我无法通过NetBeans中的“dist文件夹”中的.jar运行javaFX应用程序。

但是如果我从netBeans运行项目，一切都很完美。如果我尝试（稍后在NetBeans中运行）从dist文件夹启动应用程序，一切都很完美。事实上

所以我认为这个问题是由Java.Lang.SecurityException引起的（是的，我知道log4j属性存在问题），也许这里https://github.com/marcojakob/javafx-ui-sandbox/issues/5有一个解决方案，但为什么??

1 个答案:

答案 0 :(得分：1)

问题是什么

在某些情况下，您链接到的javafx-ui-sandbox项目已过时且与以后的JavaFX版本不兼容。

如何解决

我建议使用ControlsFX代替。 ControlsFX具有javafx-ui-sandbox（以及更多）的所有功能，并且构建为不与JavaFX系统类冲突。它也是一个更积极维护和开发的项目。

如果您无法使用最新版本的ControlsFX所需的最低Java 8版本，则曾经有ControlsFX 2.x backport，但它不再具有任何相关内容。

在

之后进行了长时间的不必要的解释

javafx-ui-sandbox是一个原型系统，它包含与某些Java发行版中包含的类冲突的类 - 这就是你得到的原因：

Caused by: java.lang.SecurityException: class "javafx.scene.control.Dialogs"'s 
  signer information does not match signer information of other classes 
  in the same package.

这里发生的是你在一个jar中包含一个javafx-ui-sandbox类（javafx.scene.control.Dialogs）并对其进行签名（可能你使用的是NetBeans和have the checkbox to self-sign jars switched on，但还有其他你可以签署的方式）。因此，您使用与Oracle用于签署JavaFX jar的证书不同的证书来签署您的罐子。 JavaFX jar包含javafx.scene.control包中的大部分代码。作为Java的一些模糊规则的一部分，您不能使用两个不同的证书在同一个包中签名代码，否则它将生成安全性异常。

在NetBeans中执行时，您可能没有看到问题，因为您没有在开发环境中对应用程序进行签名以执行它，但是当您构建正在执行的jar文件时，您也在签署jar文件文件，此时罐子不起作用。

您可以轻松修复javafx-ui-sandbox源代码并将包名称从javafx.scene.control更改为其他内容（例如com.yourcompany.control）。这样，类包不会与为JavaFX系统提供的默认包冲突，您可以在不引起任何问题的情况下签署代码（包括com.yourcompany.control.Dialogs类）。但同样，您可能最好使用ControlsFX库。
