问答 dubbo annotation 无法发布

 <!--   <bean id="uploadService" class="com.supermap.file.UploadService"/>

    
    <dubbo:service interface="com.supermap.file.IUploadService" ref="uploadService"/> -->
    <dubbo:annotation package="com.supermap.file" />

service指定的可以发布，annotation无法发布这是为什么呢 @Service 注解都有

17 回复

基于注解的扫描

与官方写法一样, 声明一下需要扫描的package, 即可使用@Reference和@Service注解

<dubbo:annotation package="com.foo.bar.service" />

文档中这个怎么理解呢

换最新快照版试试

最新快照在哪儿呢？

nutz是什么版本的?

报告兽总 1.r.63

maven?? 普通javaee项目?? 怎么加的jar包??

整个项目是maven 单独引用的nutz-integration-dubbo-1.r.65-20171116.025018-1.jar

那可不行

下载了nutz-integration-dubbo 工程，做工程间的引用也不行

http://nutzam.com/core/basic/maven.html 你得配置快照库了

那怎么做呢

看文档,配repositories就好啦
