@IocBean
public class AliCdnService {
    private static final String cdn_server_address = "https://cdn.aliyuncs.com";
    @Inject
    private AliConfiguration aliConfiguration;//未注入

@IocBean
public class AliyunService{
    @Inject
    private AliConfiguration aliConfiguration;//成功注入

@IocBean
public class AliConfiguration {

    @Inject("java:$conf.get('ali.article.bucketName')")
    private String artBucketName;

统一包下的俩个服务，是什么原因造成的呢

日志里面有提示AliCdnService的ioc定义从哪里加载

成功注入的日志

是哪部分需要关注呢？我没看出来

启动日志贴一下


[DEBUG] 2017-11-28 11:09:25,118 org.nutz.ioc.loader.annotation.AnnotationIocLoader.addClass(AnnotationIocLoader.java:80) - Found @IocBean : class cn.wizzer.app.web.commons.config.AliConfiguration

启动日志中已经加载过啦

搜AliCdnService字样的日志,贴出来

贴全呗
看看AliCdnService有没有加载，它也要是被Ioc容器管理的才行
AliCdnService不会是你自己new的吧？

是通过
@IocBean注入的Service 不是自己new的

debug一下AliCdnService的构造方法,看看哪里调用过.

另外, 是不是没编译/install
