崛起于Springboot2.0.X之页面统一操作Quartz所有定时任务何时启动（47）

    （记得来开源中国关注我哟！如果博客被我发现有不好的地方，都会优化更新的，所以关注我呦，嘻嘻）

      技术栈：Springboot2.0.X（2.1.X也可以）+ Quartz +FastMybatis (自认为比mybatis-plus更方便的框架) + Hutool + lombok

      序言：之前公司有一个需求说是可以通过一个界面来操作定时任务的时间、包括修改、启动、关闭等功能，而不是在代码中写死，那个时候从网上找了很久都没有找到，博客都特别初级，只能算是入门的后来就不了了之了，目前已经实现开发出这套功能，公开一下，我也希望能够帮助更多的人在企业更加快速的实现该功能，如图：

       然后我们看一下，新增定时任务配置截图：

    这个功能也有批量暂停定时任务的功能、立即恢复、以及执行，当然还有定时任务启动时的日志记录，如图：

    所以接下来就进入开发阶段，由于前端页面是用vue写的，我就不把前端代码弄出来了，反而这样会让大家使用起来比较费力，所以我们就不用vue进行测试了，只用后段自己生成数据来测试就可以了，也能够达到目的的。

3、mysql表结构

CREATE TABLE `schedule_job` (
  `job_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '任务id',
  `bean_name` varchar(200) DEFAULT NULL COMMENT 'spring bean名称',
  `method_name` varchar(100) DEFAULT NULL COMMENT '方法名',

  PRIMARY KEY (`job_id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT COMMENT='定时任务'


CREATE TABLE `schedule_job_log` (

  PRIMARY KEY (`log_id`),
  KEY `job_id` (`job_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT COMMENT='定时任务日志'

4、实体类

import lombok.Data;
import javax.persistence.*;
import java.io.Serializable;
import java.util.Date;

@Data
@Table(name = "schedule_job")
public class ScheduleJobEntity implements Serializable {
    private static final long serialVersionUID = 1L;
    public static final String JOB_PARAM_KEY = "JOB_PARAM_KEY"; //任务调度参数key
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "job_id")
    private Long jobId;            //任务id
    @Column(name = "bean_name")
    private String beanName;       //spring bean名称

    @Column(name = "cron_expression")
    private String cronExpression; //cron表达式
    @Column(name = "status")
    private Integer status;        //任务状态
    @Column(name = "remark")
    private String remark;         //备注
    @Column(name = "create_time")
    private Date createTime;       //创建时间
}

import lombok.Data;

import javax.persistence.*;
import java.io.Serializable;
import java.util.Date;

/**

 */
@Data
@Table(name = "schedule_job_log")
public class ScheduleJobLogEntity implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "log_id")
    private Long logId;       //日志id

    @Column(name = "times")
    private Integer times;    //耗时(单位：毫秒)
    @Column(name = "create_time")
    private Date createTime;  //创建时间
}

    请求接口统一返回实体类

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.ToString;
@Data
@AllArgsConstructor
@ToString
public class ResultData {
    private boolean success;
    private String code;
    private String message;
    private Object data;

    public ResultData() {
        this.success = true;
        this.code = "200";
    }
}

5、Util层

        这一层代码大家看不明白没有关系，毕竟这些都是工具类里面的，不是我们开发日常编码那种，所以只需要配置一次就好啦，正常开发我们就直接跳过第五步就好了。

   }

   @Override
    public int updateBatch(Long[] jobIds, int status){
       Map<String, Object> map = new HashMap<>();
       map.put("list", jobIds);
       map.put("status", status);
       return schedulerJobDao.updateBatchStatus(map);
    }
    
   @Override
   @Transactional
    public void run(Long[] jobIds) {
       for(Long jobId : jobIds){
          ScheduleUtils.run(scheduler, queryObject(jobId));
       }
    }

   @Override
   @Transactional
    public void pause(Long[] jobIds) {
        for(Long jobId : jobIds){
          ScheduleUtils.pauseJob(scheduler, jobId);
       }
       updateBatch(jobIds, 1);
    }

   @Override
   @Transactional
    public void resume(Long[] jobIds) {
       for(Long jobId : jobIds){
          ScheduleUtils.resumeJob(scheduler, jobId);
       }
       updateBatch(jobIds, 0);
    }

   @Override
   public ResultData listJob(int pageIndex, int pageSize) {
      ResultData resultData = new ResultData();
      //查询列表数据
      Query query = new Query();
      query.page(1,10);

      List<ScheduleJobEntity> jobList = schedulerJobDao.list(query);

      long total = schedulerJobDao.getCount(query);

      Map<String,Object> map = new HashMap<>();
      map.put("total",total);
      map.put("list",jobList);

      resultData.setData(map);
      return resultData;
   }

   @Override
   public ResultData queryLogObject(Long jobId) {
      ResultData resultData = new ResultData();
      resultData.setData(jobLogDao.getById(jobId));
      return resultData;
   }

