我正在构建一个工具,它应该通过Windows命令提示符从格式A转换为格式B.我编程了一些像交互模式的东西。 cmd等待输入命令并处理它们。 现在我想通过一些参数,如果我打电话给程序。参数将被传递,但程序不会自行执行命令。自动执行args程序
我传递ARGS这样的:
java -jar test.jar -interactive //activates the interactive mode, which does not make any problems
和这样的(通过源文件,在转换过程中所使用的目标的地方保存转换后的文件,目标格式和最后配置文件):
java -jar test.jar C:\Users\User\Desktop\test.json C:\Users\User\Desktop .xes C:\Users\User\Desktop\test.properties
代码到目前为止:
public static void main(final String[] args) throws IOException, InterruptedException {
if (args[0].equals("-interactive")) {
testing test = new testing();
test.startCMD();
} else if (args[0] != null && args[1] != null && args[2] != null && args[3] != null) {
final testing test = new testing();
test.startCMD();
//the following construct doesn't work unfortunatelly
worker = Executors.newSingleThreadScheduledExecutor();
Runnable task = new Runnable() {
@Override
public void run() {
test.setSourceFile(args[0]);
test.setTargetPath(args[1]);
test.setTargetFormat(args[2]);
test.setConfigFilePath(args[3]);
System.out.println("Invoking the conversion routine now ...");
ConverterControl control = new ConverterControl();
control.link(sourceFilePath, targetPath, configFilePath, targetFormat, fileConfig);
}
};
worker.schedule(task, 5, TimeUnit.SECONDS);
}
}
public void startCMD() throws IOException, InterruptedException {
String[] command
= {
"cmd",};
Process p = Runtime.getRuntime().exec(command);
new Thread(new SyncPipe(p.getErrorStream(), System.err)).start();
new Thread(new SyncPipe(p.getInputStream(), System.out)).start();
BufferedReader in = new BufferedReader(
new InputStreamReader(System.in));
System.out.println("Welcome to the Windows command line prompt." + System.lineSeparator());
System.out.println("Please type \"help\" to receive a list of commands available in this environment.");
//String s = in.readLine();
String input;
while ((input = in.readLine()) != null) {
//process the inputs
}
您在main方法中看到的不同setter
只是将传递的信息设置为声明在类顶部的变量。之后这些变量应该被传递给ConverterControl
,它在其link()
方法中具有整个转换例程。 执行startCMD()
命令后,如果我传递4个参数(请参阅顶部程序的第二个调用),程序将停止。
有谁知道如何调用这些方法并自动启动ConverterControl
?
