nutzwk5.x，注入接口类报错，ProjectInfoService、ProjectInfoServiceImpl、ProjectController等等都是存在的，其中ProjectInfoServiceImpl有@IocBean、@Service和@CacheDefaults注解：

应该是重名了

感觉是改了package,但没install

@Wizzercn @wendal 没有重名，所有模块都重新mvn clean install了。可能原因：1，我把wk-models和wk-common两个模块合并了，但是包名依然还是cn.wizzer.app，是这个影响的吗？,，sys、cms、wx等模块注入都正常，只有我写的dubbo服务端工程注入错误。2，昨天把nutz版本升级到了1.r.68.v20201011，nutzboot升级到了2.4.1.v20201014。

重新看了看, 是没找到呢

@wendal 服务端工程启动日志里面显示ioc中已经有这个对象了

[DEBUG] 14:59:19.686 [main] org.nutz.ioc.loader.combo.ComboIocLoader - Found IocObject(projectInfoServiceImpl) in AnnotationIocLoader(packages=[cn.wizzer])

会不会是忘记实现接口了?

@wendal 应该不是，ProjectInfoService里面没有自定义方法

@IocBean(args = {"refer:dao"})
@Service(interfaceClass = ProjectInfoService.class)
@CacheDefaults(cacheName = "project_info")
public class ProjectInfoServiceImpl extends BaseServiceImpl<project_info> implements ProjectInfoService {
    public ProjectInfoServiceImpl(Dao dao) {
        super(dao);
    }

}

@Wizzercn @wendal 那个找到问题了，注入的时候必须加入@Reference注解，4.x的版本是不需要加这个注解的，首次使用nb，忽视了！
