  org.axonframework.common.annotation.SpringBeanParameterResolverFactory

All Implemented Interfaces:

ParameterResolverFactory, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class SpringBeanParameterResolverFactory
extends Object
implements ParameterResolverFactory, org.springframework.context.ApplicationContextAware

ParameterResolverFactory implementation that resolves parameters in the Spring Application Context. A parameter can be resolved as a Spring bean if there is exactly one bean assignable to the parameter type. If multiple beans are available and one is marked as primary, that bean is chosen. Note that when multiple beans are marked as primary, either one can be selected as parameter value.
