在spring boot中使用quartz时，在job中一般需要引用spring管理的bean，通过定义job factory实现自动注入。

spring有自己的schedule定时任务，在spring boot中使用的时候，不能动态管理job，于是就使用quartz来实现。

在spring boot中配置quartz：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 import java.io.ioexception; import java.util.properties; import org.springframework.beans.factory.annotation.autowired; import org.springframework.beans.factory.config.propertiesfactorybean; import org.springframework.context.annotation.bean; import org.springframework.context.annotation.configuration; import org.springframework.core.io.classpathresource; import org.springframework.scheduling.annotation.enablescheduling; import org.springframework.scheduling.quartz.schedulerfactorybean; @configuration @enablescheduling public class quartzschedule { @autowired private myjobfactory myjobfactory; @bean public schedulerfactorybean schedulerfactorybean() throws ioexception { schedulerfactorybean factory = new schedulerfactorybean(); factory.setoverwriteexistingjobs(true); // 延时启动 factory.setstartupdelay(20); // 加载quartz数据源配置 factory.setquartzproperties(quartzproperties()); // 自定义job factory，用于spring注入 factory.setjobfactory(myjobfactory); return factory; } /** * 加载quartz数据源配置 * * @return * @throws ioexception */ @bean public properties quartzproperties() throws ioexception { propertiesfactorybean propertiesfactorybean = new propertiesfactorybean(); propertiesfactorybean.setlocation(new classpathresource("/quartz.properties")); propertiesfactorybean.afterpropertiesset(); return propertiesfactorybean.getobject(); } }

为了在job中使用spring管理的bean，需要重新定义一个job factory：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 @component public class myjobfactory extends adaptablejobfactory { @autowired private autowirecapablebeanfactory capablebeanfactory; @override protected object createjobinstance(triggerfiredbundle bundle) throws exception { // 调用父类的方法 object jobinstance = super.createjobinstance(bundle); // 进行注入 capablebeanfactory.autowirebean(jobinstance); return jobinstance; } }

然后在job中就可以使用spring管理的bean了

? 1 2 3 4 5 6 7 8 9 10 11 12 public class myjob implements job, serializable { private static final long serialversionuid = 1l; private logger logger = loggerfactory.getlogger(this.getclass()); @autowired private someservice someservice; @override public void execute(jobexecutioncontext context) throws jobexecutionexception { someservice.dosomething(); } }

下面代码是创建job：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 jobdetail jobdetail = jobbuilder.newjob(((job) class.forname(job.getclazz()).newinstance()).getclass()) .withidentity(job.getjobname(), job.getjobgroup()).build(); jobdetail.getjobdatamap().put("extdata", job.getextdata()); // 表达式调度构建器 cronschedulebuilder schedulebuilder = cronschedulebuilder.cronschedule(job.getcronexpression()) .withmisfirehandlinginstructiondonothing(); // 构建一个trigger triggerbuilder<crontrigger> triggerbuilder = triggerbuilder.newtrigger().withidentity(triggerkey) .withschedule(schedulebuilder); if (job.getstarttime() != null) { triggerbuilder.startat(job.getstarttime()); } if (job.getendtime() != null) { triggerbuilder.endat(job.getendtime()); } crontrigger trigger = triggerbuilder.build(); scheduler.schedulejob(jobdetail, trigger);// 注入到管理类
