Dubbo - 當當網?

public interface DependencyService {public String dependency() throws Exception; } import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;import bhz.dubbo.dependency.provider.DependencyService; import bhz.dubbo.sample.provider.SampleService; @Service("dependencyServiceImpl") @com.alibaba.dubbo.config.annotation.Service(interfaceClass=com.dubbo.dependency.provider.DependencyService.class, protocol={"dubbo"}, retries=0) public class DependencyServiceImpl implements DependencyService {//注入SampleService@Autowiredprivate SampleService sampleService;public String dependency() throws Exception {//這里 我們可能需要調用SampleService，也可能不需要...System.out.println(sampleService.sayHello("jack"));return "dependency exec";}}

啟動時檢查?
