Quartz的分布式功能化设计

文章目录

quartz分布式自带的管理表位置：建表语句所在位置: quartz-x.y.z.jar ， org.quartz.imp.jdbcjobstore路径下，这边只介绍Mysql的，文件名为 table_mysql_innodb.sql 。在sql文件中一共有11张表。

shell 复制代码 
1.qrtz_blob_triggers
2.qrtz_cron_triggers
3.qrtz_simple_triggers
4.qrtz_simprop_triggers
5.qrtz_fired_triggers
6.qrtz_triggers
7.qrtz_job_details
8.qrtz_calendars
9.qrtz_paused_trigger_grps
10.qrtz_scheduler_state
11.qrtz_locks

使用场景：所有的任务都是针对业务来的，并非公共调度平台，所以侵入式代码库是可以的。

主体功能

  1. 通过新增数据库管理表(SYS_QUARTZ_JOB)，来明确任务基本信息
  2. 任务类型都是定时型；
  3. 支持新增任务，只能存在一个在用的同名任务；
  4. 支持暂停任务；
  5. 支持恢复暂停的任务；
  6. 支持更新任务，数据库管理表是更新操作，而Quartz框架是进行了先删除在重建进行更新；
  7. 支持删除任务；
  8. 支持即时执行一次任务。

API

  1. 新建Quartz任务：addJob(@Validated @RequestBody QuartzJobDTO quartzJobDTO,HttpServletRequest req)
  2. 立即执行任务：runJobNow(@NotNull(message = "jobId不能为空") Long jobId, HttpServletRequest req)
  3. 删除Quartz任务：deleteJob(@NotNull(message = "jobId不能为空") Long jobId, HttpServletRequest req)
  4. 恢复Quartz任务（针对暂停的任务）：resumeJob(@NotBlank(message = "任务完整类名不能为空") @Size(max = 250, message = "最大长度250") String jobClassName, HttpServletRequest req)
  5. 暂停Quartz任务：pauseJob(@NotBlank(message = "任务完整类名不能为空") @Size(max = 250, message = "最大长度250") String jobClassName, HttpServletRequest req)
  6. 查询未删除的Quartz任务 分页式：quartzJoblist(@Validated @RequestBody QuartzJobPageDTO quartzJobPageDto)
  7. 更新Quartz任务（采用先删除后增加的方式处理）：updateJob(@Validated @RequestBody UpdateQuartzJobDTO quartzJob, HttpServletRequest req)
