1. Use the following code to make a generalization call of the bean mode

2.   public interface DemoService {
       String sayHello(String name);
   }

3. ReferenceConfig<GenericService> referenceConfig = new ReferenceConfig<>();
       referenceConfig.setInterface(DemoService.class.getCanonicalName());
       applicationConfig.setRegistry(registryConfig);
       referenceConfig.setApplication(applicationConfig);
       referenceConfig.setGeneric(GENERIC_SERIALIZATION_BEAN);
       GenericService genericService = referenceConfig.get();
   JavaBeanDescriptor result = (JavaBeanDescriptor)genericService.$invoke("sayHello", new String[]{"java.lang.String"}, new Object[]{JavaBeanSerializeUtil.serialize(null)});

Expected Behavior
