[英]JavaFX Application Thread - When using Gluon Ignite Dependency Injection
我使用的是Gluon的Ignite依赖项注入库,运行此代码时出现以下错误。
public void initialize() {
Platform.runLater(() -> {
ApplicationContext context = new ClassPathXmlApplicationContext(this.getClass().getResource("DL4JBeans.xml").getPath());
dL4JData = context.getBean("dL4JData", DL4JData.class);
dL4JGlobalConfig = context.getBean("dL4JGlobalConfig", DL4JGlobalConfig.class);
dL4JLayers = context.getBean("dL4JDataLayers", DL4JLayers.class);
dL4JModel = context.getBean("dL4JModel", DL4JModel.class);
((ClassPathXmlApplicationContext) context).close();
});
}
错误日志:

这是第140行。
ApplicationContext context = new ClassPathXmlApplicationContext(this.getClass().getResource("DL4JBeans.xml").getPath());
它没有给出“文件未找到”异常,只有“线程应用程序”错误。 这是我的gradle文件。
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.3.17'
}
}
apply plugin: 'org.javafxports.jfxmobile'
repositories {
jcenter()
maven {

}
}

// Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead

}

manifest = 'src/android/AndroidManifest.xml'
}
ios {
infoPList = file('src/ios/Default-Info.plist')
forceLinkClasses = [

]
}
}
一件奇怪的事情是,即使遇到这些错误,我仍然可以使用刚注入的依赖项中的方法。
这是我的文件夹结构的图像:
更新:
如果找不到资源,则getResource()
返回null
。 我敢打赌,它找不到DL4JBeans.xml。
DL4JBeans.xml应该是
