问使用PumpStreamHandler将输出和错误写入日志文件

EN

class ExecLogHandler extends LogOutputStream {
    private Logger log;

    public ExecLogHandler(Logger log, Level logLevel) {
        super(logLevel.toInt());
        this.log = log;
    }

    @Override
    protected void processLine(String line, int logLevel) {
        log.log(Level.toLevel(logLevel), line);
    }
}

public static int executeCommand(CommandLine command, Logger log) throws ExecuteException, IOException {
    DefaultExecutor executor = new DefaultExecutor();
    executor.setExitValue(0);

    PumpStreamHandler psh = new PumpStreamHandler(new ExecLogHandler(log, Level.DEBUG), new ExecLogHandler(log, Level.ERROR));
    executor.setStreamHandler(psh);

    return executor.execute(command);
}
