Java调用脚本并输出脚本返回数据

2019独角兽企业重金招聘Python工程师标准>>>

public class ExecuteSHFile {
	private static Logger logger = LoggerFactory.getLogger(ExecuteSHFile.class);
	
	public static String executeSHFile(String shutdown_path) throws Exception {
		//执行XXX.sh脚本
		Process ps = Runtime.getRuntime().exec("sh "+shutdown_path);
		//阻塞，直到上述命令执行完成，当返回值为0时表示执行成功
		int resultCode = ps.waitFor();
		String result=null;
		logger.info("resultCode"+resultCode);
		if(resultCode == 0){
            //只能接收脚本echo打印的数据，并且是echo打印的最后一次数据
			BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));
			StringBuffer sb = new StringBuffer();
			String line = br.readLine();
			while(line != null){
				logger.info(line);
				line = br.readLine();
				sb.append(line).append("\n");
			}
			result = sb.toString();
		} else {
			logger.info("resultCode 不是0，线程没有正常结束 ========== " + resultCode);
		}
		return result;
	}
}

 jdk自带的runtime类里有相关的实现方法。

• //可以执行脚本

• String command = "/usr/local/transStr.sh";

• //可以执行命令

• String command = "ps -ef|grep java";

• //可以执行带参数的脚本

• String[] command = {"/usr/local/transStr.sh", "test"};

• Process ps = Runtime.getRuntime().exec(command);
