spring结合Quartz的集群功能实现

2023-08-22 08:32:10

一：前沿

　　在上一篇（http://www.cnblogs.com/wuhao1991/p/4331613.html）的博客中记载了定时的功能，但是集成是没有成功的，在这篇中，我在解释下这里的”集成的含义“，这里的集成是指:比如我有两个tomcat（tomcat1,tomcat2），然后现在我先启动tomcat1,在启动tomcat2，但是定时查询的功能在tomcat1上在执行，但是tomcat2上没有执行；此时我把tomcat1停止调，tomcat2又继续执行这个定时的功能；所以这里的集成说白了就是，定时的功能只能执行一个，这两个tomcat里卖弄是互斥的关系！

二：内容技术

　　在上一篇中说过，我在配置集群的时候，老是出问题，那么现在我会把这个问题记载下来；下面进行说明吧！

application-quartz.xml配置如下

<?xml version="1.0" encoding="UTF-8" ?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:aop="http://www.springframework.org/schema/aop"

       xmlns:tx="http://www.springframework.org/schema/tx"

       xmlns:context="http://www.springframework.org/schema/context"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

    	http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd

    	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd

    	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    	<bean id="scheduTask" class="com.xpg.chargepile.quartz.ScheduTask"></bean>

    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">

    	<property name="triggers">

    		<list>

    			<bean class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">

    			 	<property name="cronExpression">

	          			<value>0/5 * * * * ?</value>

	        		</property>

	        		<property name="jobDetail">

	            		<bean class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">

	            			<property name="targetObject" ref="scheduTask"></property>

			    			<property name="targetMethod" value="doTask"></property>

<!-- 			    			是否允许任务并发执行。当值为false时，表示必须等到前一个线程处理完毕后才再启一个新的线程 -->

							<property name="concurrent" value="false"/>

	            		</bean>

	       			 </property>

    			</bean>

    		</list>

    	</property>

    	 <property name="dataSource">

        	<ref bean="dataSource"/>

        </property>

        <property name="applicationContextSchedulerContextKey" value="applicationContextKey"></property>

        <property name="configLocation" value="classpath:quartz.properties"></property>

    	 <property name="autoStartup" value="true" />

    </bean>

</beans>

　bug如下：

使得我照这个解决方案找了好久好久啊！所以看看下面的截图（http://www.objectpartners.com/2013/07/09/configuring-quartz-2-with-spring-in-clustered-mode/）

firstjob.java：

package com.gsh.graduate.quartz;

import java.util.Date;

import org.quartz.JobExecutionContext;

import org.quartz.SchedulerContext;

import org.quartz.SchedulerException;

import org.springframework.beans.factory.config.BeanDefinition;

import org.springframework.context.annotation.Scope;

import org.springframework.scheduling.quartz.QuartzJobBean;

import org.springframework.stereotype.Component;

import com.gsh.graduate.dao.UserDao;

import com.gsh.graduate.pojo.User;

@Component

@Scope(value = BeanDefinition.SCOPE_PROTOTYPE)

public class FirstJob extends QuartzJobBean {

  //  @AutoWire
　//　private UserDao userDao

      private UserDao userDao;
public void setUserDao(UserDao userDao) {

            this.userDao = userDao;

        }

        @Override

        protected void executeInternal(JobExecutionContext context) {

            //获取JobExecutionContext中的service对象

            try {

                SchedulerContext skedCtx = context.getScheduler().getContext();

                userDao=(UserDao) skedCtx.get("userDao");

            } catch (SchedulerException e) {

                e.printStackTrace();

            }

            User u=userDao.getUserByID("");

            System.out.println("---"+u);

            System.out.println("定时开始0,1,2,3");

            System.out.println(new Date());

            System.out.println("定时结束,game over");

        }

}

特别说明：这里面的对象必须在配置文件里面声明，在firstjob.java类中，如果你想通过这样像代码中注释的那样，自动注入会报一下错误；所以可以看下spring 通过配置向quartz 注入service（http://blog.csdn.net/whaosy/article/details/6298686）

上面第一次实验的那种bug本来有两种配置方式的，但是我在配置好了之后，实验以前的没有报bug，我都郁闷了，附加代码看看

这是所有的代码，两种方案

三：总结，折腾了这么久终于把集成给折腾成功了啊，这是接触新鲜的东西，就是不一样啊，解决问题的能力还是有涨进的啊！继续Go!Boy，今天一下在把有关Quartz的都写了！不枉我研究了两天啊！
