java - 在 JPA 实体内实例化 JavaFX 属性会导致 "Unable to load class"错误

Question

我在 war 中有以下类(class)。它也是唯一具有任何 JPA 注释的类:

@MappedSuperclass
public abstract class BaseEntity {
    protected ObjectProperty<Object> loc3 = new SimpleObjectProperty<>();
}

当我部署 war 时，出现以下错误:

但是如果我删除实例化

@MappedSuperclass
public abstract class BaseEntity {
    protected ObjectProperty<Object> loc3;
}

它有效。这也适用于 IntegerProperty。

没有 javafx beans 的比较:

@MappedSuperclass
public abstract class BaseEntity {
    Object loc3 = new Object();
}

无论有没有初始化都可以工作。这是为什么？

根据我读到的评论 Class Loading in WildFly根据访问JDK类下的内容，我将此jboss-deployment-struction.xml添加到我的src\main\webapp\WEB-INF 文件夹:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
    <deployment>
        <dependencies>
            <system export="true">
                <paths>
                    <path name="javafx/beans/property"/>
                    <path name="javafx/beans/binding"/>
                </paths>
            </system>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

即使属性位于 javafx.beans.property 下，这两个属性也是必需的，可能是因为它们的父类(super class)位于 .binding 中。
