信步漫談之Quartz—分佈式調度（整合spring早期版本【低於spring3.1】）

時間 2019-12-09

標籤信步漫談 quartz 分佈式調度整合 spring 早期版本低於spring3.1 欄目 Quartz 简体版

原文原文鏈接

1、環境

使用的jar包：spring2.5.六、quartz1.8.6 html

2、注意點

由於spring內置的quartz版本變化，因此存在spring和quartz版本接口兼容狀況，以下： java

1）spring3.1以後的版本（包含）兼容quartz2.X（這裏有個坑，網絡資料是spring3.0對應quartz1.X，但也有人說支持quartz2.X，只要不在spring的配置文件中使用，直接在程序中調用就能夠（廢話），具體須要驗證） mysql

2）spring3.1以前的版本兼容quartz1.X web

3、實現方案

Demo程序目錄結構： spring

Demo核心程序源碼：sql

package com.alfred.java.quartz.distschedule.springdemo01;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.quartz.JobExecutionException;

public class JobHello {

	private static String NUM = "1";

	private static Integer count = 1;

	private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

	protected void executeInternal()
			throws JobExecutionException {
		System.out.println("job hello"+NUM+":"+(count++)+":"+sdf.format(new Date()));
	}

	public static void setNUM(String nUM) {
		NUM = nUM;
	}

}

pom.xml

使用spring2.5.6+quartz1.8.6狀況下，按正常的spring配置方式調用，會提示一個序列化錯誤（java.io.NotSerializableException）數據庫

解決方式就是引入BeanInvokingJobDetailFactoryBean.java和MethodInvokingJobDetailFactoryBean.java（官方下載地址：https://jira.springsource.org/browse/SPR-3797），調用方式見上方applicationContext.xml。apache

package frameworkx.springframework.scheduling.quartz;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.quartz.Job;
import org.quartz.JobDetail;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.Scheduler;
import org.quartz.StatefulJob;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.BeanNameAware;

/**
 * This is a cluster safe Quartz/Spring FactoryBean implementation, which produces a JobDetail implementation that can invoke any no-arg method on any bean deployed within a Spring container.
 * <p>
 * Use this Class instead of the MethodInvokingJobDetailBeanFactory Class provided by Spring when deploying to a web environment like Tomcat.
 * <p>
 * <b>Implementation</b><br>
 * The Spring ApplicationContext cannot be passed to a Job via the JobDataMap, because it is not Serializable (and for very good reason!)
 * So, instead of associating an ApplicationContext with a JobDetail or a Trigger object, I made the [Stateful]BeanInvokingJob, which is not persisted in the database, get the applicationContext from the BeanInvokingJobDetailFactoryBean, which is ApplicationContextAware, when the [Stateful]BeanInvokingJob is created and executed.
 * <p>
 * The name or id of the of the bean to invoke (targetBean) and the method to invoke (targetMethod) must be provided in the bean declaration or a JobExecutionException will be thrown.
 * <p>
 * I wrote BeanInvokingJobDetailFactoryBean, because the MethodInvokingJobDetailFactoryBean does not produce Serializable
 * JobDetail objects, and as a result cannot be deployed into a clustered environment (as is documented within the Class).
 * <p>
 * <b>Example</b>
 * <code>
 * <ul>
 * 	&lt;bean id="<i>exampleBean</i>" class="example.ExampleImpl"&gt;
	&lt;/bean&gt;
	<p>
 * 	&lt;bean id="<i>exampleTrigger</i>" class="org.springframework.scheduling.quartz.CronTriggerBean"&gt;
 * <ul>
	<i>&lt;!-- Execute exampleBean.fooBar() at 2am every day --&gt;</i><br>
	&lt;property name="cronExpression" value="0 0 2 * * ?" /&gt;<br>
	&lt;property name="jobDetail"&gt;
	<ul>
	&lt;bean class="frameworkx.springframework.scheduling.quartz.<b>BeanInvokingJobDetailFactoryBean</b>"&gt;
	<ul>
	&lt;property name="concurrent" value="<i>false</i>"/&gt;<br>
	&lt;property name="targetBean" value="<i>exampleBean</i>" /&gt;<br>
	&lt;property name="targetMethod" value="<i>fooBar</i>" /&gt;<br>
	&lt;property name="arguments"&gt;
	<ul>
		&lt;list&gt;
		<ul>
			&lt;value&gt;arg1Value&lt;/value&gt;<br>
			&lt;value&gt;arg2Value&lt;/value&gt;
		</ul>
		&lt;list&gt;
	</ul>
	&lt;/property&gt;
	</ul>
	&lt;/bean&gt;
	</ul>
	&lt;/property&gt;
	</ul>
	&lt;/bean&gt;
	<p>
	&lt;bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"&gt;
	<ul>
	&lt;property name="triggers"&gt;
	<ul>
	&lt;list&gt;
	<ul>
	&lt;ref bean="<i>exampleTrigger</i>" /&gt;
	</ul>
	&lt;/list&gt;
	</ul>
	&lt;/property&gt;
	</ul>
	&lt;/bean&gt;
	</ul>
 * </code>
 * In this example we created a BeanInvokingJobDetailFactoryBean, which will produce a JobDetail Object with the jobClass property set to StatefulBeanInvokingJob.class (concurrent=="false"; Set to BeanInvokingJob.class when concurrent=="true"), which will in turn invoke the <code>fooBar</code>(String, String) method of the bean with id "<code>exampleBean</code>".  Method <code>arguments</code> are optional.  In this case there are two String arguments being provided to the <code>fooBar</code> method.  The Scheduler is the heart of the whole operation; without it, nothing will happen.

