在 OpenJFX 中使用 SwingNode 时出现不满意的链接错误

Question

SwingNode 在使用 Spring Boot、OpenJFX 和 Maven 的应用程序中导致 Unsatisfied Link Error

我通读了有关此的帖子，尝试按照他们的建议进行操作（请参阅下面的代码），但无法解决我的问题。

有人可以帮忙吗？我哪里错了？

我正在使用我找到的 Maven 示例在 IntelliJ 中运行它。

DemoApplication

package com.javafxswingexplore.demo;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;

@SpringBootApplication
public class DemoApplication extends Application {

    private ConfigurableApplicationContext springContext;
    private FXMLLoader fxmlLoader;

    @Override
    public void init() throws Exception {

        System.setProperty("java.awt.headless", "false");

        springContext = SpringApplication.run(DemoApplication.class);
        fxmlLoader = new FXMLLoader();
        fxmlLoader.setControllerFactory(springContext::getBean);
    }

    @Override
    public void start(Stage stage) throws Exception {
        fxmlLoader.setLocation(getClass().getResource("/primary.fxml"));

        Parent root = fxmlLoader.load();
        Scene scene = new Scene(root);

        stage.setTitle("JavaFX and Maven");
        stage.setScene(scene);
        stage.show();
    }

    @Override
    public void stop() {
        springContext.stop();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

FXMLController

package com.javafxswingexplore.demo;

import javafx.embed.swing.SwingNode;
import javafx.fxml.FXML;
import org.springframework.stereotype.Controller;

import javax.swing.*;

@Controller
public class FXMLController {

    @FXML
    SwingNode swingNode;

    public void initialize() {

        createAndSetSwingContent(swingNode);
    }

    private void createAndSetSwingContent(final SwingNode swingNode1) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                swingNode1.setContent(new JButton("Click me!"));
            }
        });
    }
}

模块信息

module com.javafxswingexplore.demo {
    requires javafx.controls;
    requires javafx.fxml;
    requires javafx.swing;

    requires spring.boot;
    requires spring.boot.autoconfigure;
    requires spring.context;

    opens com.javafxswingexplore.demo to javafx.fxml, spring.core;
    exports com.javafxswingexplore.demo;
}

Answer 1

即使您有一个 Maven 项目，您也是从 IntelliJ 运行的（使用 Spring Boot 插件）。可以看到命令行：

"C:\Program Files\Java\jdk-12.0.1\bin\java.exe" \
--add-modules javafx.base,javafx.graphics \
--add-reads javafx.base=ALL-UNNAMED  --add-reads javafx.graphics=ALL-UNNAMED\

-Dspring.jmx.enabled=true -Dspring.liveBeansView.mbeanDomain \
-Dspring.application.admin.enabled=true \
"-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.1\lib\idea_rt.jar=58874:C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.1\bin" \

-m com.javafxswingexplore.demo/com.javafxswingexplore.demo.DemoApplication

所有的模块都是从你的 pom 的依赖中解析出来的。并且 JavaFX 依赖项是从 Maven Central 下载的。

但是，运行项目会抛出：

线程“JavaFX 应用程序线程”中的异常 java.lang.UnsatisfiedLinkError: com.sun.javafx.embed.swing.newimpl.SwingNodeInteropN.overrideNativeWindowHandle(Ljava/lang/Class;Ljdk/swing/interop/LightweightFrameWrapper;JLjava/lang /Runnable;)V

这意味着在本机库中找不到本机方法overrideNativeWindowHandle，在本例中为prism_common.dll，它与javafx-graphics-12.0.2-win.jar 捆绑在一起。

正如 cmets 中所讨论的，为了找出失败的原因，我们首先检查了默认存储本机库的本地缓存：但是 C:\Users\xxx\.openjfx\cache\12.0.2 不存在。

尝试添加不同的缓存文件夹（使用javafx.cachedir）也无效。

但添加 -Djavafx.verbose=true 有助于在控制台日志中找出原生库的来源：

从 java.library.path 加载 C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.1\jbr\bin\prism_common.dll

IntelliJ 正在从 java.library.path 加载 prism_common.dll，在本例中设置为路径为 C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.1\jbr\lib 的 JetBrains Runtime JBR。

可能这个JBR（无论是 8 还是 11）与 OpenJFX 源不匹配，这就是我们收到上面列出的错误的原因。

解决方案

在这种情况下，解决方案非常简单：不要依赖 JBR 库，而是直接依赖 OpenJFX 依赖项提供的库，方法是设置不同的路径。为此，只需转到 Run->Edit 配置，然后 Spring Boot -> Application，然后将此 VM 选项添加到 Environment：

-Djava.library.path=C:\temp

保存，然后再次运行。现在它应该可以按预期工作了。
