I am attempting to use CDI over the deprecated ManagedBean/ManagedProperty annotations and run into this exception in a very simple web app:
Error creating bean with name 'navigationController': Unsatisfied dependency expressed through field 'message'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'java.lang.String' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@javax.inject.Inject(), @org.omnifaces.cdi.Param(validatorAttributes=[], validatorMessage=, validators=[], converter=, pathIndex=-1, converterAttributes=[], converterClass=interface javax.faces.convert.Converter, label=, overrideGlobalBeanValidationDisabled=false, required=false, disableBeanValidation=false, name=, validatorClasses=[], converterMessage=, requiredMessage=)}
I am attempting to follow the example of @Param in the OmniFaces showcase at http://showcase.omnifaces.org/cdi/Param.
I PUT to a page with http://localhost:8080/jsfSpringBootApp/nav.xhtml?message=My+message+from+MessageSource. It is my understanding that the NavigationController bean should be created on navigation to nav.xhtml and that the message field will be populated with the value taken from the request parameter.
IntellliJ also complains about the @Param annotation:
Cannot find bean qualified with @Param
Thank you for any help. I am stuck at what to try next.
The entire project is at https://[email protected]/david_maffitt/jsfspringbootapp.git.

I found that I had to add the dependency for cdi-api because I am deploying to tomcat 9.0.13 which doesn't have cdi baked in. The pom is derived from the joinfaces project.
You should do change in bean.xml set