 * <p>
 * <b>Troubleshooting</b>
 * <p>
 * <b>Error:</b> java.io.IOException: JobDataMap values must be Strings when the 'useProperties' property is set.  Key of offending value: arguments<br>
 * <b>Solution:</b> do not set the <code>arguments</code> property when <code>org.quartz.jobstore.useProperty</code> is set to "true" in <code>quartz.properties</code>.

/**
 * This is a cluster safe Quartz/Spring FactoryBean implementation, which produces a JobDetail implementation that can invoke any no-arg method on any Class.
 * <p>
 * Use this Class instead of the MethodInvokingJobDetailBeanFactory Class provided by Spring when deploying to a web environment like Tomcat.
 * <p>
 * <b>Implementation</b><br>
 * Instead of associating a MethodInvoker with a JobDetail or a Trigger object, like Spring's MethodInvokingJobDetailFactoryBean does, I made the [Stateful]MethodInvokingJob, which is not persisted in the database, create the MethodInvoker when the [Stateful]MethodInvokingJob is created and executed.
 * <p>
 * A method can be invoked one of several ways:
 * <ul>
 * <li>The name of the Class to invoke (targetClass) and the static method to invoke (targetMethod) can be specified.
 * <li>The Object to invoke (targetObject) and the static or instance method to invoke (targetMethod) can be specified (the targetObject must be Serializable when concurrent=="false").
 * <li>The Class and static Method to invoke can be specified in one property (staticMethod). example: staticMethod = "example.ExampleClass.someStaticMethod"
 * <br><b>Note:</b>  An Object[] of method arguments can be specified (arguments), but the Objects must be Serializable if concurrent=="false".
 * </ul>  
 * <p>
 * I wrote MethodInvokingJobDetailFactoryBean, because Spring's MethodInvokingJobDetailFactoryBean does not produce Serializable
 * JobDetail objects, and as a result cannot be deployed into a clustered environment like Tomcat (as is documented within the Class).
 * <p>
 * <b>Example</b>
 * <code>
 * <ul>
 * 	&lt;bean id="<i>exampleTrigger</i>" class="org.springframework.scheduling.quartz.CronTriggerBean"&gt;
 * <ul>
	<i>&lt;!-- Execute example.ExampleImpl.fooBar() at 2am every day --&gt;</i><br>
	&lt;property name="<a href="http://www.opensymphony.com/quartz/api/org/quartz/CronTrigger.html">cronExpression</a>" value="0 0 2 * * ?" /&gt;<br>
	&lt;property name="jobDetail"&gt;
	<ul>
	&lt;bean class="frameworkx.springframework.scheduling.quartz.<b>MethodInvokingJobDetailFactoryBean</b>"&gt;
	<ul>
	&lt;property name="concurrent" value="<i>false</i>"/&gt;<br>
	&lt;property name="targetClass" value="<i>example.ExampleImpl</i>" /&gt;<br>
	&lt;property name="targetMethod" value="<i>fooBar</i>" /&gt;
	</ul>
	&lt;/bean&gt;
	</ul>
	&lt;/property&gt;
	</ul>
	&lt;/bean&gt;
	<p>
	&lt;bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"&gt;
	<ul>
	&lt;property name="triggers"&gt;
	<ul>
	&lt;list&gt;
	<ul>
	&lt;ref bean="<i>exampleTrigger</i>" /&gt;
	</ul>
	&lt;/list&gt;
	</ul>
	&lt;/property&gt;
	</ul>
	&lt;/bean&gt;
	</ul>
 * </code>
 * In this example we created a MethodInvokingJobDetailFactoryBean, which will produce a JobDetail Object with the jobClass property set to StatefulMethodInvokingJob.class (concurrent=="false"; Set to MethodInvokingJob.class when concurrent=="true"), which will in turn invoke the static <code>fooBar</code>() method of the "<code>example.ExampleImpl</code>" Class. The Scheduler is the heart of the whole operation; without it, nothing will happen.

		 * The Class is identified by the "targetClass" entry in the JobDataMap of the JobExecutionContext provided.  If targetClass is specified, then targetMethod must be a static method.<br>
		 * The Object is identified by the 'targetObject" entry in the JobDataMap of the JobExecutionContext provided.  If targetObject is provided, then targetClass will be overwritten.  This Object must be Serializable when <code>concurrent</code> is set to false.<br>
		 * The method is identified by the "targetMethod" entry in the JobDataMap of the JobExecutionContext provided.<br>
		 * The "staticMethod" entry in the JobDataMap of the JobExecutionContext can be used to specify a Class and Method in one entry (ie: "example.ExampleClass.someStaticMethod")<br>
		 * The method arguments (an array of Objects) are identified by the "arguments" entry in the JobDataMap of the JobExecutionContext.  All arguments must be Serializable when <code>concurrent</code> is set to false.
		 * <p>
		 * Logging is provided at the DEBUG and INFO levels; 8 lines at the DEBUG level, and 1 line at the INFO level.
