默认情况,Quartz的触发器,调度,任务等信息都是放在内存中的,叫做 RAMJobStore。 好处是快速,坏处是一旦系统重启,那么信息就丢失了,就得全部从头来过。
所以Quartz还提供了另一个方式,可以把这些信息存放在数据库做,叫做 JobStoreTX。
好处是就算系统重启了,目前运行到第几次了这些信息都是存放在数据库中的,那么就可以继续原来的步伐把计划任务无缝地继续做下去。 坏处就是性能上比内存慢一些,毕竟数据库读取总是要慢一些的。
首先建表:
DROP DATABASE IF EXISTS quartz; CREATE DATABASE quartz DEFAULT CHARACTER SET utf8; USE quartz; DROP TABLE IF EXISTS QRTZ_FIRED_TRIGGERS; DROP TABLE IF EXISTS QRTZ_PAUSED_TRIGGER_GRPS; DROP TABLE IF EXISTS QRTZ_SCHEDULER_STATE; DROP TABLE IF EXISTS QRTZ_LOCKS; DROP TABLE IF EXISTS QRTZ_SIMPLE_TRIGGERS; DROP TABLE IF EXISTS QRTZ_SIMPROP_TRIGGERS; DROP TABLE IF EXISTS QRTZ_CRON_TRIGGERS; DROP TABLE IF EXISTS QRTZ_BLOB_TRIGGERS; DROP TABLE IF EXISTS QRTZ_TRIGGERS; DROP TABLE IF EXISTS QRTZ_JOB_DETAILS; DROP TABLE IF EXISTS QRTZ_CALENDARS; CREATE TABLE QRTZ_JOB_DETAILS ( SCHED_NAME VARCHAR(120) NOT NULL, JOB_NAME VARCHAR(100) NOT NULL, JOB_GROUP VARCHAR(100) NOT NULL, DESCRIPTION VARCHAR(250) NULL, JOB_CLASS_NAME VARCHAR(250) NOT NULL, IS_DURABLE VARCHAR(1) NOT NULL, IS_NONCONCURRENT VARCHAR(1) NOT NULL, IS_UPDATE_DATA VARCHAR(1) NOT NULL, REQUESTS_RECOVERY VARCHAR(1) NOT NULL, JOB_DATA BLOB NULL, PRIMARY KEY (SCHED_NAME,JOB_NAME,JOB_GROUP) ); CREATE TABLE QRTZ_TRIGGERS ( SCHED_NAME VARCHAR(120) NOT NULL, TRIGGER_NAME VARCHAR(100) NOT NULL, TRIGGER_GROUP VARCHAR(100) NOT NULL, JOB_NAME VARCHAR(100) NOT NULL, JOB_GROUP VARCHAR(100) NOT NULL, DESCRIPTION VARCHAR(250) NULL, NEXT_FIRE_TIME BIGINT(13) NULL, PREV_FIRE_TIME BIGINT(13) NULL, PRIORITY INTEGER NULL, TRIGGER_STATE VARCHAR(16) NOT NULL, TRIGGER_TYPE VARCHAR(8) NOT NULL, START_TIME BIGINT(13) NOT NULL, END_TIME BIGINT(13) NULL, CALENDAR_NAME VARCHAR(100) NULL, MISFIRE_INSTR SMALLINT(2) NULL, JOB_DATA BLOB NULL, PRIMARY KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP), FOREIGN KEY (SCHED_NAME,JOB_NAME,JOB_GROUP) REFERENCES QRTZ_JOB_DETAILS(SCHED_NAME,JOB_NAME,JOB_GROUP) ); CREATE TABLE QRTZ_SIMPLE_TRIGGERS ( SCHED_NAME VARCHAR(120) NOT NULL, TRIGGER_NAME VARCHAR(100) NOT NULL, TRIGGER_GROUP VARCHAR(100) NOT NULL, REPEAT_COUNT BIGINT(7) NOT NULL, REPEAT_INTERVAL BIGINT(12) NOT NULL, TIMES_TRIGGERED BIGINT(10) NOT NULL, PRIMARY KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP), FOREIGN KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP) REFERENCES QRTZ_TRIGGERS(SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP) ); CREATE TABLE QRTZ_CRON_TRIGGERS ( SCHED_NAME VARCHAR(120) NOT NULL, TRIGGER_NAME VARCHAR(100) NOT NULL, TRIGGER_GROUP VARCHAR(100) NOT