动态定义quartz定时任务

记录自己写的代码，肯定有不对的地方，参阅的话仅供参考。
这个用的是quartz-2.2.2.jar版本，动态设置了定时任务。

public class TaskManager {    private static  TaskManager instance ;    private SchedulerFactory schedFact = new org.quartz.impl.StdSchedulerFactory();    private TaskManager(){};    public static TaskManager getInstance(){        if(instance == null) instance = new TaskManager();        return instance;    }    //添加job    public void addJob(String jobName,String serviceName,String cronExpression,Map contextMap) throws Exception{        Scheduler sched = schedFact.getScheduler();         if(!sched.isStarted()) sched.start();        JobDetail jobDetail = newJob(TaskJob.class)                .withIdentity(jobName, Scheduler.DEFAULT_GROUP)                .usingJobData("serviceName", serviceName)                .build();        for(Object key : contextMap.keySet()){            jobDetail.getJobDataMap().put(key.toString(), contextMap.get(key));        }        Trigger trigger = newTrigger()                .withIdentity(jobName+"Trigger", Scheduler.DEFAULT_GROUP)                .withSchedule(cronSchedule(cronExpression))                .forJob(jobDetail)                .build();        sched.scheduleJob(jobDetail, trigger);    }    //添加job    public void addJob(String jobName,String serviceName,String cronExpression) throws Exception{        Scheduler sched = schedFact.getScheduler();         if(!sched.isStarted())  sched.start();        JobDetail jobDetail = newJob(TaskJob.class)                .withIdentity(jobName, Scheduler.DEFAULT_GROUP)                .usingJobData("serviceName", serviceName)                .build();        Trigger trigger = newTrigger()                .withIdentity(jobName+"Trigger", Scheduler.DEFAULT_GROUP)                .withSchedule(cronSchedule(cronExpression))                .forJob(jobDetail)                .build();        sched.scheduleJob(jobDetail, trigger);    }    //移除job    public void removeJob(String jobName) throws Exception{        Scheduler sched = schedFact.getScheduler();         if(!sched.isStarted()) sched.start();        sched.unscheduleJob(triggerKey(jobName + "Trigger", Scheduler.DEFAULT_GROUP));        sched.deleteJob(jobKey(jobName, Scheduler.DEFAULT_GROUP));    }}

下面是要执行的job，写任务的逻辑

public class TaskJob implements Job {    @Override    public void execute(JobExecutionContext context) throws JobExecutionException {        JobDataMap dataMap = context.getJobDetail().getJobDataMap();                String serviceName = dataMap.getString("serviceName");        System.out.println(serviceName);    }}

下面是测试

public class TaskTest {    public static void main(String[] args) throws Exception {        TaskManager mm = TaskManager.getInstance();        for(int i=0;i<5;i++){            mm.addJob("测试"+i,"服务"+i, "0/10 * * * * ?");        }        Thread.sleep(100000);    }}

哦对，时间解析，我写了个简单的，仅供参考

public String transform(String month,String day,String week){          //month 范围 1-12 即1-12月        //day 范围1-31 即1-31日 注意特殊月份2月28天 最好1-28        //week 范围MON-SUN        String result="";        if (week==null || week.equals("")) { //week 每周一次 ，他选其他都必须为null            if (month==null || month.equals("")) {                 if (day==null || day.equals("")) {                    result=DAY;                }else{                result="0 0 1 "+day+" * ?";                }            }else {                result="0 0 1 "+day+" "+month+" ?";            }        }else{            result="0 0 1 ? * "+week; //每周一次        }        return result;    }
