spring boot + quartz 集群

InvokingJobDetailDetailFactory对象：

// 计划任务所在类

// 具体需要执行的计划任务
private String targetMethod;
private ApplicationContext ctx;
@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
try {
Object otargetObject = ctx.getBean(targetObject);
Method m = null;
try {
m = otargetObject.getClass().getMethod(targetMethod);
m.invoke(otargetObject);
} catch (SecurityException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
} catch (Exception e) {
throw new JobExecutionException(e);
}
}
public void setApplicationContext(ApplicationContext applicationContext) {
this.ctx = applicationContext;
}
public void setTargetObject(String targetObject) {
this.targetObject = targetObject;
}
public void setTargetMethod(String targetMethod) {
this.targetMethod = targetMethod;
}
}
备注：set方法不能少，setApplicationContext中的applicationContext与factory.setApplicationContextSchedulerContextKey("applicationContext")填入的值有关，其原理由InvokingJobDetailDetailFactory父类中的BeanWrapper实现。

quartz集群实现原理，利用数据库记录job行为，并通过锁机制，使job在同一次中仅运行一次。
JobBean示例
//需要交由spring管理
@Service("dialogJob")
public class DialogJob { @Autowired
private QuestionService questionService;
// 方法名在quartz定义
public void execute() throws Exception{
//具体执行业务
questionService.XXXXX();
} }
