sping的quartz设置定时任务

除了spring相关的jar包之外，还需要引入quartz-all-1.8.6.jar

spring配置文件增加quartz-bean.xml和quartz-set.xml

quartz-bean.xml：

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

            </map>
         </property>
    </bean>

    <!-- MethodInvokingJobDetailFactoryBean不支持序列化 -->
     <bean id="testQuartzTaskJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject"><ref bean="testQuartzTask"/></property>
        <property name="targetMethod"><value>doTask</value></property>

    <!-- 这种支持job序列化，但是这个jobClass对应的类，必须实现job，有execute方法-->

        <property name="requestsRecovery" value="true" />
    </bean> -->

</beans>

使用MethodInvokingJobDetailFactoryBean调用的类TestQuartzTask：

package com.tech.jin.quartz;

import org.apache.log4j.Logger;

public class TestQuartzTask {

    private Logger logger = Logger.getLogger(TestQuartzTask.class);

    public void doTask(){
        logger.info("66666666666666666666666");
    }
}

使用JobDetailFactoryBean调用的类TestQuartzTask：

package com.tech.jin.quartz;

import org.apache.log4j.Logger;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class TestQuartzTask implements Job{

    private Logger logger = Logger.getLogger(TestQuartzTask.class);
    @Override
    public void execute(JobExecutionContext arg0) throws JobExecutionException {
        logger.info("5555555");

    }

}

除此之外，还需要将quartz-bean.xml 和quartz-set.xml引入到ApplicationContext.xml文件中（推荐）

<import resource="spring-quartz.xml"/> 

或者在web.xml中添加上读取sping配置文件的配置：classpath:spring/quartz-*xml。

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:spring/ApplicationContext.xml;
        classpath:spring/quartz-*xml
    </param-value>
  </context-param>

如果需要集群使用，就打开quartz-set.xml中SchedulerFactoryBean注掉的datasource和配置文件。

每个server把将要及正在运行的job所有状态都即时同步到中央数据库,然后再次触发调用时从数据库中分析是否已有别的server正在运行相同job

(同名同定时时间点的job属于相当job),如果相同job正在别的server运行,那么当前server忽略本次运行的job.

Quartz的 Task（11 张表）实例化采用数据库存储，基于数据库引擎及 High-Available 的策略（集群的一种策略）自动协调每个节点的 Quartz。

spring-quartz.properties：

#==============================================================
org.quartz.scheduler.instanceName = defaultScheduler

数据库的sql版本要和squartz完全一致,在下载解压后的quartz\quartz-1.8.6\docs\dbTables文件夹在都有

tables_mysql.sql、tables_oracle.sql等...
