quartz的api及数据库表映射解析

序

因为想本身扩展quartz的job以及trigger的查询方法，改成支持分页的，因此这里对着一些api查看下相应的表映射。

job

scheduler.getJobKeys(GroupMatcher.anyJobGroup());
scheduler.getJobDetail(JobKey.jobKey(name,group));

quartz-2.3.0-sources.jar!/org/quartz/impl/jdbcjobstore/StdJDBCDelegate.java

String SELECT_JOBS_IN_GROUP_LIKE = "SELECT " + COL_JOB_NAME + ", " + COL_JOB_GROUP
            + " FROM " + TABLE_PREFIX_SUBST + TABLE_JOB_DETAILS + " WHERE "
            + COL_SCHEDULER_NAME + " = " + SCHED_NAME_SUBST
            + " AND " + COL_JOB_GROUP + " LIKE ?";

直接查job_details表

trigger

scheduler.getTriggerKeys(GroupMatcher.triggerGroupEquals(group));
scheduler.getTrigger(TriggerKey.triggerKey(name,group));

quartz-2.3.0-sources.jar!/org/quartz/impl/jdbcjobstore/StdJDBCDelegate.java

String SELECT_TRIGGERS_IN_GROUP_LIKE = "SELECT "
            + COL_TRIGGER_NAME + ", " + COL_TRIGGER_GROUP + " FROM " + TABLE_PREFIX_SUBST + TABLE_TRIGGERS
            + " WHERE " + COL_SCHEDULER_NAME + " = " + SCHED_NAME_SUBST
            + " AND " + COL_TRIGGER_GROUP + " LIKE ?";

查TRIGGERS表

TRIGGERS表

• QRTZ_TRIGGERS

trigger信息的总表

• QRTZ_SIMPLE_TRIGGERS

simple trigger类型的详情表，经过trigger_name与总表关联

• QRTZ_CRON_TRIGGERS

cron trigger类型的详情表，经过trigger_name与总表关联

• QRTZ_BLOG_TRIGGERS

用户用JDBC自定义的Trigger类型的详情表
