Java Quarkus中的JAX-RS子资源问题,java,quarkus,Java,Quarkus,我试着亲自品尝夸克并将一个工作样本从my迁移到Quarkus，但它没有按预期工作我遇到了一个异常，比如当保存帖子的评论时 curl-X POSThttp://localhost:8080/posts/ffba7fa8-d804-403c-8812-9ab2a0d3c16b/comments-d“{”content\：\“test comments\”}”-H“内容类型：application/json” CommentResource在PostResource中注册 @Path（“post

我试着亲自品尝夸克

并将一个工作样本从my迁移到Quarkus，但它没有按预期工作

我遇到了一个异常，比如当保存帖子的评论时

curl-X POSThttp://localhost:8080/posts/ffba7fa8-d804-403c-8812-9ab2a0d3c16b/comments-d“{”content\：\“test comments\”}”-H“内容类型：application/json”

CommentResource
在
PostResource
中注册

@Path（“posts”） @请求范围公共类邮政资源{ //省略了其他方法 @路径（“{id}/注释”）公共评论资源评论资源（）{ 返回resourceContext.getResource（CommentResource.class）； } }
注释资源代码如下所示

@RequestScoped 公共类评论资源{ 私有最终静态记录器Logger=Logger.getLogger（CommentResource.class.getName（））；私人最终评论； @上下文 UriInfo-UriInfo； @上下文资源语境资源语境； @路径参数（“id”）字符串posted； @注入公共CommentResource（CommentRepository CommentRepository）{ this.comments=commentRepository； } @得到公众响应getAllComments（）{ 返回ok（this.comments.allByPostId（this.postId））.build（）； } @职位公共响应保存注释（注释注释表单）{ Comment saved=this.comments.save（Comment.of（this.postId，commentForm.getContent（））；创建的返回( uriInfo.getBaseUriBuilder（） .path（“/posts/{id}/comments/{commentId}”） .build（this.postId，saved.getId（）） ).build（）； } }

CDI和RestEasy Inject提供程序似乎无法识别
CommentResource
中的
CommentRepository
现在，我认为您可以通过将
@Unremovable
注释添加到
CommentResource
类来解决这个问题
您可能还必须添加
@RegisterForReflection
注释

我们将看看是否能找到更好的方法来自动检测子资源，并为您这样做。
有没有理由像这样使用
PostResource
？@LutzHorn没有理由，它应该得到Jaxrs的支持。我在标准JavaEE应用程序（部署在Wildlfy等应用程序中）和最新的Helidon框架中使用过这种风格，它们都工作得很好。
