摘要：加载配置文件失败加载配置文件失败添加定时调度任务定时调度任务添加定时调度任务定时调度任务执行的张表入数据库添加启动类简单微服务，采用注解配置分布式集群。

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



    4.0.0

    springms-simple-quartz-config-cluster
    1.0-SNAPSHOT
    jar
    
    
        com.springms.cloud
        springms-spring-cloud
        1.0-SNAPSHOT
    
    
    
        
        
            org.springframework.boot
            spring-boot-starter-data-jpa
        

        
        
            org.springframework.boot
            spring-boot-starter-web
        

        
        
            mysql
            mysql-connector-java
        

        
        
            org.springframework.boot
            spring-boot-starter-jdbc
        
               
        
        
            org.quartz-scheduler
            quartz
            2.3.0
        
        
            org.quartz-scheduler
            quartz-jobs
            2.3.0
        
        
            org.springframework
            spring-context-support
        

        
        
            com.alibaba
            druid
            1.1.3

2.2 添加应用配置文件（springms-simple-quartz-config-clustersrcmainresourcesapplication.yml）

server:
  port: 8405
spring:
  application:
    name: springms-simple-quartz-config-cluster  #全部小写

    username: username
    password: password
  jpa:

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-clustersrcmainjavacomspringmscloudconfigDataSourceConfig.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 {

    @Resource
    private Environment env;

    @Bean
    public 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-clustersrcmainjavacomspringmscloudconfigQuartzSchedulerConfig.java）

package com.springms.cloud.config;

import com.springms.cloud.job.Job1;
import com.springms.cloud.job.Job2;

2.9 添加 Quartz-Cluster 启动类（springms-simple-quartz-config-clustersrcmainjavacomspringmscloudSimpleQuartzConfigClusterApplication.java）

package com.springms.cloud;

@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；
