• quartz框架实现job之后无法使用@Value@Autowired注入问题


    quartz框架使用@Autowired为null问题,quartz框架默认是不交给spring管理的,要想实现交给spring就需要自己配置JobFactory,QuartzConfig

    1.依赖

    <!--quartz-->
            <dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz</artifactId>
                <version>2.3.2</version>
            </dependency>

    2.JobFactory

    import org.quartz.spi.TriggerFiredBundle;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.scheduling.quartz.SpringBeanJobFactory;
    
    @Configuration
    public class MyJobFactory extends SpringBeanJobFactory {
    
        @Autowired
        private AutowireCapableBeanFactory capableBeanFactory;
    
        @Override
        protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception{
            //调用父类的方法
            Object jobInstance = super.createJobInstance(bundle);
            //进行注入
            capableBeanFactory.autowireBean(jobInstance);
            return jobInstance;
        }
    }

    3.QuartzConfig

    import org.quartz.Scheduler;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.scheduling.quartz.SchedulerFactoryBean;
    
    @Configuration
    public class QuartzConfig {
        @Autowired
        private MyJobFactory myJobFactory;
    
        @Bean
        public SchedulerFactoryBean schedulerFactoryBean() {
            SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
            schedulerFactoryBean.setJobFactory(myJobFactory);
            return schedulerFactoryBean;
        }
    
        @Bean
        public Scheduler scheduler() {
            return schedulerFactoryBean().getScheduler();
        }
    
    
    }

    4.Quartz任务管理类

    import com.oigit.api.utils.DateUtil;
    import org.quartz.*;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Component;
    
    import java.text.SimpleDateFormat;
    
    import static org.quartz.TriggerBuilder.newTrigger;
    
    @Component
    public class QuartzManager {
        @Autowired
        private Scheduler scheduler;
    
        /**

         */  
        @SuppressWarnings({ "unchecked", "rawtypes" })  
        public void addJob(String jobName, String jobGroupName, String triggerName, String triggerGroupName, Class jobClass, String date,Long id) {
            try {
                // 任务名,任务组,任务执行类
                JobDetail jobDetail = JobBuilder.newJob(jobClass).withIdentity(jobName, jobGroupName).build();
                jobDetail.getJobDataMap().put("id",id);
                // 触发器
                SimpleTrigger trigger = (SimpleTrigger) newTrigger()
                        .withIdentity(triggerName, triggerGroupName)
                        .startAt(new SimpleDateFormat("yyyy-MM-dd HH:mm").parse(DateUtil.format(date, "yyyy-MM-dd HH:mm")))                     // some Date
                        .forJob(jobName, jobGroupName)                 // identify job with name, group strings
                        .build();
                // 调度容器设置JobDetail和Trigger
                scheduler.scheduleJob(jobDetail, trigger);
                // 启动
                if (!scheduler.isShutdown()) {
                    scheduler.start();
                }
            } catch (Exception e) {  
                throw new RuntimeException(e);  
            }  
        }  
    
        /**

         */  
        public void modifyJobTime(String jobName, String jobGroupName, String triggerName, String triggerGroupName, String date) {
            try {  
                TriggerKey triggerKey = TriggerKey.triggerKey(triggerName, triggerGroupName);
                SimpleTrigger trigger = (SimpleTrigger) scheduler.getTrigger(triggerKey);
                if (trigger == null) {
                    return;  
                }
                /** 方式一 :调用 rescheduleJob 开始 */
                // 触发器

                        .withIdentity(triggerName, triggerGroupName)

                    Class<? extends Job> jobClass = jobDetail.getJobClass();
                    removeJob(jobName, jobGroupName, triggerName, triggerGroupName);
                    addJob(jobName, jobGroupName, triggerName, triggerGroupName, jobClass, cron);*/
            } catch (Exception e) {  
                throw new RuntimeException(e);  
            }  
        }  
    
        /**

         * @param triggerGroupName 
         */  
        public void removeJob(String jobName, String jobGroupName,String triggerName, String triggerGroupName) {
            try {  
                TriggerKey triggerKey = TriggerKey.triggerKey(triggerName, triggerGroupName);
                scheduler.pauseTrigger(triggerKey);// 停止触发器
                scheduler.unscheduleJob(triggerKey);// 移除触发器

            } catch (Exception e) {
                throw new RuntimeException(e);  
            }  
        }  
    
        /** 
         * @Description:启动所有定时任务

        public void startJobs() {
            try {  
                scheduler.start();
            } catch (Exception e) {
                throw new RuntimeException(e);  
            }  
        }  
    
        /** 
         * @Description:关闭所有定时任务 
         */  
        public void shutdownJobs() {
            try {  
                if (!scheduler.isShutdown()) {
                    scheduler.shutdown();
                }  
            } catch (Exception e) {  
                throw new RuntimeException(e);  
            }  
        }  
    }

    5.业务逻辑执行的Job

    import com.alibaba.fastjson.JSON;
    import com.alibaba.fastjson.JSONObject;
    import com.oigit.api.common.Constant;
    import com.oigit.api.model.Wage;
    import com.oigit.api.model.WageDetail;
    import com.oigit.api.repository.UserRepository;
    import com.oigit.api.repository.WageDetailRepository;
    import com.oigit.api.repository.WageRepository;
    import com.oigit.api.service.TokenService;
    import com.oigit.api.utils.HttpUtil;
    import lombok.extern.slf4j.Slf4j;
    import org.apache.commons.lang.StringUtils;
    import org.quartz.Job;
    import org.quartz.JobDataMap;
    import org.quartz.JobExecutionContext;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.stereotype.Service;
    
    import java.net.URLEncoder;
    import java.util.List;
    import java.util.Optional;
    
    @Slf4j
    @Service
    public class SendWageJob implements Job {
        @Value("${trust.uri}")
        private String trustUri;
    
        @Autowired
        private UserRepository userRepository;
    
        @Override
        public void execute(JobExecutionContext jobExecutionContext) {
            JobDataMap dataMap = jobExecutionContext.getJobDetail().getJobDataMap();
            long wageId = dataMap.getLongValue("id");
            //业务逻辑
      }
    }

    6.利用任务管理类添加任务

    this.quartzManager.addJob("jobName-"+RandomStringUtils.randomAlphanumeric(32),"wageJobGroup","triggerName-"+RandomStringUtils.randomAlphanumeric(32),"wageTriggerGroup", SendWageJob.class,date,id);
