Quartz与Spring集成（二）

一、获取quartz详情jar

<!-- quartz 的jar -->
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.2.1</version>
</dependency>
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz-jobs</artifactId>
    <version>2.2.1</version>
</dependency>

二、相关代码案例

一个job可以有多个处罚

一个触发只能有一个job

//Main.java启动类
public class Main {

    public static void main(String[] args) {
        new ClassPathXmlApplicationContext("classpath:applicationContext-scheduler.xml");
    }
}

//MyJob任务类
public class MyJob extends QuartzJobBean {

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {

        System.out.println("myJob执行了............" + context.getTrigger().getKey().getName());
        ApplicationContext applicationContext = (ApplicationContext) context.getJobDetail().getJobDataMap()
                .get("applicationContext");
        System.out.println("获取到的Spring容器是" + applicationContext);
    }

}

//applicationContext-scheduler.xml

            </list>
        </property>
