Thanks for the quick reply Claus.
That did indeed help. It seems we must then change any existing routes declared
as 'from("servlet:http://0.0.0.0:9080/test/endpoint3";)' instead of
'from("undertow:http://0.0.0.0:9080/test/endpoint3";)'.
The camel-hystrix-starter does need to be removed now though. It results in the
following error:
BeanDefinitionOverrideException: Invalid bean definition with name
'servletRegistrationBean' defined in class path resource
[org/apache/camel/component/servlet/springboot/ServletMappingAutoConfiguration.class]:
Cannot register bean definition [Root bean: class [null]; scope=;
abstract=false; lazyInit=null; autowireMode=3; dependencyCheck=0;
autowireCandidate=true; primary=false;
factoryBeanName=org.apache.camel.component.servlet.springboot.ServletMappingAutoConfiguration;
factoryMethodName=servletRegistrationBean; initMethodName=null;
destroyMethodName=(inferred); defined in class path resource
[org/apache/camel/component/servlet/springboot/ServletMappingAutoConfiguration.class]]
for bean 'servletRegistrationBean': There is already [Root bean: class [null];
scope=; abstract=false; lazyInit=null; autowireMode=3; dependencyCheck=0;
autowireCandidate=true; primary=false;
factoryBeanName=org.apache.camel.component.hystrix.springboot.HystrixMappingAutoConfiguration;
factoryMethodName=servletRegistrationBean; initMethodName=null;
destroyMethodName=(inferred); defined in class path resource
[org/apache/camel/component/hystrix/springboot/HystrixMappingAutoConfiguration.class]]
bound.
It works if I change back to the "regular" camel-hystrix dependency. Would that
be correct?
Kind regards

Hi
You should use camel-servlet-starter to tie to the undertow from spring boot
itself.
