- public Scheduler getScheduler() {
- return scheduler;
- }

- this.scheduler = scheduler;
- }
- }
注意事项:
1、SchedulerFactoryBean 在spring.xml配置了,但不能直接注入,就算加上@Component注解也不行,所以使用SpringUtils 工具类获取。
Xml代码
- <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
2、获取到的SchedulerFactoryBean 并不是SchedulerFactoryBean,而是scheduler
Java代码
- private Scheduler scheduler = (Scheduler) SpringUtils.getBeanById("scheduler");
二、ScheduleJob 类:可以保存计划任务的信息,也可以做为实体参数
Java代码
- public class ScheduleJob implements Serializable{
- private Long scheduleJobId;
- /** 任务名称 */
- private String jobName;
- /** 任务分组 */
- private String jobGroup;
- /** 定时任务对应的类(包括包路径),如:cn.imovie.manage.task.job.TicketMoneyLessThanNormalWarn */
- private String clazz;
- /** 任务状态:1禁用 2启用 3删除*/
- private String jobStatus;
- /** 任务运行时间表达式 */
- private String cronExpression;
- /** 任务描述 */
- private String jobDesc;
- private Long createMan;
- private Date createTime;
- private Long updateMan;
- private Date updateTime;
- // 非持久化属性
- private String createManText;
- private String updateManText;
- public Long getScheduleJobId() {
- return scheduleJobId;
- }
- public void setScheduleJobId(Long scheduleJobId) {
- this.scheduleJobId = scheduleJobId;
- }
- public String getJobName() {
- return jobName;
- }
- public void setJobName(String jobName) {
- this.jobName = jobName;
- }
- public String getJobGroup() {
- return jobGroup;
- }
- public void setJobGroup(String jobGroup) {
- this.jobGroup = jobGroup;
- }
- public String getClazz() {
- return clazz;
- }
- public void setClazz(String clazz) {
- this.clazz = clazz;
- }
- public String getJobStatus() {
- return jobStatus;
- }
- public void setJobStatus(String jobStatus) {
- this.jobStatus = jobStatus;
- }
- public String getCronExpression() {
- return cronExpression;
- }
- public void setCronExpression(String cronExpression) {
- this.cronExpression = cronExpression;
- }
- public String getJobDesc() {
- return jobDesc;
- }
- public void setJobDesc(String jobDesc) {
- this.jobDesc = jobDesc;
- }
- public Long getCreateMan() {
- return createMan;
- }
- public void setCreateMan(Long createMan) {
- this.createMan = createMan;
- }
- public Date getCreateTime() {
- return createTime;
- }
- public void setCreateTime(Date createTime) {
- this.createTime = createTime;
- }
- public Long getUpdateMan() {
- return updateMan;
- }
- public void setUpdateMan(Long updateMan) {
- this.updateMan = updateMan;
- }
- public Date getUpdateTime() {
- return updateTime;
- }
- public void setUpdateTime(Date updateTime) {
- this.updateTime = updateTime;
- }
- @Transient
- public String getCreateManText() {
- return createManText;
- }
- public void setCreateManText(String createManText) {
- this.createManText = createManText;
- }
- @Transient
- public String getUpdateManText() {
- return updateManText;
- }
- public void setUpdateManText(String updateManText) {
- this.updateManText = updateManText;
- }
- }
三、Spring.xml 文件配置
Xml代码
- <!-- 定时任务配置 start -->
- <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
- <property name="dataSource" ref="dataSource"></property>
- <!--可选,QuartzScheduler 启动时更新己存在的Job,这样就不用每次修改targetObject后删除qrtz_job_details表对应记录了 -->
- <property name="overwriteExistingJobs" value="true" />
- <!--必须的,QuartzScheduler 延时启动,应用启动完后 QuartzScheduler 再启动 -->
- <property name="startupDelay" value="10" />
- <!-- 设置自动启动 -->
- <property name="autoStartup" value="true" />
- <property name="applicationContextSchedulerContextKey" value="applicationContextKey" />
- <property name="configLocation" value="classpath:spring-quartz.properties" />
- </bean>
- <bean id="schedulerManage" class="cn.imovie.manage.task.SchedulerManage"></bean>
- <!-- 定时任务配置 end -->
四、spring-quartz.properties 文件配置:
Java代码
- #配置见:http://www.quartz-scheduler.org/documentation/quartz-2.2.x/configuration/ConfigJDBCJobStoreClustering.html
- #============================================================================
- # Configure Main Scheduler Properties
- #============================================================================
- org.quartz.scheduler.instanceName = MyClusteredScheduler
- org.quartz.scheduler.instanceId = AUTO
- #============================================================================
- # Configure ThreadPool
- #============================================================================
- org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
- org.quartz.threadPool.threadCount = 25
- org.quartz.threadPool.threadPriority = 5
- #============================================================================
- # Configure JobStore
- #============================================================================
- org.quartz.jobStore.misfireThreshold = 60000
- org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
- org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
- org.quartz.jobStore.useProperties = false
- org.quartz.jobStore.dataSource = myDS
- org.quartz.jobStore.tablePrefix = QRTZ_
- org.quartz.jobStore.isClustered = true
- org.quartz.jobStore.clusterCheckinInterval = 20000
