CUBA如何新增ServiceBean

<entry key="cip_ProjectCoordsService"
       value="cn.com.dataocean.cip.service.ProjectCoordsService"/>

package cn.com.dataocean.cip.service;
import java.util.List;
public interface ProjectCoordsService {
    String NAME = "cip_ProjectCoordsService";
    List<String> getLookupFieldList(String flag);
}

@Service(ProjectCoordsService.NAME)
public class ProjectCoordsServiceBean implements ProjectCoordsService {
}

@Inject
protected ProjectCoordsService projectCoordsService;
