淄博烧烤爆红出了圈,当你坐在八大局的烧烤摊,面前是火炉、烤串、小饼和蘸料,音乐响起,啤酒倒满,烧烤灵魂的party即将开场的时候,你系统中的Scheduler(调试器),也自动根据设定的Trigger(触发器),从容优雅的启动了一系列的Job(后台定时任务)。工作一切早有安排,又何须费心劳神呢?因为boot-admin早已将Quartz这块肉串在了烤签上!
Quartz是一款Java编写的开源任务调度框架,同时它也是Spring默认的任务调度框架。它的作用其实类似于Timer定时器以及ScheduledExecutorService调度线程池,当然Quartz作为一个独立的任务调度框架表现更为出色,功能更强大,能够定义更为复杂的执行规则。
boot-admin 是一款采用前后端分离模式、基于 SpringCloud 微服务架构 + vue-element-admin 的 SaaS 后台管理框架。
那么boot-admin怎样才能将Quartz串成串呢?一共分三步:

vue页面以el-table作为任务的展示控件,串起任务的创建、修改、删除、挂起、恢复、状态查看等功能。

api定义
job.js定义访问后台接口的方式
import request from '@/utils/request' //获取空任务 export function getBlankJob() { return request({ url: '/api/system/auth/job/blank', method: 'get' }) } //获取任务列表(分页) export function fetchJobPage(data) { return request({ url: '/api/system/auth/job/page', method: 'post', data }) } //获取用于修改的任务信息 export function getUpdateObject(data) { return request({ url: '/api/system/auth/job/dataforupdate', method: 'post', data }) } //保存任务 export function saveJob(data) { return request({ url: '/api/system/auth/job/save', method: 'post', data }) } //暂停任务 export function pauseJob(data) { return request({ url: '/api/system/auth/job/pause', method: 'post', data }) } //恢复任务 export function resumeJob(data) { return request({ url: '/api/system/auth/job/resume', method: 'post', data }) } //删除任务 export function deleteJob(data) { return request({ url: '/api/system/auth/job/delete', method: 'post', data }) }
Quartz会自动创建11张数据表,数据源可以与系统主数据源相同,也可以独立设置。
笔者建议单独设置Quartz数据源。在配置文件 application.yml 添加以下内容
base2048: job: enable: true datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/base2048job?useSSL=false&serverTimezone=UTC&autoReconnect=true&allowPublicKeyRetrieval=true&useOldAliasMetadataBehavior=true username: root password: mysql
数据源配置类如下:
@Configuration public class QuartzDataSourceConfig { @Primary @Bean(name = "defaultDataSource") @ConfigurationProperties(prefix = "spring.datasource") public DruidDataSource druidDataSource() { return new DruidDataSource(); } @Bean(name = "quartzDataSource") @QuartzDataSource @ConfigurationProperties(prefix = "base2048.job.datasource") public DruidDataSource quartzDataSource() { return new DruidDataSource(); } }
在 resources 下添加 quartz.properties 文件,内容如下:
# 固定前缀org.quartz # 主要分为scheduler、threadPool、jobStore、plugin等部分 # # org.quartz.scheduler.instanceName = DefaultQuartzScheduler org.quartz.scheduler.rmi.export = false org.quartz.scheduler.rmi.proxy = false org.quartz.scheduler.wrapJobExecutionInUserTransaction = false <!-- 每个集群节点要有独立的instanceId --> org.quartz.scheduler.instanceId = 'AUTO' # 实例化ThreadPool时,使用的线程类为SimpleThreadPool org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool # threadCount和threadPriority将以setter的形式注入ThreadPool实例 # 并发个数 org.quartz.threadPool.threadCount = 15 # 优先级 org.quartz.threadPool.threadPriority = 5 org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true org.quartz.jobStore.misfireThreshold = 5000 # 默认存储在内存中 #org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore #持久化 org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX org.quartz.jobStore.tablePrefix = QRTZ_ org.quartz.jobStore.dataSource = qzDS org.quartz.dataSource.qzDS.maxConnections = 10
调度器配置类内容如下:
@Configuration public class SchedulerConfig { @Autowired private MyJobFactory myJobFactory; @Value("${base2048.job.enable:false}") private Boolean JOB_LOCAL_RUNING; @Value("${base2048.job.datasource.driver-class-name}") private String dsDriver; @Value("${base2048.job.datasource.url}") private String dsUrl; @Value("${base2048.job.datasource.username}") private String dsUser; @Value("${base2048.job.datasource.password}") private String dsPassword; @Bean public SchedulerFactoryBean schedulerFactoryBean() throws IOException { SchedulerFactoryBean factory = new SchedulerFactoryBean(); factory.setOverwriteExistingJobs(true); // 延时启动 factory.setStartupDelay(20); // 用于quartz集群,QuartzScheduler 启动时更新己存在的Job // factory.setOverwriteExistingJobs(true); // 加载quartz数据源配置 factory.setQuartzProperties(quartzProperties()); // 自定义Job Factory,用于Spring注入 factory.setJobFactory(myJobFactory); // 在com.neusoft.jn.gpbase.quartz.job.BaseJobTemplate 同样出现该配置 //原因 : qrtz 在集群模式下 存在 同一个任务 一个在A服务器任务被分配出去 另一个B服务器任务不再分配的情况. // if(!JOB_LOCAL_RUNING){ // 设置调度器自动运行 factory.setAutoStartup(false); } return factory; } @Bean public Properties quartzProperties() throws IOException { PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean(); propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties")); propertiesFactoryBean.afterPropertiesSet(); Properties properties = propertiesFactoryBean.getObject(); properties.setProperty("org.quartz.dataSource.qzDS.driver",dsDriver); properties.setProperty("org.quartz.dataSource.qzDS.URL",dsUrl); properties.setProperty("org.quartz.dataSource.qzDS.user",dsUser); properties.setProperty("org.quartz.dataSource.qzDS.password",dsPassword); return properties; } /* * 通过SchedulerFactoryBean获取Scheduler的实例 */ @Bean(name="scheduler") public Scheduler scheduler() throws Exception { return schedulerFactoryBean().getScheduler(); } }
