SpringCloud（第 054 篇）简单 Quartz-Cluster 微服务，采用注解配置 Quartz 分布式集群

一、大致介绍

1、因网友提到有没有采用注解式配置的Quartz例子，因此本人就贴上了这样一个样例；
2、至于如何修改定时任务的 cronExpression 表达式值的话，大家可以参照之前的（第 010 篇）样子看看如何修改；3、注意：配置文件中的 mysql 数据库链接配置大家就各自配置自己的哈；

二、实现步骤

2.1 添加 maven 引用包

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><artifactId>springms-simple-quartz-config-cluster</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><parent><groupId>com.springms.cloud</groupId><artifactId>springms-spring-cloud</artifactId><version>1.0-SNAPSHOT</version></parent><dependencies><!-- 访问数据库模块 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jpa</artifactId></dependency><!-- web模块 --><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 模块 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></dependency><!-- quartz 模块 --><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 线程池模块 --><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.1.3</version></dependency></dependencies></project>

2.2 添加应用配置文件（springms-simple-quartz-config-cluster\src\main\resources\application.yml）

server:port: 8405
spring:application:name: springms-simple-quartz-config-cluster  #全部小写#####################################################################################################
# mysql 属性配置datasource:driver-class-name: com.mysql.jdbc.Driverurl: jdbc:mysql://ip:3306/hmilyylimh?useUnicode=true&characterEncoding=UTF-8&autoReconnect=trueusername: usernamepassword: passwordjpa:hibernate:#ddl-auto: create #ddl-auto:设为create表示每次都重新建表ddl-auto: update #ddl-auto:设为update表示每次都不会重新建表show-sql: true

# 打印日志
logging:level:root: INFOorg.hibernate: INFOorg.hibernate.type.descriptor.sql.BasicBinder: TRACEorg.hibernate.type.descriptor.sql.BasicExtractor: TRACEcom.springms: DEBUG
#####################################################################################################

2.3 添加 quartz 配置文件（springms-simple-quartz-config-cluster/src/main/resources/quartz.properties）

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

2.4 添加数据源配置类（springms-simple-quartz-config-cluster\src\main\java\com\springms\cloud\config\DataSourceConfig.java）

package com.springms.cloud.config;import org.apache.tomcat.jdbc.pool.DataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;import javax.annotation.Resource;/*** 数据源配置。** @author hmilyylimh** @version 0.0.1** @date 2017/12/17**/
@Configuration
public class DataSourceConfig {@Resourceprivate Environment env;@Beanpublic DataSource dataSource(){DataSource configDataSource = new DataSource();configDataSource.setUrl("jdbc:mysql://ip:3306/hmilyylimh?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true");configDataSource.setDriverClassName("com.mysql.jdbc.Driver");configDataSource.setUsername("username");configDataSource.setPassword("password");configDataSource.setInitialSize(5);configDataSource.setDefaultAutoCommit(true);if(configDataSource.getUrl().startsWith("jdbc:mysql://ip")){throw new RuntimeException("请配置数据源地址");}if(configDataSource.getUsername().startsWith("username")){throw new RuntimeException("请配置数据源用户名");}if(configDataSource.getPassword().startsWith("password")){throw new RuntimeException("请配置数据源密码");}// 这些配置看个人需要，需要的话可以全部配置起来，我这里写Demo的话就没有全部配置起来了//configDataSource.setInitialSize();//configDataSource.setMinEvictableIdleTimeMillis();//configDataSource.setNumTestsPerEvictionRun();//configDataSource.setTestWhileIdle();//configDataSource.setMaxActive();//configDataSource.setMaxIdle();//configDataSource.setMinIdle();//configDataSource.setMaxWait();//configDataSource.setRemoveAbandoned();//configDataSource.setRemoveAbandonedTimeout();//configDataSource.setValidationQuery();//configDataSource.setValidationQueryTimeout();//configDataSource.setValidationInterval();//configDataSource.setTimeBetweenEvictionRunsMillis();return configDataSource;}
}

2.5 添加Quartz调度配置类（springms-simple-quartz-config-cluster\src\main\java\com\springms\cloud\config\QuartzSchedulerConfig.java）

}

2.6 添加定时调度任务Job1（springms-simple-quartz-config-cluster\src\main\java\com\springms\cloud\job\Job1.java）

package com.springms.cloud.job;import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
import org.springframework.stereotype.Component;import java.text.SimpleDateFormat;

@Component
public class Job1 extends QuartzJobBean {@Overrideprotected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {System.out.println("@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@");System.out.println("@@@@@@@@@@@@        "+(new SimpleDateFormat("yyyy-mm-dd HH:mm:ss.SSSSSS")).format(new Date())+"         @@@@@@@@@@@");System.out.println("@@@@@@@@@@@@@@@@@@@@@@@        Job1         @@@@@@@@@@@@@@@@@@@@@@");System.out.println("@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@");System.out.println();}
}

2.7 添加定时调度任务Job2（springms-simple-quartz-config-cluster\src\main\java\com\springms\cloud\job\Job2.java）

}

2.8 执行 Quartz 的 11 张表入数据库（springms-simple-quartz-config-cluster/quartz-tables.log）

2.9 添加 Quartz-Cluster 启动类（springms-simple-quartz-config-cluster\src\main\java\com\springms\cloud\SimpleQuartzConfigClusterApplication.java）

package com.springms.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;/*** 简单 Quartz-Cluster 微服务，采用注解配置 Quartz 分布式集群。** @author hmilyylimh** @version 0.0.1** @date 2017/12/17**/
@SpringBootApplication
public class SimpleQuartzConfigClusterApplication {private static final Logger Logger = LoggerFactory.getLogger(SimpleQuartzConfigClusterApplication.class);public static void main(String[] args) {SpringApplication.run(SimpleQuartzConfigClusterApplication.class, args);System.out.println("【【【【【【 简单Quartz-Config-Cluster微服务 】】】】】】已启动.");}
}

三、测试

/****************************************************************************************一、简单 Quartz-Cluster 微服务，采用注解配置 Quartz 分布式集群：1、添加 Quartz 相关配置文件；2、启动 springms-simple-quartz-config-cluster 模块服务，启动3个端口（8405、8406、8407）；3、然后看到 3 台服务器只有 1 台服务器调用了 Job1 类中的方法，因此 Quartz 的集群分布式也算是部署成功了；4、然后关闭 1 台活跃 Quartz 服务器；5、再等一会儿就看到 2 台服务器中的 1 台服务器每隔一定的时间调用 Job1 类中的方法；****************************************************************************************/