NULL, CRON_EXPRESSION VARCHAR(100) NOT NULL, TIME_ZONE_ID VARCHAR(80), PRIMARY KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP), FOREIGN KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP) REFERENCES QRTZ_TRIGGERS(SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP) ); CREATE TABLE QRTZ_SIMPROP_TRIGGERS ( SCHED_NAME VARCHAR(120) NOT NULL, TRIGGER_NAME VARCHAR(100) NOT NULL, TRIGGER_GROUP VARCHAR(100) NOT NULL, STR_PROP_1 VARCHAR(512) NULL, STR_PROP_2 VARCHAR(512) NULL, STR_PROP_3 VARCHAR(512) NULL, INT_PROP_1 INT NULL, INT_PROP_2 INT NULL, LONG_PROP_1 BIGINT NULL, LONG_PROP_2 BIGINT NULL, DEC_PROP_1 NUMERIC(13,4) NULL, DEC_PROP_2 NUMERIC(13,4) NULL, BOOL_PROP_1 VARCHAR(1) NULL, BOOL_PROP_2 VARCHAR(1) NULL, PRIMARY KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP), FOREIGN KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP) REFERENCES QRTZ_TRIGGERS(SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP) ); CREATE TABLE QRTZ_BLOB_TRIGGERS ( SCHED_NAME VARCHAR(120) NOT NULL, TRIGGER_NAME VARCHAR(100) NOT NULL, TRIGGER_GROUP VARCHAR(100) NOT NULL, BLOB_DATA BLOB NULL, PRIMARY KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP), FOREIGN KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP) REFERENCES QRTZ_TRIGGERS(SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP) ); CREATE TABLE QRTZ_CALENDARS ( SCHED_NAME VARCHAR(120) NOT NULL, CALENDAR_NAME VARCHAR(100) NOT NULL, CALENDAR BLOB NOT NULL, PRIMARY KEY (SCHED_NAME,CALENDAR_NAME) ); CREATE TABLE QRTZ_PAUSED_TRIGGER_GRPS ( SCHED_NAME VARCHAR(120) NOT NULL, TRIGGER_GROUP VARCHAR(100) NOT NULL, PRIMARY KEY (SCHED_NAME,TRIGGER_GROUP) ); CREATE TABLE QRTZ_FIRED_TRIGGERS ( SCHED_NAME VARCHAR(120) NOT NULL, ENTRY_ID VARCHAR(95) NOT NULL, TRIGGER_NAME VARCHAR(100) NOT NULL, TRIGGER_GROUP VARCHAR(100) NOT NULL, INSTANCE_NAME VARCHAR(100) NOT NULL, FIRED_TIME BIGINT(13) NOT NULL, SCHED_TIME BIGINT(13) NOT NULL, PRIORITY INTEGER NOT NULL, STATE VARCHAR(16) NOT NULL, JOB_NAME VARCHAR(100) NULL, JOB_GROUP VARCHAR(100) NULL, IS_NONCONCURRENT VARCHAR(1) NULL, REQUESTS_RECOVERY VARCHAR(1) NULL, PRIMARY KEY (SCHED_NAME,ENTRY_ID) ); CREATE TABLE QRTZ_SCHEDULER_STATE ( SCHED_NAME VARCHAR(120) NOT NULL, INSTANCE_NAME VARCHAR(100) NOT NULL, LAST_CHECKIN_TIME BIGINT(13) NOT NULL, CHECKIN_INTERVAL BIGINT(13) NOT NULL, PRIMARY KEY (SCHED_NAME,INSTANCE_NAME) ); CREATE TABLE QRTZ_LOCKS ( SCHED_NAME VARCHAR(120) NOT NULL, LOCK_NAME VARCHAR(40) NOT NULL, PRIMARY KEY (SCHED_NAME,LOCK_NAME) ); commit;
