Question

尝试将我的项目从Spring Boot 1.5.8更新到2.0.1并且遇到Quartz问题。我使用Spring BOM并使用Quartz 2.3.0版本。

这是我为Quart设置bean的QuartzConfigurer：

import lombok.extern.slf4j.Slf4j;
import org.quartz.JobDetail;
import org.quartz.Trigger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.quartz.CronTriggerFactoryBean;
import org.springframework.scheduling.quartz.JobDetailFactoryBean;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

import javax.annotation.PostConstruct;

@Slf4j
@Configuration
public class QuartzConfigurer {

    @Value("${quartz.cron.contract-status}")
    private String contractCron;

    @Value("${quartz.config-filename}")
    private String quartzConfigFileName;

    @Autowired
    private ApplicationContext applicationContext;

    @PostConstruct
    public void init() {
        log.debug("Initialization of quartz configurer");
    }

    @Bean
    public SpringBeanJobFactory springBeanJobFactory() {
        AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
        jobFactory.setApplicationContext(applicationContext);
        return jobFactory;
    }

    @Bean
    public SchedulerFactoryBean scheduler(Trigger trigger, JobDetail job) {
        SchedulerFactoryBean schedulerFactory = new SchedulerFactoryBean();
        schedulerFactory.setConfigLocation(new ClassPathResource(quartzConfigFileName));

        schedulerFactory.setJobFactory(springBeanJobFactory());
        schedulerFactory.setJobDetails(job);
        schedulerFactory.setTriggers(trigger);
        return schedulerFactory;
    }

    @Bean
    public JobDetailFactoryBean jobDetail() {
        JobDetailFactoryBean jobDetailFactory = new JobDetailFactoryBean();
        jobDetailFactory.setJobClass(ContractStatusJob.class);
        jobDetailFactory.setName("Qrtz_Contract_Job_Detail");
        jobDetailFactory.setDescription("Invoke contract job detail");
        jobDetailFactory.setDurability(true);
        return jobDetailFactory;
    }

    @Bean
    public CronTriggerFactoryBean trigger(JobDetail job) {
        CronTriggerFactoryBean trigger = new CronTriggerFactoryBean();
        trigger.setJobDetail(job);

        log.debug("Configuring trigger to fire based on cron {}", contractCron);
        trigger.setCronExpression(contractCron);
        trigger.setName("Qrtz_Contract_Trigger");
        return trigger;
    }
}

以下是上述文件中使用的AutowiringSpringBeanJobFactory：

import lombok.extern.slf4j.Slf4j;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

@Slf4j
public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final ApplicationContext context) {
        beanFactory = context.getAutowireCapableBeanFactory();
    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
        final Object job = super.createJobInstance(bundle);
        beanFactory.autowireBean(job);
        return job;
    }
}

这是与Spring Boot 1.5.8一起使用的quartz.properties正常工作。这是QuartzConfigurer中使用的属性文件：

    #============================================================================
# Configure Main Scheduler Properties
#============================================================================

org.quartz.scheduler.instanceName = MyClusteredScheduler
org.quartz.scheduler.instanceId = AUTO

#============================================================================
# Configure ThreadPool
#============================================================================

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 25
org.quartz.threadPool.threadPriority = 5

#============================================================================
# Configure JobStore
#============================================================================

org.quartz.jobStore.misfireThreshold = 60000

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.PostgreSQLDelegate
org.quartz.jobStore.useProperties = false
org.quartz.jobStore.dataSource = default
org.quartz.jobStore.tablePrefix = QRTZ_

org.quartz.jobStore.isClustered = true
org.quartz.jobStore.clusterCheckinInterval = 20000

#============================================================================
# Configure Datasources
#============================================================================

org.quartz.dataSource.default.driver = org.postgresql.Driver
org.quartz.dataSource.default.URL = jdbc:postgresql://localhost:5432/example
org.quartz.dataSource.default.user = postgres
org.quartz.dataSource.default.password = postgres
org.quartz.dataSource.default.maxConnections = 5
org.quartz.dataSource.default.validationQuery = select 0 from dual

启动应用程序时抛出异常：

我的数据库配置根本没有改变，它在Spring Boot 1.5.8下工作正常。

Answer 1

您必须添加C3P0依赖项：

<dependency>
    <groupId>com.mchange</groupId>
    <artifactId>c3p0</artifactId>
    <version>0.9.5.2</version>
</dependency>

Answer 2

配置Quartz以使用HikariCP（默认为c3p0）

# quartz.properties

org.quartz.dataSource.quartzDataSource.provider=hikaricp

Answer 3

有时我遇到同样的问题。显然是由于缺少'c3p0'依赖性。

https://mvnrepository.com/artifact/c3p0/c3p0
编译组：“ c3p0”，名称：“ c3p0”，版本：“ 0.9.1.2”

我已将以下依赖项添加到我的build.gradle文件中，然后刷新了依赖项。然后这个错误就消失了。

使用Quartz和Spring Boot 2
