provider registration :It need attribute“scan: base-packages: ”label but do not need value.Because it always scan the package and its children-packages where start-up class in, no matter what value you attribute about dubbo

Whether the @DubboService annotation takes effect depends on whether the ServiceAnnotationPostProcessor exists

ServiceAnnotationPostProcessor has 2 functions

1. Scan all classes under the given path to find classes with DubboService related annotation types. Create BeanDefinition and register it in the spring container (ServiceBean instance)
2. Traverse all BeanDefinition objects in the container, process the DubboService related annotation on the @Bean method, create a BeanDefinition and register it in the spring container (ServiceBean instance)

In the springboot dubbo project, there are two conditions for whether ServiceAnnotationPostProcessor is created (either one can be met). If it exists at the same time, multiple ServiceAnnotationPostProcessor instances will be created.

1. Using the @EnableDubbo annotation will create a ServiceAnnotationPostProcessor instance. The corresponding scanpackage path is the scanBasePackages attribute. When the attribute scanBasePackages is not set, the package path of the startup class is used by default.
2. Configuring dubbo.scan.base-packages (regardless of whether it has a value) will create a ServiceAnnotationPostProcessor instance
