apache.commons.exec 라이브러리 사용하기

apache.commons.exec : 외부 실행 파일을 간편하게 실행하게 해주는 라이브러리

1. 라이브러리 다운로드

  1.1. https://commons.apache.org/proper/commons-exec/ 접속하여 Download 클릭

  1.2. commons-exec.1.3.bin.zip 클릭하여 다운로드

2. 예제

  2.1. 아크로뱃을 실행

String line = "AcroRd32.exe /p /h " + file.getAbsolutePath();  CommandLine cmdLine = CommandLine.parse(line);  DefaultExecutor executor = new DefaultExecutor();  executor.setExitValue(1);  int exitValue = executor.execute(cmdLine);

  2.2. Watchdog 이용

String line = "AcroRd32.exe /p /h \"" + file.getAbsolutePath() + "\"";  CommandLine cmdLine = CommandLine.parse(line);  DefaultExecutor executor = new DefaultExecutor();  executor.setExitValue(1);  ExecuteWatchdog watchdog = new ExecuteWatchdog(60000);  executor.setWatchdog(watchdog);  int exitValue = executor.execute(cmdLine);

  2.3. CommandLine Build 이용

Map map = new HashMap();  map.put("file", new File("invoice.pdf"));  CommandLine cmdLine = new CommandLine("AcroRd32.exe");  cmdLine.addArgument("/p");  cmdLine.addArgument("/h");  cmdLine.addArgument("${file}");  cmdLine.setSubstitutionMap(map);  DefaultExecutor executor = new DefaultExecutor();  executor.setExitValue(1);  ExecuteWatchdog watchdog = new ExecuteWatchdog(60000);  executor.setWatchdog(watchdog);  int exitValue = executor.execute(cmdLine);

  2.4. 비동기적으로 실행

CommandLine cmdLine = new CommandLine("AcroRd32.exe");  cmdLine.addArgument("/p");  cmdLine.addArgument("/h");  cmdLine.addArgument("${file}");  HashMap map = new HashMap();  map.put("file", new File("invoice.pdf"));  commandLine.setSubstitutionMap(map);  DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();  ExecuteWatchdog watchdog = new ExecuteWatchdog(60*1000);  Executor executor = new DefaultExecutor();  executor.setExitValue(1);  executor.setWatchdog(watchdog);  executor.execute(cmdLine, resultHandler);  // some time later the result handler callback was invoked so we  // can safely request the exit value  int exitValue = resultHandler.waitFor();
