Spring4+Quartz2计划任务集群

 项目中经常需要计划任务来定时处理一些事情，Quartz是javaEE项目最常见的计划任务组件，Quartz本身支持集群，和spring结合很容易实现计划任务的配置，但是默认spring的Quartz配置

org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean

并不支持集群模，当项目集群化部署的时候，项目中的计划任务有些事不能重复执行的，所以需要把job调度器换为

org.springframework.scheduling.quartz.JobDetailFactoryBean

并重写其中的jobClass。

重写的类：KuanrfQuartzJob.java

package com.kuanrf.common.util;

import java.lang.reflect.Method;

import org.quartz.DisallowConcurrentExecution;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

/**

* @version [版本号, 2015年12月14日]
* @see [相关类/方法]

*/
@DisallowConcurrentExecution
public class KuanrfQuartzJob extends QuartzJobBean {

// 计划任务所在类
private String targetObject;

// 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;
}

}

spring配置：application_spring_trigger.xml

targetObject：定义计划任务的类

targetMethod：具体计划任务（方法名）
