从JavaFX项目A运行JavaFX项目B
从JavaFX项目A运行JavaFX项目B
提问于 2022-08-23 08:40:21
01:目标
我想从一个JavaFX项目A运行一个JavaFX项目B
02: config
linux，eclipse，openJDK17
03:信息
当我运行Java (HelloWorld打印到控制台)时，项目A编译、运行和运行项目B，它可以工作
在此说明：
//
ProcessBuilder process01 = new ProcessBuilder("/usr/bin/java", "HelloWorld.java");
//
process01.directory(new File("../HelloWorld/src/org/example/"));
//
return process01
.inheritIO()
.start()
.waitFor();04:信息
JavaFX项目B只是一个带有按钮和TextField的阶段，单击Button，日期就会出现在TextField中。
05:信息
我尝试了Liberica完全JDK 18，Oracle JDK 18
06: information
我试图将JREs转换为eclipse。
07: information
我试图将项目B添加到ClassPath的项目A中
我试图将项目B添加到ModulePath的项目A中
08:从JavaFX项目A运行JavaFXproject B的代码(多次尝试，不起作用)

par le callback, service 01, etat, success很多评论给你看，我试过的说明。
如前所述，我已经尝试将JDK、JREs设置为JavaFX项目B为ClassPath和/或ModulePath的JavaFX项目A。
我也试过这个链接
https://openjfx.io/openjfx-docs/#install-javafx
尝试进入终端但不改变PATH_TO_FX
在这里，命令行：
java --module-path /media/sambano/home_HDD_EXTERNE/Documents/java/workspace_eclipse/JavaFX_Test29_Threads_Services_Processes/utilitaires/javafx-sdk-18.0.1/lib --add-modules javafx.controls,javafx.fxml,javafx.base,javafx.graphics /media/sambano/home_HDD_EXTERNE/Documents/java/workspace_eclipse/JavaFX_Test29_Threads_Services_Processes/src/application/Main.java我带着JRE回到了openJDK17，从ModulePath和ClassPath的项目A中删除了JavaFX项目B，只是为了获得一个干净的情况(以避免误解)。
我不想使用.jar
有什么方法可以告诉我一步一步地达到目标吗？有什么建议吗？或者想法？
谢谢。

它有JavaFX二进制文件
@FXML
private void executerFichierJava02() {
//
System.out.println("");
System.out.println("method: executerFichierJava02()");
System.out.println("create 1 Service and 1 Task");

System.out.println("execute 1 Java class (from project JavaFX_Test02_Desvstory)");
final Service<Integer> service01 = new Service<Integer>() {
// --- step 03, override createTask() method
@Override
protected Task<Integer> createTask() {
return new Task<Integer>() {
// --- step 04, override call() method

ProcessBuilder process01 = new ProcessBuilder("/usr/bin/java", "-p", "./out", "-m", "JavaFX_Test01_Hello_Devstory/application.Main");
//

}
};
}
};
// --------------------------------------------------------

// 2° possibilité, en utilisant des callbacks
service01.setOnReady(event -> {
System.out.println("par le callback, service 01 ready");
});
service01.setOnScheduled(event -> {
System.out.println("par le callback, service 01 scheduled");
});
service01.setOnRunning(event -> {
System.out.println("par le callback, service 01 running...");
});
service01.setOnSucceeded(event -> {
System.out.println("par le callback, service 01, etat, success");
});
service01.setOnFailed(event -> {
System.out.println("par le callback, service 01, etat, failed");
System.err.println("echec du service");
service01.getException().printStackTrace();
});
service01.setOnCancelled(event -> {
System.out.println("par le callback, service 01, etat, cancelled");
});
// --------------------------------------------------------
// demarrer l'instance de Service
// la variable portée class
// prend la valeur de la variable portée locale
serviceB = service01;
// on demarre l'instance service de Service
serviceB.start();
}现在，我需要找到如何返回2个进程。
