java呼叫第三方應用程式

1. java呼叫第三方應用使用 ProcessBuilder 物件來呼叫
例子位置:
xc-service-manage-media-processor/test/TestProcessBuilder
//建立processBuilder物件
ProcessBuilder processBuilder = new ProcessBuilder();
//設定第三方應用程式的命令
// processBuilder.command("ping","127.0.0.1");
processBuilder.command("ipconfig");
//將標準輸入流和錯誤流合併
processBuilder.redirectErrorStream(true);
//啟動一個程序(相當於在命令列中輸入命令)
Process process = processBuilder.start();
//通過標準輸入流來拿到正常和錯誤的資訊
InputStream inputStream = process.getInputStream();
//轉成字元流
InputStreamReader reader = new InputStreamReader(inputStream,"gbk");
//緩衝
char[] chars = new char[1024];
int len = -1;
while ((len = reader.read(chars))!=-1){
String string = new String(chars,0,len);
System.out.println(string);
}
inputStream.close();
reader.close();
