SpringCloud 整合 Quartz 支持集群，支持動態修改 Quartz 執行時間
一、添加 maven 引用包
<dependencies>
<!-- 訪問數據庫模塊 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<!-- web模塊 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- MYSQL -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<!-- Jdbc 模塊 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<!-- log4j 日志模塊 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j</artifactId>
</dependency>
<!-- quartz 模塊 -->
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz-jobs</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
</dependency>
<!-- druid 線程池模塊 -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.3</version>
</dependency>
二、添加 3 個配置文件
1、src\main\resources\application.yml 文件：
server:
port: 8395
spring:
application:
name: microservice-simple-quartz-cluster
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://ip:port/hmilyylimh?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true
username: username
password: username
jpa:
hibernate:
ddl-auto: update #ddl-auto:設為update表示每次都不會重新建表
show-sql: true
2、src\main\resources\quartz.properties 文件，配置quartz：
org.quartz.scheduler.instanceName = quartzScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.isClustered = true
org.quartz.jobStore.useProperties = false
org.quartz.jobStore.clusterCheckinInterval = 20000
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
3、src\main\resources\quartz.xml 文件，配置定時任務：
<?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:p="http://www.springframework.org/schema/p"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd

<property name="applicationContextSchedulerContextKey" value="applicationContext" />
<property name="configLocation" value="classpath:quartz.properties" />
</bean>
</beans>
三、DetailQuartzJobBean 加載類和方法
package com.itmuch.cloud.job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.LoggerFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;
import java.lang.reflect.Method;
import java.text.SimpleDateFormat;
import java.util.Date;
public class DetailQuartzJobBean extends QuartzJobBean {
private String targetObject;
private String targetMethod;
private ApplicationContext ctx;
// 配置中設定了
// ① targetMethod: 指定需要定時執行scheduleInfoAction中的simpleJobTest()方法
// ② concurrent：對于相同的JobDetail，當指定多個Trigger時, 很可能第一個job完成之前，
// 第二個job就開始了。指定concurrent設為false，多個job不會并發運行，第二個job將不會在第一個job完成之前開始。
// ③ cronExpression：0/10 * * * * ?表示每10秒執行一次，具體可參考附表。
// ④ triggers：通過再添加其他的ref元素可在list中放置多個觸發器。 scheduleInfoAction中的simpleJobTest()方法
@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
try {
Object otargetObject = ctx.getBean(targetObject);
Method m = null;
System.out.println(targetObject + " - " + targetMethod + " - " + ((new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS")).format(new Date())));
try {
m = otargetObject.getClass().getMethod(targetMethod, new Class[] { JobExecutionContext.class });
m.invoke(otargetObject, new Object[] { context });
} catch (SecurityException e) {
// Logger.error(e);
System.out.println(e.getMessage());
} catch (NoSuchMethodException e) {
// Logger.error(e);
System.out.println(e.getMessage());
}
} catch (Exception e) {
System.out.println(e.getMessage());
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;
}
}

八、簡單Quartz-Cluster微服務啟動類
package com.itmuch.cloud;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
/**
* 簡單Quartz-Cluster微服務。
*
* @date 2017/9/16
*
*/
@SpringBootApplication
@ImportResource(“quartz.xml”)
public class SimpleQuartzClusterApplication {
private static final Logger Logger = LoggerFactory.getLogger(SimpleQuartzClusterApplication.class);
public static void main(String[] args) {
Logger.info("簡單Quartz-Cluster微服務入口函數編碼-" + System.getProperty("file.encoding"));
SpringApplication.run(SimpleQuartzClusterApplication.class, args);
System.out.println("【【【【【【 簡單Quartz-Cluster微服務 】】】】】】已啟動.");
}
}
九、如何測試分布式？
/******************************************************************************
一、簡單Quartz-Cluster微服務：
1、添加 Quartz 相關配置文件；
2、啟動 microservice-simple-quartz-cluster 模塊服務，啟動1個端口（8395）；
3、然后查看日志， ScheduleTask 類的 sayHello 方法被有規律的調用，并打印日志出來；
4、啟動 microservice-simple-quartz-cluster 模塊服務，再啟動2個端口（8396、8397）；
5、然后看到 3 臺服務器只有 1 臺服務器調用了 sayHello 方法，因此 Quartz 的集群分布式也算是部署成功了；
******************************************************************************/
/******************************************************************************
二、簡單Quartz-Cluster微服務（動態修改定時任務的 cronExpression 時間表達式）：
1、添加 Quartz 相關配置文件；
2、啟動 microservice-simple-quartz-cluster 模塊服務，啟動3個端口（8395、8396、8397）；
3、然后看到 3 臺服務器只有 1 臺服務器調用了 sayHello 方法打印了日志，因此 Quartz 的集群分布式也算是部署成功了；
4、然后新起網頁輸入 http://localhost:8395/modify/5 修改定時任務的觸發時間；
5、再等一會兒就看到 3 臺服務器只有 1 臺服務器每隔 5 秒調用一次 sayHello 方法，因此修改定時任務的克隆表達式也算是成功了；
******************************************************************************/
/******************************************************************************
三、簡單Quartz-Cluster微服務（動態刪除其中 1 臺活躍 Quartz 服務器，然后剩下的其中 1 臺自動接替）：
1、添加 Quartz 相關配置文件；
2、啟動 microservice-simple-quartz-cluster 模塊服務，啟動3個端口（8395、8396、8397）；
3、然后看到 3 臺服務器只有 1 臺服務器調用了 sayHello 方法打印了日志，因此 Quartz 的集群分布式也算是部署成功了；
4、然后關閉 1 臺活躍 Quartz 服務器；
5、再等一會兒就看到 2 臺服務器中的 1 臺服務器每隔一定的時間調用一次 sayHello 方法；
