Question

我正在使用Jhipster生成器主版本。我添加了一个yo jhipster:entity collaborateur的实体一切顺利。
我已将项目导入Eclipse。

当我运行我的应用程序时，我收到此错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'collaborateurResource': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.myapp.rhapp.web.rest.mapper.CollaborateurMapper com.myapp.rhapp.web.rest.CollaborateurResource.collaborateurMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.myapp.rhapp.web.rest.mapper.CollaborateurMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

这是一个已知问题吗？我的项目配置有什么问题？
谢谢

我用yo jhipster创建了一个项目我跑了mvn compile
然后我跑了mvn来启动项目（还没有使用eclipse）
我收到了这个错误：

DTO Mappers由MapStruct注释处理器生成，您可以先运行mvn compile生成它们，并确保target/generated-sources链接为Eclipse中的源文件夹。

http://jhipster.github.io/configuring-ide-eclipse/

http://jhipster.github.io/using-dtos/

或许有一种方法可以将Eclipse配置为自动运行MapStruct注释处理器。

<强>更新

您可以看到错误消息“Adressedéjàutilisée”，因此请查看您是否有另一个进程正在侦听端口8080（可能是Tomcat）并停止它并重新启动您的应用程序或编辑您的application-*.yml，设置server.port属性为8080以外的其他内容并重新启动您的应用。
