Java 执行jar linux 实例

需求：通过执行jar的方式 ，把某个文件路径下的用户数据同步到redis

  1、main 函数

public class Main {

    private static Logger logger = LoggerFactory.getLogger(Main.class);

    private static DisruptorService disruptorService = new DisruptorService();

    private static AppsTaskService appsTaskService =new AppsTaskService();

    /**
     * 调用具体的方法
     * @param args
     */
    public static void main (String[] args) {
        try {
            if(args[0].trim().equals("appsTask")){

                appsTaskService.appsTask(args[1],args[2]);
            }else{
                Method targetMethod = DisruptorService.class.getDeclaredMethod(args[0].trim(), args.getClass());
                targetMethod.invoke(disruptorService, (Object)args);
            }
        } catch (Exception e) {
            e.printStackTrace();
            logger.error(e.getMessage());
        }
    }

}
