Quartz 定时器任务调度

Job：是一个接口只有一个方法void execute(JobExecutionContext context)，开发者实现该接口定义运行任务，JobExecutionContext类提供了调度上下文的各种信息。Job运行时的信息保存在JobDataMap实例中

第一种，作业类继承自特定的基  1.8测试成功，2.0不行类：org.springframework.scheduling.quartz.QuartzJobBean。

java类代码

package com.ncs.hj;  import java.util.Date;import org.quartz.JobExecutionContext;  import org.quartz.JobExecutionException;  import org.springframework.scheduling.quartz.QuartzJobBean;  public class SpringQtz extends QuartzJobBean{      private static int counter = 0;      protected void executeInternal(JobExecutionContext context) throws JobExecutionException {           System.out.println(Thread.currentThread().getName());        long ms = System.currentTimeMillis();          System.out.println( new Date(ms));          System.out.println(ms);          System.out.println("(" + counter++ + ")");          String s = (String) context.getMergedJobDataMap().get("service");          System.out.println(s);           }  }

spring配置文件

第二种，作业类不继承特定基类。1.8和2.0均测试成功, spring 4以上版本

java类

    package com.ncs.hj;                  import java.util.Date;            public class SpringQtz2 {          private static int counter = 0;          protected void execute()  {              System.out.println(Thread.currentThread().getName());            long ms = System.currentTimeMillis();              System.out.println( new Date(ms));                          System.out.println("(" + counter++ + ")");          }      }

quartz默认是多线程的
