方法1

    public static void exec() throws IOException, InterruptedException {
        CommandLine cmdLine = CommandLine.parse("sh aa.sh");
        ExecuteWatchdog watchdog = new ExecuteWatchdog(60 * 1000);
        DefaultExecutor executor = new DefaultExecutor();
        executor.setWorkingDirectory(new File("/Users/chenshun/open/example-demo/springcloud-provider/src/main/resources/shell"));
        StringBuilder ss = new StringBuilder();
        PumpStreamHandler streamHandler = new PumpStreamHandler(new LogOutputStream() {
            @Override
            protected void processLine(String line, int logLevel) {
                ss.append(line).append("\n\r");
                System.out.println("SS logLevel:" + logLevel);
            }
        });
        executor.setStreamHandler(streamHandler);
        executor.setExitValue(0);
        executor.setWatchdog(watchdog);
        System.out.println(cmdLine);
        final int execute = executor.execute(cmdLine);
        System.out.println("结束码:" + execute);
        System.out.println("正常的:" + ss.toString());
    }

方法2

public static void exec2() throws Exception {
    final ProcessResult execute = new ProcessExecutor().command("/usr/local/bin/wkhtmltopdf", "https://zhuanlan.zhihu.com/p/425702746", "/Users/chenshun/Desktop/XrkrnMeAy.pdf")
        .readOutput(true)
        .execute();
    final int exitValue = execute.getExitValue();
    System.out.println("exit:" + exitValue);
    final ProcessOutput output = execute.getOutput();
    for (String line : output.getLines()) {
        System.out.println(line);
    }
}
public static void exec3() throws Exception {
    final ProcessResult execute = new ProcessExecutor().command("sh", "aa.sh")
            .readOutput(true)
            .directory(new File("/Users/chenshun/open/example-demo/springcloud-provider/src/main/resources/shell"))
            .execute();
    final int exitValue = execute.getExitValue();
    System.out.println("exit:" + exitValue);
    final ProcessOutput output = execute.getOutput();
    for (String line : output.getLines()) {
        System.out.println(line);
    }
}
