修改连接池为druid
一般quartz的默认连接池是才c3p0，如果用默认连接池就不需要修改了，但是我这里要使用druid连接池
Druid连接池Quartz的工具类

在项目开发中是需要在Job中操作数据库的，那么当然需要把它交给spring管理，
但是quartz本身是不支持的，所以我们需要修改它的底层代码，让我们的Job类能被spring所管理
MyJobFactory
package com.qz.quartz02.utils; 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 { //这个对象Spring会帮我们自动注入进来 @Autowired private AutowireCapableBeanFactory autowireCapableBeanFactory; //重写创建Job任务的实例方法 @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 super.createJobInstance(bundle); } }
quartz.properties
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
# #============================================================================ # 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.qz.quartz02.utils.DruidConnectionProvider org.quartz.dataSource.qzDS.driver: com.mysql.jdbc.Driver org.quartz.dataSource.qzDS.URL: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8 org.quartz.dataSource.qzDS.user: root org.quartz.dataSource.qzDS.password: root org.quartz.dataSource.qzDS.maxConnection: 10
QuartzConfiguration把刚刚配置的东西都加到这个类里面来
package com.qz.quartz02.config; import com.qz.quartz02.utils.MyJobFactory; 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(); } }
添加配置文件generatorConfig.xml
让mybatis逆向生成代码

jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8 jdbc.username=root jdbc.password=root jdbc.initialSize=10 jdbc.maxTotal=100 jdbc.maxIdle=50 jdbc.minIdle=10 jdbc.maxWaitMillis=-1
然后在对应的mapper加入方法去实现
ScheduleTriggerMapper
/** * 查询出当前任务类对应所需的参数 * @param triggerId * @return */ /** * 查询触发器中包含的所有任务 * @return */ List<ScheduleTrigger> queryScheduleTriggerLst();
ScheduleTriggerParamMapper
/** * 查询触发器中包含的所有任务 * @return */ List<ScheduleTrigger> queryScheduleTriggerLst(); /** * 查询出当前任务类对应所需的参数 * @param triggerId * @return */ List<ScheduleTriggerParam> queryScheduleParamLst(Integer triggerId);
