1、Spring整合Quartz

quartz调度框架是有内置表的：

进入quartz的官网http://www.quartz-scheduler.org/，点击Downloads，
下载后在目录\docs\dbTables下有常用数据库创建quartz表的脚本，例如：“tables_mysql.sql”
tables_mysql.sql 、tables_mysql_innodb.sql 上述两者所有的数据库引擎不一样

导入之后，数据会出现下列几张表，但没有数据

导入pom依赖：

   <dependency>
	<groupId>org.quartz-scheduler</groupId>
	<artifactId>quartz-jobs</artifactId>
	<version>2.2.1</version>
   </dependency>
   <dependency>
   	<groupId>org.springframework.boot</groupId>
   	<artifactId>spring-boot-starter-quartz</artifactId>
   </dependency>
   

quartz 采用的连接池是C3P0 技术，这里替换成druid
导入druid的依赖

   <dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>druid-spring-boot-starter</artifactId>
	<version>1.1.10</version>
   </dependency>

在项目中添加quartz.properties文件(这样就不会加载自带的properties文件)
此文件的内容主要分为：scheduler，ThreadPool，JobStore，plugin，Datasources等部分，
覆盖properties文件的目的是覆盖默认的数据源，更换为druid的数据配置


quartz.properties（更改默认数据源）

#
#============================================================================
# Configure Main Scheduler Properties 调度器属性
#============================================================================
org.quartz.scheduler.instanceName: DefaultQuartzScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.rmi.export: false

org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount= 10
org.quartz.threadPool.threadPriority: 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread: true
org.quartz.jobStore.misfireThreshold: 60000
#============================================================================
# Configure JobStore

#存储方式使用JobStoreTX，也就是数据库
org.quartz.jobStore.class: org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass:org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#使用自己的配置文件
org.quartz.jobStore.useProperties:true
#数据库中quartz表的表名前缀

org.quartz.jobStore.dataSource:qzDS
#是否使用集群（如果项目只部署到 一台服务器，就不用了）
org.quartz.jobStore.isClustered = true
#============================================================================
# Configure Datasources
#============================================================================
#配置数据库源（org.quartz.dataSource.qzDS.maxConnections: c3p0配置的是有s的，druid数据源没有s）
org.quartz.dataSource.qzDS.connectionProvider.class:com.cbw.quartz02.util.DruidConnectionProvider
org.quartz.dataSource.qzDS.driver: com.mysql.jdbc.Driver
org.quartz.dataSource.qzDS.URL: jdbc:mysql://localhost:3306/book?useUnicode=true&characterEncoding=utf8
org.quartz.dataSource.qzDS.user: root
org.quartz.dataSource.qzDS.password: 123
org.quartz.dataSource.qzDS.maxConnection: 10

注意更改数据连接：

（解决自定义作业类被spring管理的问题）
MyJobFactory.java

@Slf4j是用作日志输出的，一般会在项目每个类的开头加入该注解，如果不写下面这段代码，并且想用log
private final Logger logger = LoggerFactory.getLogger(当前类名.class);

package com.cbw.quartz02.quartz;

import lombok.extern.slf4j.Slf4j;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.AdaptableJobFactory;
import org.springframework.stereotype.Component;

/**
 * @author cbw
 * @site www.cbw.com
 * @company xxx公司
 * @create 2020-01-04 21:29
 */
@Component
@Slf4j
public class MyJobFactory extends AdaptableJobFactory {
    
    // 这个由spring自动注入
    @Autowired
    private AutowireCapableBeanFactory autowireCapableBeanFactory;

    // 重写job任务对象的创建实例方法
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
    
        Object jobInstance = super.createJobInstance(bundle);
        // 通过以下方式，解决job任务无法使用spring中的Bean问题
        autowireCapableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}

创建调度器schedule
（QuartzConfiguration.java） quartz调度框架与spring框架整合的配置类，主要是要将org.quartz.Scheduler交给spring进行管理

package com.cbw.quartz02.quartz;

import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.PropertiesFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import java.io.IOException;
import java.util.Properties;

/**
 * @author cbw
 * @site www.cbw.com
 * @company xxx公司
 * @create 2020-01-04 21:43
 */
@Configuration
public class QuartzConfiguration {
    
    @Autowired
    private MyJobFactory myJobFactory;

