my pom file trough an property i.e. spring-security.version : 4.0.2.CI-SNAPSHOT . With this constelation it does work. It is interesting that if i change the spring-boot-starter-parent to 1.3.0.BUILD-SNAPSHOT or 1.3.0.M1 it does not work. So maybe this has something to do with the spring boot project. At least i have a workaround now where i can use spring security 4.0
found the answer i.e. from the link below:
"The latest version of Spring needs reactor 2.0, "
https://github.com/spring-projects/spring-boot/issues/3459
Changed the reactor groupid to the one below and it all works now :
