我正在尝试使用 DeltaSpike Data模块 Weld ，但每个类都用 @Repository 注释在我的 IDE 中显示警告，并在运行时显示异常。
我尝试遵循DeltaSpike documentation多次检查Baeldung ，以及各种文章/论坛，但尚未找到解决方案。
有谁知道我可能会缺少什么来允许正确注入(inject)存储库？
IDE 警告
Managed Bean must be a concrete class or @Decorator
运行时异常
org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type ExampleRepo with qualifiers @Default
at injection point [BackedAnnotatedParameter] Parameter 1 of [BackedAnnotatedConstructor] @Inject public com.example.myapp.services.ExampleService(ExampleRepo)
示例存储库
@Repository(forEntity = Data.class)
public interface ExampleRepo extends EntityRepository<Example, Long> {
Data findExampleById(long id);
@Modifying
@Query("UPDATE Data AS e SET e.locale = ?1 WHERE e.id = ?2")
int updateLocale(final Locale locale, final long id);
@Modifying
@Query("UPDATE Data AS g SET g.reactTranslation = ?1 WHERE g.id = ?2")
int updateReactTranslation(final boolean toggle, final long id);
}
Gradle
plugins {
id "io.spring.dependency-management" version "1.0.8.RELEASE"
}
ext {
deltaSpikeVersion = "1.9.2"
}
dependencies {
// DeltaSpike Extensions
implementation "org.apache.deltaspike.modules:deltaspike-data-module-api:${deltaSpikeVersion}"
runtimeOnly "org.apache.deltaspike.modules:deltaspike-data-module-impl:${deltaSpikeVersion}"

}
dependencyManagement {
imports {
mavenBom "org.apache.deltaspike.distribution:distributions-bom:${deltaSpikeVersion}"
}
}
为了澄清，以下也是项目的隐式依赖项。
最佳答案
我错过了 Java SE 特定指令: https://deltaspike.apache.org/documentation/cdiimp.html#javase6
我必须使用 DeltaSpike 的 CdiContainer 而不是 Weld 的 SeContainer。
dependencies {
implementation "org.apache.deltaspike.cdictrl:deltaspike-cdictrl-api:${deltaSpikeVersion}"
runtimeOnly "org.apache.deltaspike.cdictrl:deltaspike-cdictrl-weld:${deltaSpikeVersion}"
}
