Question

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的专家。我必须处理一个遗留项目。这是一个Netbeans平台应用程序，有几个模块。据我所知，在启动期间，该类将是-let's say' - 主类，它扩展了ModuleInstall。通常这个类的名称是Installer。

我的问题是，我有这个扩展ModuleInstall的Installer类，它实现了所有必需的方法，但是如果我启动项目，则会出现其他窗口而不是这个窗口。

你知道我该怎么做才能在开始时调用正确的类吗？

提前致谢！

Answer 1

这里是你问题的答案（尽管我看到你以不同的方式解决了它）。

但是，我想回答你的问题：

有没有办法设置我启动时应该启动哪个类 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方法类。

通过在启动应用程序时在命令行上提供系统属性netbeans.mainclass来执行此操作。这必须指向您的自定义主类。定义此变量的位置位于应用程序的conf文件中。

一旦您在自定义主服务器中执行了任何您想要执行的操作，就必须将控制权移交给真正的NetBeans主类。

以下是此类自定义主程序的简短示例：

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);
    }
}

很好地解释了here。（例子来自该链接）

Answer 2

Ctrl-1 打开项目窗口
右键点击项目中的，然后点击属性
点击左侧类别窗格中的运行节点，在右侧查找主类：文本字段，然后输入主类的完全限定名称，或者您只需单击浏览... 按钮即可避免拼写错误。

如果是Maven项目，请确保pom.xml元素中的/project/build/plugins包含以下内容：
