Spring整合Quartz_an error occurred instantiating job to be executed-优快云博客

本文介绍如何使用Spring框架整合Quartz实现定时任务的配置与执行。通过定义实体类ScheduleJob来封装Job信息，利用PlanJob类实现Job接口执行具体任务，并通过JobService进行业务调用。spring配置文件中详细展示了如何配置JobDetail、CronTrigger和SimpleTrigger，以及Scheduler的初始化过程。

1、jar

spring基础包(spring-context-support.jar/spring-tx.jar)+quartz

2、整个配置信息

a.将Job信息封装到一个实体类中 //spring 约定

public class ScheduleJob {
    //id
    private String jobId;
    private String jobName;//名
    private String jobGroup;//组
//    前面必须写
    private String jobStatus; //状态 0  禁用 1 启用 2 删除
    private String cronExpression;//Cron表达式
    private String desc;//描述
}

其他相关的类

public class PlanJob implements Job {
    private JobService jobService = new JobService();
    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        TriggerKey key = jobExecutionContext.getTrigger().getKey();
        JobKey key1 = jobExecutionContext.getJobDetail().getKey();
        System.out.println(key +":"+key1);
        jobService.callWorking();
    }
}

public class JobService {
    public void callWorking(){
        System.out.println("该工作了。。。。。");
    }
}

b.spring配置文件

application.xml

<bean id="job" class="org.springAndQuartz.entity.ScheduleJob">
    <property name="jobId" value="job001"/>
    <property name="jobName" value="任务一"/>
    <property name="jobGroup" value="任务组-"/>
    <property name="jobStatus" value="1"/>
    <property name="cronExpression" value="5,10,20 * * * * ? *"/>
    <property name="desc" value="描述。。。。"/>
</bean>
<bean id="jobDetail"  class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
    <property name="jobClass" value="org.springAndQuartz.job.PlanJob" >
    </property>
    <property name="jobDataAsMap">
        <map>
            <entry key="scheduleJob">
               <ref bean="job"></ref>
            </entry>
        </map>
    </property>
</bean>
<!--触发器-->
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="cronExpression" value="#{job.cronExpression}"/>
    <property name="jobDetail" ref="jobDetail"/>
    <property name="name" value="#{job.jobName}"/>
    <property name="group" value="#{job.jobGroup}"/>
</bean>
<bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
    <property name="repeatInterval" value="1000"/>
    <property name="jobDetail" ref="jobDetail"/>
    <property name="repeatCount" value="10"/>
    <property name="name" value="#{job.jobName}"/>
    <property name="group" value="#{job.jobGroup}"/>
</bean>

<!--调度器-->
<bean id="stdScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="simpleTrigger"></ref>
        </list>
    </property>
</bean>

test

public class Test {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        //可以自动执行 
        //原因 ： springIOC容器 自动初始化  默认 autoStartup        
    }
}
