Class SpringBeanParameterResolverFactory

java.lang.Object

org.axonframework.spring.config.annotation.SpringBeanParameterResolverFactory

All Implemented Interfaces:

org.axonframework.messaging.annotation.ParameterResolverFactory, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class SpringBeanParameterResolverFactory
extends Object
implements org.axonframework.messaging.annotation.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 the desired one can be designated with a Qualifier annotation on the parameter. By absence of a Qualifier annotation the bean marked as primary will be chosen. Note that when multiple beans are marked as primary, either one can be selected as parameter value.
