从这个堆栈跟踪中，我认为FXML文件中可能存在一些问题，因为第二行尚未打印。但我的问题是为什么它没有显示任何错误消息？我正在使用SceneBuilder。我创建了一个空的FXML文件，它正在加载

我认为没有必要描述代码，因为它们是自解释的。我已经确定一些xml代码是xml映射文件中的问题。我想我终于找到了问题所在

如果我在xml映射文件的问题区域内保持代码活动，那么问题就发生了。但是如果我评论这些台词，那么这个节目开始得很好

另一个问题是，如果这些行处于活动状态，则在ApplicationContextSingleTon类中，“AC_行3”不会被打印。表示应用程序正在“AC_第2行”停止

我想我已经正确地映射了这些类。当我使用Netbeans时，如果我在问题区域中映射的类名上执行ctrl+clik，Netbeans将带我去类

现在我有两个问题：

为什么我没有得到完整的堆栈跟踪

这些线路有什么问题

我几乎没有遇到这个问题，也不明白为什么没有打印异常。和你一样，我也试着用try-catch来环绕我的整个启动方法。结果证明STDERR没有被发送到正确的位置。我发现这一点的方法是（再次）尝试捕获，并使用

System.out.println（ex）

而不是

ex.printStackTrace（）

。您还可以使用

ex.printStackTrace（System.out）

我想我参加聚会迟到了，但希望我能帮助任何可能遇到同样问题的人。

我最近遇到了打印“启动方法中的异常”，但没有打印堆栈跟踪的问题。捕获异常的解决方案（至少对我来说）是捕获可丢弃的

而不是异常
。例如：
@Override
public void start(Stage stage) throws Exception {
    try {
        //... start method code here
    } catch(Throwable t) {
        t.printStackTrace()
    }
}

如何初始化SpringDI？？将CDI挂接到FXMLLoader的位置？？？这可能不是解决方案，但最好将其排除在外。。。有可能满足JavaFXAPI版本警告中提到的条件吗？@Rafael Guillen，对不起，我不熟悉CDI。我在重写的“initialize”方法中使用bean by application context。当我说CDI时，我指的是Spring DI，您如何将Spring框架集成到JavaFx？出于某种原因，它可能是您所看到的全部，但它不是完整的堆栈跟踪。为了诊断问题，您需要弄清楚如何获取完整的堆栈跟踪。您是否真的到达了catch
块？如果是这样的话，您真的应该从代码中看到剩余的堆栈跟踪？？将CDI挂接到FXMLLoader的位置？？？这可能不是解决方案，但最好将其排除在外。。。有可能满足JavaFXAPI版本警告中提到的条件吗？@Rafael Guillen，对不起，我不熟悉CDI。我在重写的“initialize”方法中使用bean by application context。当我说CDI时，我指的是Spring DI，您如何将Spring框架集成到JavaFx？出于某种原因，它可能是您所看到的全部，但它不是完整的堆栈跟踪。为了诊断问题，您需要弄清楚如何获取完整的堆栈跟踪。您是否真的到达了catch
