使用javaFX 11自定义jre
作者:互联网
我正在使用JDK11和JavaFX11.
我使用Jlink为示例FX模块程序创建了一个自定义JRE,但是当我尝试使用该自定义JRE运行时,它将呈现以下错误:
这就是我创建自定义JRE的方式(无错误)
jlink --module-path ..\jmods;%PATH_TO_FX% --add-modules java.base,java.desktop,jdk.unsupported,javafx.graphics --output FXJRE
这就是我尝试运行的方式(有错误)
FXJRE\bin\java --module-path %PATH_TO_FX%;mods -m com.javafxdemo/com.javafxdemo.JavaFXDemo
错误消息:

这是我的编译方式:
源JavaFXDemo.java
package com.javafxdemo;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;
public class JavaFXDemo extends Application {
@Override
public void start(Stage stage) {
stage.setTitle("Hello World");
Group root = new Group();
Scene scene = new Scene(root, 300, 250);
Button btn = new Button();
btn.setLayoutX(100);
btn.setLayoutY(80);
btn.setText("Hello World");
btn.setOnAction(actionEvent -> System.out.println("Hello World"));
root.getChildren().add(btn);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
module-info.java
module com.javafxdemo {
requires javafx.base;
requires javafx.graphics;
requires javafx.controls;
exports com.javafxdemo;
}
这就是我的编译方式.
javac -d mods\com.javafxdemo --module-path %PATH_TO_FX% src\com.javafxdemo\module-info.java src\com.javafxdemo\com\javafxdemo\JavaFXDemo.java
编译后,我有如下模块类文件:
├───mods
│ └───com.javafxdemo
│ │ module-info.class
│ │
│ └───com
│ └───javafxdemo
│ JavaFXDemo.class
│
└───src
└───com.javafxdemo
│ module-info.java
│
└───com
└───javafxdemo
JavaFXDemo.java
我可以成功运行如下:
java --module-path %PATH_TO_FX%;mods -m com.javafxdemo/com.javafxdemo.JavaFXDemo
我可以使用默认的JDK11运行.
如何成功创建自定义JRE并运行示例FX模块程序?
解决方法:
如果转到此link,您将注意到每种平台的JavaFX发行版有两种:
JavaFX SDK是您使用的一种:
export PATH_TO_FX=/path/to/javafx-sdk-11/lib
如果检查lib下的文件,则这些文件为jar.
另一侧的JavaFX jmods包含jmod格式.
如果您读到有关jmod格式here的信息:
For most development tasks, including deploying modules on the module path or publishing them to a Maven repository, continue to package modules in modular JAR files. The jmod tool is intended for modules that have native libraries or other configuration files or for modules that you intend to link, with the jlink tool, to a runtime image.
换句话说,如果使用javac或java运行jar或模块,则可以使用SDK,但是如果使用jlink创建自定义JRE,则需要jmod版本.
下载jmods之后,解压缩它们并创建以下变量:
export PATH_TO_FX_JMOD=/path/to/javafx-jmods-11/
现在,您可以创建JRE:
jlink --module-path %PATH_TO_FX_JMOD%;mods --add-modules=com.javafxdemo --output FXJRE
并运行:
FXJRE/bin/java -m com.javafxdemo/com.javafxdemo.JavaFXDemo
