jakarta-ee - IDEA错误 "Managed bean must be a concrete class, or is annotated with @Decorator"

Question

在我的 Java EE 项目中，我有一些抽象类。 IntelliJ IDEA 用红色下划线并告诉我:

Managed bean must be a concrete class, or is annotated with @Decorator

A top-level Java class is a managed bean if it is defined to be a managed bean by any other Java EE specification, or if it meets all of the following conditions:

• It is not a non-static inner class.
• It is a concrete class, or is annotated @Decorator.
• It is not annotated with an EJB component-defining annotation or declared as an EJB bean class in ejb-jar.xml.
• It has an appropriate constructor—either:
  • the class has a constructor with no parameters, or
  • the class declares a constructor annotated @Inject.

我只想使用抽象类，没有任何注释。尽管 IntelliJ 告诉我这是一个错误，但我的 JBoss 服务器并没有提示它。

有什么解释吗？

Answer 1

我的猜测是，这是设置 > 编辑器 > 检查 > CDI(上下文和依赖注入(inject))中的托管 Bean 不一致错误检查。其严重性为错误，因此将用红色波浪线下划线。

看来您并不真正关心此检查，因此只需取消选择它并保存您的更改。
