Spring整合Quartz
1、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quartz-2.2.3-distribution.tar
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”
table_mysql.sql
table_mysql_innodb.sql
上述两者所有的数据库引擎不一样
在数据库里导入table_mysql.sql内置表
2、创建工程
导入pom依赖和逆向生成插件
<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需要使用C3P0连接池将数据持久化到数据库-->
<!--Quartz各版本数据库连接池技术更新情况-->
<!--Quartz 2.0 以前 DBCP-->
<!--Quartz 2.0 以后 C3P0（包含2.0）-->
<dependency>
<groupId>com.mchange</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.5.2</version>
</dependency>
更换成Druid连接池
A、 引入依赖
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.10</version>
</dependency>
B、 导入DruidConnectionProvider.java
C、修改quartz.properties配置
#配置数据库源
org.quartz.dataSource.qzDS.connectionProvider.class:
com.xwt.项目名.util.DruidConnectionProvider

jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root

3、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
#
#============================================================================
# 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.scheduler.rmi.proxy: false
org.quartz.scheduler.wrapJobExecutionInUserTransaction: 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.tablePrefix:qrtz_
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.xwt.quartz02.util.DruidConnectionProvider
org.quartz.dataSource.qzDS.driver: com.mysql.jdbc.Driver
org.quartz.dataSource.qzDS.URL: jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=utf8
org.quartz.dataSource.qzDS.user: root
org.quartz.dataSource.qzDS.password: 123
org.quartz.dataSource.qzDS.maxConnection: 10
重写数据源的连接去更换
DruidConnectionProvider.java
package com.xwt.quartz02.util;
import com.alibaba.druid.pool.DruidDataSource;
import org.quartz.SchedulerException;
import org.quartz.utils.ConnectionProvider;
import java.sql.Connection;
import java.sql.SQLException;
public class DruidConnectionProvider implements ConnectionProvider {
/*

//JDBC驱动
public String driver;
//JDBC连接串
public String URL;
//数据库用户名
public String user;
//数据库用户密码
public String password;
//数据库最大连接数
public int maxConnection;
//数据库SQL查询每次连接返回执行到连接池，以确保它仍然是有效的。
public String validationQuery;
private boolean validateOnCheckout;
private int idleConnectionValidationSeconds;
public String maxCachedStatementsPerConnection;
private String discardIdleConnectionsSeconds;
public static final int DEFAULT_DB_MAX_CONNECTIONS = 10;
public static final int DEFAULT_DB_MAX_CACHED_STATEMENTS_PER_CONNECTION = 120;
//Druid连接池
private DruidDataSource datasource;
/*

*/
public Connection getConnection() throws SQLException {
return datasource.getConnection();
}
public void shutdown() throws SQLException {
datasource.close();
}
public void initialize() throws SQLException{
if (this.URL == null) {
throw new SQLException("DBPool could not be created: DB URL cannot be null");
}
if (this.driver == null) {
throw new SQLException("DBPool driver could not be created: DB driver class name cannot be null!");
}
if (this.maxConnection < 0) {
throw new SQLException("DBPool maxConnectins could not be created: Max connections must be greater than zero!");
}
datasource = new DruidDataSource();
try{
datasource.setDriverClassName(this.driver);
} catch (Exception e) {
try {
throw new SchedulerException("Problem setting driver class name on datasource: " + e.getMessage(), e);
} catch (SchedulerException e1) {
}
}
datasource.setUrl(this.URL);
datasource.setUsername(this.user);
datasource.setPassword(this.password);
datasource.setMaxActive(this.maxConnection);
datasource.setMinIdle(1);
datasource.setMaxWait(0);
datasource.setMaxPoolPreparedStatementPerConnectionSize(this.DEFAULT_DB_MAX_CACHED_STATEMENTS_PER_CONNECTION);
if (this.validationQuery != null) {

datasource.setTestOnReturn(true);
else

}
}
/*

*/
public String getDriver() {
return driver;
}
public void setDriver(String driver) {
this.driver = driver;
}
public String getURL() {

}
}
4、自定义MyJobFactory 解决spring不能在quartz中注入bean的问题
package com.xwt.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;
@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;
}
}
5、创建调度器schedule 交给spring进行管理
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.xwt.quartz02.quartz;
import org.quartz.Scheduler;
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;
@Configuration
public class QuartzConfiguration {
@Autowired
private MyJobFactory myJobFactory;
//创建调度器工厂
@Bean
public SchedulerFactoryBean schedulerFactoryBean(){
//1.创建SchedulerFactoryBean
//2.加载自定义的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();
}
}
配置application.yml

在Quartz02Application.java中加上注解
package com.xwt.quartz02;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@EnableTransactionManagement
@EnableScheduling

public class Quartz02Application {
public static void main(String[] args) {
SpringApplication.run(Quartz02Application.class, args);
}
}
读取数据库中表达式启动定时任务1（每5s执行）
数据库
MyJob.java
package com.xwt.quartz02.quartz;
import lombok.extern.slf4j.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());
}
}
内置表生成了数据
更改定时任务状态（启用/禁用） 定时任务1停止
内置表的数据也清空了
读取数据库中表达式启动定时任务2（每5s执行） 在对应作业类中打印定时任务2携带的参数
数据库表配置