   @Override
   public void saveLog(ScheduleJobLogEntity log) {
      jobLogDao.save(log);
   }

   @Override
   public ResultData listLog(int pageIndex, int pageSize) {
      ResultData resultData = new ResultData();

      //查询列表数据
      Query query = new Query();
      query.page(pageIndex,pageSize);

      List<ScheduleJobLogEntity> jobList = jobLogDao.list(query);

      long total = jobLogDao.getCount(query);

      Map<String,Object> map = new HashMap<>();
      map.put("total",total);
      map.put("list",jobList);

      resultData.setData(map);

      return resultData;
   }
}

8、Controller层

@RestController
@RequestMapping("/schedule")
public class ScheduleJobController {

    @Autowired
    private ScheduleJobService scheduleJobService;

    /**
     * 定时任务列表
     */
    @RequestMapping("/list")
    public ResultData list() {
        return scheduleJobService.listJob(1,10);
    }

    /**
     * 定时任务信息
     */
    @RequestMapping("/info/{jobId}")
    public ResultData info(@PathVariable("jobId") Long jobId) {
        ScheduleJobEntity schedule = scheduleJobService.queryObject(jobId);
        ResultData resultData = new ResultData();
        resultData.setData(schedule);

        return resultData;

    }

    /**
     * 保存定时任务 @RequestBody ScheduleJobEntity scheduleJob
     */
    @RequestMapping("/save")
    public ResultData save() {

        //先测试编写一个临时ScheduleJobEntity，毕竟后端页面不会写
        ScheduleJobEntity jobEntity = createJob();
        ValidatorUtils.validateEntity(jobEntity);

        scheduleJobService.save(jobEntity);

        return new ResultData();
    }

    /**
     * 修改定时任务
     */
    @RequestMapping("/update")
    public ResultData update(@RequestBody ScheduleJobEntity scheduleJob) {
        ValidatorUtils.validateEntity(scheduleJob);

        scheduleJobService.update(scheduleJob);
        return new ResultData();
    }

    /**
     * 删除定时任务
     */
    @RequestMapping("/delete")
    public ResultData delete(@RequestBody Long[] jobIds) {
        scheduleJobService.deleteBatch(jobIds);
        return new ResultData();
    }

    /**
     * 立即执行任务
     */
    @RequestMapping("/run")
    public ResultData run(@RequestBody Long[] jobIds) {
        scheduleJobService.run(jobIds);
        return new ResultData();
    }

    /**
     * 暂停定时任务
     */
    @RequestMapping("/pause")
    public ResultData pause(@RequestBody Long[] jobIds) {
        scheduleJobService.pause(jobIds);
        return new ResultData();
    }

    /**
     * 恢复定时任务
     */
    @RequestMapping("/resume")
    public ResultData resume(@RequestBody Long[] jobIds) {
        scheduleJobService.resume(jobIds);
        return new ResultData();
    }

    /**
     * 定时任务日志列表
     */
    @RequestMapping("/log/list")
    public ResultData listLog() {
       return scheduleJobService.listLog(1,10);
    }

    /**
     * 定时任务日志信息查询
     */
    @RequestMapping("/log/info/{logId}")
    public ResultData infoLog(@PathVariable("logId") Long logId) {
        return scheduleJobService.queryLogObject(logId);
    }

    public static ScheduleJobEntity createJob(){
        ScheduleJobEntity jobEntity = new ScheduleJobEntity();
        jobEntity.setBeanName("mytask");
        jobEntity.setCreateTime(new Date());
        jobEntity.setMethodName("firstTask");
        jobEntity.setCronExpression("0/10 * * * * ?");
        jobEntity.setParams(null);
        jobEntity.setStatus(1);
        jobEntity.setRemark("测试该定时任务的执行");
        return jobEntity;
    }
}

9、定时任务

        该类涉及到@Component(value = "mytask")和方法名都将被前端页面使用，使用这两个属性值定位到何时执行该定时任务。

import org.springframework.stereotype.Component;

/**
 * @Author:MuJiuTian
 * @Description: 页面控制定时任务的触发时间、开启和关闭都要有定时任务
 * @Date: Created in 下午2:06 2019/8/27
 */
@Component(value = "mytask")
public class MyTask {

    public void firstTask(){
        //再这个方法中执行task业务逻辑
        System.out.println("该定时任务由前台页面控制何时启动");
    }
}

10、启动测试

        谨记，启动类，千万不要添加@MapperScan(),因为集成了FastMybatis框架，已经自动封装了。如果大家不喜欢这个框架的话，也可以使用Mybatis或者流行的Mybatis-plus或者TKMybatis、EasyMybatis等等框架。

        测试接口：http://localhost:8081/schedule/save，我的端口是8081的。

         结果如图已经触发我们刚刚写的定时任务了：

     成功啦！不喜欢用FastMybatis的话用其他框架操作mysql吧，毕竟我不太喜欢用mybatis-plus，毕竟需要多写代码。
