实例化JPA实体内的JavaFX属性导致“无法加载类”错误

我在战争中拥有以下类。这也是任何具有JPA批注的唯一一类：实例化JPA实体内的JavaFX属性导致“无法加载类”错误

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

当我部署战争，我得到了以下错误：

，但如果我删除实例

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

它作品。这也适用于IntegerProperty。

为了对比不JavaFX的豆类：

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

作品有或没有初始化。这是为什么？

检查您的版本运行的Java版本和运行服务器的版本。 – Thihara

@Thihara尽我所见，他们都使用'JVM版本：1.8.0_112' – Mark

一旦你确定该类实际上在CLASSPATH /可访问。你的JPA提供者知道如何坚持ObjectProperty吗？不在JPA规范中的ObjectProperty类型。你面前有答案。你有@AttributeConverter，如果你想定义如何保持这种类型... –

走向所作的评论我读Class Loading in WildFly并根据什么下写访问的JDK类我加这jboss-deployment-structure.xml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>

两者都需要，即使性能javafx.beans.property可能在定位，因为其超类是.binding。
