关于javaFX的窗口启动问题

[weixin_38068392]

为什么Stage必须写start里呢?我写main方法里不行吗? java虚拟机为什么报了个这个错误呢? java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.sun.javafx.application.LauncherImpl.launchApplicationWithArgs(LauncherImpl.java:389) at com.sun.javafx.application.LauncherImpl.launchApplication(LauncherImpl.java:328) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at sun.launcher.LauncherHelper$FXHelper.main(LauncherHelper.java:767) Caused by: java.lang.IllegalStateException: Not on FX application thread; currentThread = main at com.sun.javafx.tk.Toolkit.checkFxUserThread(Toolkit.java:279) at com.sun.javafx.tk.quantum.QuantumToolkit.checkFxUserThread(QuantumToolkit.java:423) at javafx.stage.Stage.<init>(Stage.java:241) at javafx.stage.Stage.<init>(Stage.java:227) at lesson3.Main.main(Main.java:13) ... 11 more Exception running application lesson3.Main

因为你采用了javafx技术，这个并不是普通的java框架，你要启动程序就需要遵照javafx 的技术要求啊！！
