使用 ProcessBuilder 

 

List<String> commands = new ArrayList();        commands.add("python");        commands.add("/Users/yangkun/workSpace/task/task/odsdata/etl_task/etl_task.py");        commands.add("-id");        commands.add(id);        ProcessBuilder processBuilder = new ProcessBuilder(commands);        Map<String, String> env = processBuilder.environment();        env.put("PYTHONPATH","/Users/yangkun/workSpace/sss/");        try {            processBuilder.start();        } catch (IOException e) {            e.printStackTrace();        }

 

ProcessBuilder pb = new ProcessBuilder("python", "/Users/yangkun/workSpace/sss/task/odsdata/etl_task/etl_task.py","-id","1111");        Map<String, String> env = pb.environment();        env.put("PYTHONPATH","/Users/yangkun/workSpace/sss/");        for (String s : env.keySet()) {            System.out.println("key:"+ s + "  :  "+ env.get(s));        }        try {            pb.start();        } catch (IOException e) {            e.printStackTrace();        }
