Selenium Grid 4 - Code(Hub)

1.主入口

1)main方法 [class: org/openqa/selenium/grid/Main.java]

public static void main(String[] args) {
    // Bruce Notes: args is required like: standalone, hub...
    new Main(System.out, System.err, args).go();
  }

2)调用go方法

void go() {
    // It's not private to make it visible for tests
    if (args.length == 0) {
      showHelp(Main.class.getClassLoader());
    } else {
      launch(args, Main.class.getClassLoader());
    }
}

3)launch方法

private void launch(String[] args, ClassLoader loader) {
    String commandName = args[0];
    String[] remainingArgs = new String[args.length - 1];
    System.arraycopy(args, 1, remainingArgs, 0, args.length - 1);

    Set<CliCommand> commands = loadCommands(loader);

    CliCommand command = commands.parallelStream()
        .filter(cmd -> commandName.equals(cmd.getName()))
        .findFirst()
        .orElse(new Help(commands));

    command.configure(out, err, remainingArgs).run();
}
