Component Scan for custom annotation on Interface

Question

I have a component scan configuration as this:

   @Configuration
   @ComponentScan(basePackageClasses = {ITest.class},
                  includeFilters = {@C         


        

Answer 1

Creating a Dummy implementation seems quite hacky to me and all the steps Cemo mentioned require a lot of effort. But extending ClassPathScanningCandidateComponentProvider is the fastest way:

ClassPathScanningCandidateComponentProvider scanningProvider = new ClassPathScanningCandidateComponentProvider(false) {
    @Override
    protected boolean isCandidateComponent(AnnotatedBeanDefinition beanDefinition) {
        return true;
    }
};

Now you´re also able to scan for Interfaces with (custom) Annotations with Spring - which also works in Spring Boot fat jar environments, where the fast-classpath-scanner (which is mentioned in this so q&a) could have some limitations.
