### Environment

* Dubbo version: 2.7.0
* Operating System version: mac
* Java version: 1.8

### Steps to reproduce this issue

1. Start dubbo provider in 2.7.0 SpringBoot Annotation mode
```
@SpringBootApplication
@DubboComponentScan
public class SpringBootProvider {
  public static void main(String[] args) {
    new EmbeddedZooKeeper(2181, false).start();
    SpringApplication.run(SpringBootProvider.class);
  }
}
```

2. set parameters as 2.5.10 for the ServiceBean.
```
@Service(parameters = {"key","value"})
public class DemoServiceImpl implements DemoService {

}
```
3. run SpringBootProvider to start the service

Pls. provide [GitHub address] to reproduce this issue.

### Expected Result

The service has been started and register to zookeeper.

### Actual Result

It throws exception as below, service cannot be started up.

With my investigation, ConstructorArgValue discard in ServiceAnnotationBeanPostProcessor, which caused the issue. 
```
private AbstractBeanDefinition buildServiceBeanDefinition(Service service, Class<?> interfaceClass,
                                                              String annotatedServiceBeanName) {

        BeanDefinitionBuilder builder = rootBeanDefinition(ServiceBean.class)
                .addConstructorArgValue(service)
                // References "ref" property to annotated-@Service Bean
                .addPropertyReference("ref", annotatedServiceBeanName)
                .addPropertyValue("interface", interfaceClass.getName());
}
