问答 关于view的service注入问题

我的POJO

@View("Cai_sample_view")
@Data
public class Cai_sample_view implements Serializable{
    private static final long serialVersionUID = 1L;


    @Column
    @Comment("样品记录Id")
    @ColDefine(type= ColType.VARCHAR, width = 32)
    private String id;
}

我的service和impl

public interface CaiSampleViewService extends BaseService<Cai_sample_view> {

}


@IocBean(args = {"refer:dao"})
@Service(interfaceClass=CaiSampleViewService.class)
public class CaiSampleViewServiceImpl extends BaseServiceImpl<Cai_sample_view> implements CaiSampleViewService {
    public CaiSampleViewServiceImpl(Dao dao) {
        super(dao);
    }
}

当我尝试注入

    @Inject
    @Reference
    private CaiSampleViewService caiSampleViewService;

出现异常

CaiSampleViewServiceImpl在同一个maven 模块里面？

没有,我之前用插件生成的service和impl也出现这个问题,不在同一模板

我刚刚查看,CaiSampleViewServiceImpl确实是创建成功的,
在我尝试,出现异常

CaiSampleService caiSampleService = ioc.get(CaiSampleService.class);

如果不在同一个模块，那么所在模块启动后，才能启动当前模块，不然拿不到实例的

我启动过这个模板了,但是在web模板中还是取不到值

ioc.get是肯定拿不到的

那我怎么做才能在web注入进去呢
这是Controller的注入,但是,注入时就会出现错误

    @Inject
    @Reference
    private CaiSampleViewService caiSampleViewService;

先确定CaiSampleViewServiceImpl被扫描到, 被创建, 而且dubbo日志里面有出现他

日志里面只有两行说明

[INFO ] 17:25:34.853 org.nutz.ioc.loader.annotation.AnnotationIocLoader.addClass(AnnotationIocLoader.java:99) -    > add 'caiSampleServiceImpl                    ' - cn.wizzer.app.cai.modules.services.impl.CaiSampleServiceImpl

[DEBUG] 17:25:36.900 org.nutz.ioc.loader.combo.ComboIocLoader.printFoundIocBean(ComboIocLoader.java:226) - Found IocObject(caiSampleServiceImpl) in AnnotationIocLoader(packages=[cn.wizzer])

跟其他@Service类对比一下,看看差了些什么吧

dubbo日志里面有出现,但是,web里面没有办法注入

[INFO ] 17:25:38.759 com.alibaba.dubbo.config.ServiceConfig.exportLocal(ServiceConfig.java:539) -  [DUBBO] Export dubbo service cn.wizzer.app.cai.modules.services.CaiSampleViewService to local registry, dubbo version: 2.6.5, current host: 192.168.10.34

我看了一下dubbo日志,在服务端,确实已经注入了的,但是在消费端,我就没有看见

可需要远程服务?

@qq_32b899df 万分感谢

导入包错了

... 类重名了呀?

哇塞，蛋蛋还提供远程服务！！！
