代码如下：
DateTime dateTime = DateTime.parse(GlobalVariables.END_TIME_STRING,
DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss")).minusMinutes(30).plusSeconds(5);
String jobCronExp = TimeUtil.formaterCronExpression(dateTime);
System.out.println("job cron expression: " + jobCronExp);
Cron4jPlugin cron4jPlugin = new Cron4jPlugin();
cron4jPlugin.add(jobCronExp, new ForceRefreshRankTask());
me.add(cron4jPlugin);ForceRefreshRankTask.java
public class ForceRefreshRankTask implements Runnable {
private Logger logger = LoggerFactory.getLogger(ForceRefreshRankTask.class);
@Override
public void run() {
logger.info("强制执行前台排行榜刷新任务！");
QuestionUtil.pushRank();
}
}然后错误：
