JavaFX apllication不与Selenium WebDriver一起运行

本文介绍了JavaFX apllication不与Selenium WebDriver一起运行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想在JavaFX应用程序中使用Selenium WebDriver，我想获取网页的屏幕截图并在JavaFX应用程序的ImageView中显示它。

I want to use Selenium WebDriver in JavaFX application that I want to get a screenshot of a webpage and show it in ImageView in JavaFX app.

此代码完全有效罚款截取网页并保存：

This code works completely fine to take screenshot of webpage and save it:

package application; import java.io.File; import org.apachemons.io.FileUtils; import org.openqa.selenium.OutputType; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.phantomjs.PhantomJSDriver; public class Main{ public static void main(String[] args) throws Exception { File file = new File("E:\\Eclipse_Projects\\phantomjs-2.1.1-windows\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe"); System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.14.0-win64\\geckodriver.exe"); System.setProperty("phantomjs.binary.path", file.getAbsolutePath()); WebDriver driver = new PhantomJSDriver(); driver.get("google"); // taking screenshot File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(screenshot, new File("screenshot.png")); driver.close(); System.out.println("Done!"); } }

为了在JavaFX app中使用保存的屏幕截图我试图对这个类做一些简单的修改，使它成为一个JavaFX应用程序。

In order to use the saved screenshot in JavaFX app I tried to make some simple modifications to this class to make it a JavaFX app.

这是修改后的代码：

import org.apachemons.io.FileUtils; import org.openqa.selenium.OutputType; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.phantomjs.PhantomJSDriver; import javafx.application.Application; import javafx.stage.Stage; public class Main extends Application{ public static void main(String[] args) throws Exception { File file = new File("E:\\Eclipse_Projects\\phantomjs-2.1.1-windows\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe"); System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.14.0-win64\\geckodriver.exe"); System.setProperty("phantomjs.binary.path", file.getAbsolutePath()); WebDriver driver = new PhantomJSDriver(); driver.get("google"); // taking screenshot File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(screenshot, new File("screenshot.png")); driver.close(); System.out.println("Done!"); launch(args); } @Override public void start(Stage primaryStage) throws Exception { primaryStage.show(); } }

这是带有一些代码的最简单的JavaFX应用程序之一在main方法中，当我运行它时，它应该保存屏幕截图并打开一个空白的JavaFX应用程序。但是当我运行它时，它什么也没做，它甚至都没有执行main方法。它在1-2秒后终止而没有做任何事情。

This is one of the simplest JavaFX applications with some code in main method and when I run it, it should save the screenshot and open a blank JavaFX app. But when I run it, it does not do anything, it does not even execute the main method. It gets terminated after 1-2 seconds without doing anything.

然后我意识到当Selenium Webdriver库在构建路径中时，JavaFX应用程序不会运行。即使我从类中删除了所有Selenium的东西，它也会遇到同样的问题。

Then I realized that JavaFX application does not run when Selenium Webdriver library is in the build path. That even if I delete all Selenium stuff from the class, it ends up with the same problem.

package application; import javafx.application.Application; import javafx.stage.Stage; public class Main extends Application{ public static void main(String[] args) throws Exception { launch(args); } @Override public void start(Stage primaryStage) throws Exception { primaryStage.show(); } }

上述代码仅在我删除Selenium WebDriver库时运行来自项目的构建路径。

The code above runs only when I delete Selenium WebDriver library from the project's build path.

我在两个IDE中尝试了这些：在Eclipse中，程序在1-2秒后终止，没有做任何事情，没有任何错误。 在NetBeans中，程序在1-2秒后终止而没有做任何事情，但它给了我一个错误：

I have tried these in two IDEs: In Eclipse, the program gets terminated after 1-2 seconds without doing anything and without any error. In NetBeans, the program gets terminated after 1-2 seconds without doing anything but it gives me an error:

C:\Users\User\AppData\Local\NetBeans\Cache\8.2\executor-snippets\run.xml:53: Java returned: -1073740791 BUILD FAILED (total time: 2 seconds)

我用Java编写代码差不多2年了，但它是我第一次遇到这样的问题。我google了很多，没有找到类似的东西。

It is almost 2 years that I am writing code in Java, but it is the first time that I come across such a problem. I googled a lot and didn't find anything similar to this.

有没有人知道这里发生了什么，问题是什么？任何想法都将不胜感激。

Does anyone have an idea what is going on here and what is the problem? Any idea would be appreciated.

编辑：当我在IDE之外运行生成的jar文件时，它正常工作。

it works normally when I run the generated jar-file outside of IDE.

感谢您的考虑。

推荐答案

我刚刚找到了这个问题的原因。问题与NVIDIA驱动程序有关。我使用的是版本378.49，我回滚到版本376.33。现在，问题解决了。您可以在 intellij-support.jetbrains/hc/en-us/community/posts/115000060510-Process-finished-with-exit-code-1073740791-0xC0000409-JavaFX-应用程序

I just found the reason of this issue. The problem is related to the NVIDIA Driver. I was using version 378.49 and I rolled back to version 376.33. Now, the problem is solved.

感谢@KrishnanMahadevan提醒我使用IntelliJ IDE。
