SpringBoot+quartz实现定时任务的创建、删除、查询操作

1、在pom.xml文件中导入quartz的依赖

            org.springframework.boot
            spring-boot-starter-quartz
        

2、配置quartz的数据源等操作

package com.train.batch.config;

import jakarta.annotation.Resource;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import javax.sql.DataSource;
import java.io.IOException;

@Configuration
public class SchedulerConfig {

    @Resource
    private MyJobFactory myJobFactory;

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(@Qualifier("dataSource") DataSource dataSource) throws IOException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setDataSource(dataSource);
        factory.setJobFactory(myJobFactory);
        // 启动之后2秒后可以执行
        factory.setStartupDelay(2);
        return factory;
    }
}

需要对父类的方法进行重写。 

package com.train.batch.config;

import jakarta.annotation.Resource;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;
import org.springframework.stereotype.Component;

@Component
public class MyJobFactory extends SpringBeanJobFactory {

    @Resource
    private AutowireCapableBeanFactory beanFactory;

    /**
     * 这里覆盖了super的createJobInstance方法，对其创建出来的类再进行autowire。
     */
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        Object jobInstance = super.createJobInstance(bundle);
        beanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}

 3、并发执行：上一周期还没执行完，下一周期又开始了

禁止任务并发执行，只需要在类上加一个注解（@DisallowConcurrentExecution）

4、controller类，

做调度问题，不应该把任务写在配置类里面，应该用控制台增加，以下的文件直接拿来用就行。

package com.train.batch.job;

import com.train.batch.req.CronJobReq;
import com.train.batch.resp.CronJobResp;
import com.train.common.resp.CommonResp;

import org.quartz.*;
import org.quartz.impl.matchers.GroupMatcher;
import org.quartz.impl.triggers.CronTriggerImpl;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;


@RestController
@RequestMapping(value = "/admin/job")
public class JobController {

    private static Logger LOG = LoggerFactory.getLogger(JobController.class);

    @Autowired
    private SchedulerFactoryBean schedulerFactoryBean;

    @RequestMapping(value = "/run")
    public CommonResp
