我目前有一个使用命令行和参数运行 FIO 命令的程序。但它不会获取命令的完整输出，并且还会等待线程完成，然后再将任何内容打印到 GUI（不会冻结 GUI）。
public static String test_buffer(ArrayList<String> drives, int numJobs, int fileSize, int runtime, String byte_size) {
String[] filenames = drives.stream()
.map(diskName -> diskName.replaceAll("[^\\d]", ""))
.map(diskName -> "--filename=\\\\.\\PhysicalDrive" + diskName)
.toArray(String[]::new);
String command = "C:\\Program Files\\fio\\fio.exe "
+ "--name=test "
+ "--bs=" + byte_size + " "
+ "--rw=read "
+ "--numjobs=" + numJobs + " "
+ "--size=" + fileSize + "g "
+ "--direct=1 "
+ "--runtime=" + runtime + " "
+ "--iodepth=16 "
+ "--eta-newline=1 "
+ String.join(" ", filenames);
ExecutorService executor = Executors.newSingleThreadExecutor();
StringBuilder output = new StringBuilder();
objMargay_Controller.IO_TEXT_FIELD.setText(command + "\n");
try {
Process process = Runtime.getRuntime().exec(command);
PipedOutputStream outputStream = new PipedOutputStream();
PipedInputStream inputStream = new PipedInputStream(outputStream);
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
executor.submit(() -> {
try {
String line;
while ((line = reader.readLine()) != null) {
output.append(line).append("\n");
Log.IO_LOG(Programming.SAS_ADDR, line);
String finalLine = line;
Platform.runLater(() -> {
objMargay_Controller.IO_TEXT_FIELD.appendText(finalLine + "\n");
objMargay_Controller.IO_TEXT_FIELD.positionCaret(objMargay_Controller.IO_TEXT_FIELD.getLength());
objMargay_Controller.IO_TEXT_FIELD.setScrollTop(Double.MAX_VALUE);
});
}
} catch (IOException e) {
e.printStackTrace();
}
});
byte[] buffer = new byte[8192];
int read;
while ((read = process.getInputStream().read(buffer)) != -1) {
outputStream.write(buffer, 0, read);
}
process.waitFor();
} catch (Exception e) {
e.printStackTrace();
}
executor.shutdown();
return output.toString();
}
我的 GUI 中的输出给了我这个：