    // 创建调度工厂
    @Bean
    public SchedulerFactoryBean schedulerFactoryBean() {
    
        // 1.创建schedulerFactoryBean
        // 2.加载自定义quartz.properties 配置文件
        // 3.设置MyJobFactory
        SchedulerFactoryBean factoryBean = new SchedulerFactoryBean();
        try {
    
            factoryBean.setQuartzProperties(quartzProperties());
            factoryBean.setJobFactory(myJobFactory);
            return factoryBean;
        } catch (IOException e) {
    
            throw new RuntimeException(e);
        }
    }

    @Bean
    public Properties quartzProperties() throws IOException {
    
        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
        propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
        propertiesFactoryBean.afterPropertiesSet();
        return propertiesFactoryBean.getObject();
    }

    @Bean(name = "scheduler")
    public Scheduler scheduler(){
    
        return schedulerFactoryBean().getScheduler();
    }
}

加入yml配置

server:
  servlet:
    context-path: /quartz
spring:
  datasource:
    #1.JDBC
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/book?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
    username: root
    password: 123
    druid:
      #2.连接池配置
      #初始化连接池的连接数量 大小，最小，最大
      initial-size: 5
      min-idle: 5
      max-active: 20
      #配置获取连接等待超时的时间
      max-wait: 60000
      #配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
      time-between-eviction-runs-millis: 60000
      # 配置一个连接在池中最小生存的时间，单位是毫秒
      min-evictable-idle-time-millis: 30000
      validation-query: SELECT 1 FROM DUAL
      test-while-idle: true
      test-on-borrow: true
      test-on-return: false
      # 是否缓存preparedStatement，也就是PSCache  官方建议MySQL下建议关闭   个人建议如果想用SQL防火墙 建议打开
      pool-prepared-statements: true
      max-pool-prepared-statement-per-connection-size: 20
      # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
      filter:
        stat:
          merge-sql: true
          slow-sql-millis: 5000
      #3.基础监控配置
      web-stat-filter:
        enabled: true
        url-pattern: /*
        #设置不统计哪些URL
        exclusions: "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*"
        session-stat-enable: true
        session-stat-max-count: 100
      stat-view-servlet:
        enabled: true
        url-pattern: /druid/*
        reset-enable: true
        #设置监控页面的登录名和密码
        login-username: admin
        login-password: admin
        allow: 127.0.0.1
       

#显示日志
logging:
  level:
    com.cbw.quartz02.mapper: debug

目前quartz可以说是整合完毕了；

2、案例使用

自定义的业务表

– 自定义的业务表
SELECT * FROM t_schedule_trigger;
SELECT * FROM t_schedule_trigger_param;
– quartz调度框架自带的表
SELECT * FROM qrtz_scheduler_state;
SELECT * FROM qrtz_cron_triggers;
SELECT * FROM qrtz_simple_triggers
SELECT * FROM qrtz_triggers;
SELECT * FROM qrtz_job_details;

案例一：读取数据库中表达式启动定时任务
数据库表t_schedule_trigger配置

MyJob.java
工作类

package com.cbw.quartz02.quartz;

import lombok.extern.slf4j.Slf4j;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
@Slf4j
public class MyJob implements Job {
    
    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
    
        System.out.println("MyJob是一个空的任务计划,时间："+new Date().toLocaleString());
    }
}

案例2：更改数据库调度器表t_schedule_trigger的state状态


当禁用触发器，只会执行spring的定时任务。

案例3：定时任务中携带参数
工作类：job1

package com.cbw.quartz02.quartz;

import com.cbw.quartz02.server.ScheduleTriggerParamService;
import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
@Slf4j
public class MyJob1 implements Job {
    

    @Autowired
    private ScheduleTriggerParamService scheduleTriggerParamService;

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
    
        JobDetail jobDetail = jobExecutionContext.getJobDetail();
        JobDataMap jobDataMap = jobDetail.getJobDataMap();
        System.out.println(new Date().toLocaleString()+"-->携带参数个数:"+jobDataMap.size());
    }
}

案例4：更改定时任务规则
一开始的规则是10秒执行一次

MyJob2

package com.cbw.quartz02.quartz;

import com.cbw.quartz02.server.ScheduleTriggerParamService;
import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
@Slf4j
public class MyJob1 implements Job {
    

    @Autowired
    private ScheduleTriggerParamService scheduleTriggerParamService;

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
    
        JobDetail jobDetail = jobExecutionContext.getJobDetail();
        JobDataMap jobDataMap = jobDetail.getJobDataMap();
        System.out.println(new Date().toLocaleString()+"-->携带参数个数:"+jobDataMap.size());
    }
}

3、页面版任务CRUD

正在努力中。。。。。
