Description

To be more flexible, the idea is to create some exchange properties

Put circuit state in an exchange property (2 status : Open / closed, as halfOpen do the same as closed in term of business)
use a Content Based Router to perform something like

from("direct:a")
.loadBalance()//
.circuitBreaker(3, 3000L, MyCustomException.class)
.choice()
.when(property(Exchange.CircuitBreaker_state).isEqualTo("closed"))
.to("direct:normalMode")
.when(property(Exchange.CircuitBreaker_state).isEqualTo("opened"))
.to("direct:degradedMode")
.end()
