NetBeans平台应用程序主类没有'；开始

在启动NetBeans平台应用程序时，有没有办法设置应该启动哪个类？不幸的是，我不是Netbeans专家。 我必须处理一个遗留项目。这是一款具有多个模块的Netbeans平台应用程序。据我所知，在启动过程中，该类将是（比方说）主类，它扩展了ModuleInstall。通常，此类的名称为Installer

我的问题是，我有一个扩展了ModuleInstall的安装程序类，它实现了所有必需的方法，但是如果我启动项目，就会出现另一个窗口而不是这个窗口

你知道我应该怎么做才能在一开始调用正确的类吗

提前谢谢

以下是您问题的答案（尽管我发现您的解决方式有所不同）

不过，我想回答你目前的问题：

当我启动一个新的类时，有没有办法设置应该启动哪个类 NetBeans平台应用程序

是的，有。您可以为NetBeans平台应用程序提供自己的

main

method类

您可以通过在启动应用程序时在命令行上提供一个系统属性，

netbeans.mainclass

。这必须指向您的自定义主类。定义此变量的位置在应用程序的

conf

文件中

一旦您在自定义main中完成了任何您想做的事情，那么您必须将控制权移交给真正的NetBeans主类

下面是这样一个自定义干管的简短示例：

public class CustomStartup {

    private static final String NB_MAIN_CLASS = "org.netbeans.core.startup.Main";

    public static void main(String[] args) throws Exception {
        // do whatever you need here (e.g. show a custom login form)
        System.out.println("Hello world! I am a custom startup class");


        // once you're done with that, hand control back to NetBeans
        ClassLoader classloader = Thread.currentThread().getContextClassLoader();
        Class<?> mainClass = Class.forName(NB_MAIN_CLASS, true, classloader);

        Object mainObject = mainClass.newInstance();
        Method mainMethod = mainClass.getDeclaredMethod("main", new Class[]{String[].class});
        mainMethod.invoke(mainObject, (Object) args);
    }
}

公共类自定义启动{
私有静态最终字符串NB_MAIN_CLASS=“org.netbeans.core.startup.MAIN”；
公共静态void main（字符串[]args）引发异常{
//在此处执行任何需要的操作（例如，显示自定义登录表单）
System.out.println（“你好，世界！我是一个自定义的启动类”）；
//完成后，将控制权交回NetBeans
ClassLoader ClassLoader=Thread.currentThread（）.getContextClassLoader（）；
Class mainClass=Class.forName（NB_MAIN_Class，true，classloader）；
Object mainObject=mainClass.newInstance（）；
方法mainMethod=mainClass.getDeclaredMethod（“main”，新类[]{String[].Class}）；
调用（mainObject，（Object）参数）；
}
}

这是很好的解释。（示例来自该链接）

谢谢您的回答，但这不是我想要的。您在回答中介绍的是如何在Java应用程序中设置主类。对于Netbeans平台应用程序，我需要类似的东西，这是不同的。对于此类项目，实际的主类位于运行时容器内。我必须告诉运行时容器我想启动哪个类@高科技黑手: 很好的截图！您使用了哪种工具制作它？[Alt+PrintScreen]并粘贴到GIMP（www.GIMP.org），使用“椭圆选择工具”选择我要高亮显示的区域，然后使用[Ctrl+I]（选择->反转）反转选择，最后变灰（颜色->去饱和）；希望这对您有所帮助：）您想要实现什么，在启动时显示一些Swing组件或执行其他操作？现在你的安装程序类没有启动？你使用哪个版本的Netbeans平台？我最终解决了这个问题。问题是，我试图使用最新版本的netbeans，而项目是使用较旧版本的netbeans（7.2）创建的。我要做的是用正确版本的Netbeans打开项目并编译它。
