我正在尝试在 Spring Boot 应用程序中使用这种方法注册hibernate-types库提供的列表数组类型。不幸的是，当我从控制台启动应用程序时，它会抛出以下异常：

假设我有以下界面

public interface Handler {
    void handle(Object o);
}

和实现

public class PrintHandler implements Handler {
    void handle(Object o) {
        System.out.println(o);
    }
}
public class YetAnotherHandler implements Handler {
    void handle(Object o) {
        // do some stuff
    }
}

我想将所有Handler子类注入某个类

public class Foo {
    private List<Handler> handlers;
}

如何使用 Quarkus 实现这一目标？
