jpa - Quarkus 运行时不注入(inject) EntityManager

Question

我尝试了 @PersistenceContext、@PersistenceUnit 和 @Inject 组合，但没有任何效果。 @Inject 失败 maven-quarkus-plugin 构建:

[ERROR] Caused by: javax.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type javax.persistence.EntityManager and qualifiers [@Default]

我试过使用和不使用 persistence.xml。我的数据源和 application.properties 工作正常，因为我可以注入(inject) AgroalDataSource 并直接执行 JDBC，但我想移植我的 JPA 实体类并使用它们。

我的父模块pom

我想通了!不是真正的“直观”，但我还没有迁移到任何实体类。所要做的就是将一个类放在范围内，一切都开始工作了。简单的原型(prototype)制作到此为止。也许它应该警告“找不到实体类”。
