我正在尝试在 Quarkus 中迁移 Spring Boot 应用程序。 经过一番尝试后，我发现并非所有的 beans 都被发现，因此我尝试遵循本指南并创建一个 jandex 索引 https://quarkus.io/guides/cdi-reference 。 除了 spring-web Artifact 之外，所有其他依赖项都很容易发现，但是当到了 spring-web 的时候，它会显示:
无法解析 Artifact org.springframework:spring-web:null
存储库应该是 https://mvnrepository.com/artifact/org.springframework/spring-web/4.3.28.RELEASE
这是我的 application.yaml 文件。
quarkus:

log:

spring-hateoas:

artifact-id: spring-hateoas
spring-web:

artifact-id: spring-web
然后，当我尝试构建项目时，它会显示一条错误消息:

我尝试使用分类器，但这没有改变任何东西。
当我尝试删除 quarkus.index-dependency.spring-web 属性并尝试构建时，它显示:

感谢您的帮助!
最佳答案
我收到了 quarkus 支持人员的答复，你可以在那里找到它 https://quarkusio.zulipchat.com/#narrow/stream/187030-users/topic/Quarkus.20CDI.3A.20Spring-Web.20Artifact.20Could.20Not.20Be.20Resolved .
简而言之:
- 您必须使用 Quarkus 扩展来获取兼容依赖项列表，您可以在此处找到 https://quarkus.io/guides/#compatibility .
- 如果您已经有 springboot 应用程序，迁移到 Quarkus 的唯一方法是更改很少的代码以遵守 Quarkus 的限制
干杯
