本章任務(wù)
1、Spring整合Quartz
2、讀取數(shù)據(jù)庫中表達(dá)式啟動定時(shí)任務(wù)1（每5s執(zhí)行）
3、更改定時(shí)任務(wù)狀態(tài)（啟用/禁用），定時(shí)任務(wù)1停止
4、讀取數(shù)據(jù)庫中表達(dá)式啟動定時(shí)任務(wù)2（每5s執(zhí)行），在對應(yīng)作業(yè)類中打印定時(shí)任務(wù)2攜帶的參數(shù)
5、讀取數(shù)據(jù)庫中表達(dá)式啟動定時(shí)任務(wù)3（每5s執(zhí)行改成每20s執(zhí)行），更改數(shù)據(jù)庫定時(shí)任務(wù)表達(dá)式，定時(shí)任務(wù)3對應(yīng)執(zhí)行策略相應(yīng)發(fā)生改變。
Spring整合Quartz
必須使用quartz調(diào)度框架內(nèi)置表
進(jìn)入quartz的官網(wǎng)，點(diǎn)擊Downloads，
下載后在目錄\docs\dbTables下有常用數(shù)據(jù)庫創(chuàng)建quartz表的腳本，例如：“tables_mysql.sql”
導(dǎo)入數(shù)據(jù)庫
ps: table_mysql_innodb.sql 這個(gè)是針對 mysql中innodb 這個(gè)引擎的，如果你使用的是這個(gè)引擎就導(dǎo)入這個(gè)吧
quartz 內(nèi)置表結(jié)構(gòu)：
自定義的業(yè)務(wù)表
-- 注意：job_name存放的任務(wù)類的全路徑，在quartz中通過jobName和jobGroup來確定trigger的唯一性，所以這兩列為聯(lián)合唯一索引 create table t_schedule_trigger (id int primary key auto_increment, -- IDcron varchar(200) not null, -- 時(shí)間表達(dá)式status char(1) not null, -- 使用狀態(tài) 0：禁用 1：啟用job_name varchar(200) not null, -- 任務(wù)名稱job_group varchar(200) not null, -- 任務(wù)分組 unique index(job_name,job_group) );-- 額外添加到任務(wù)中的參數(shù) create table t_schedule_trigger_param (param_id int primary key auto_increment, -- IDname varchar(200) not null, -- 參數(shù)名value varchar(512), -- 參數(shù)值schedule_trigger_id int not null, -- 外鍵：引用t_schedule_trigger(id)foreign key(schedule_trigger_id) references t_schedule_trigger(id) );案例中需要觀察表數(shù)據(jù)變化的表
-- 自定義的業(yè)務(wù)表 SELECT * FROM t_schedule_trigger; SELECT * FROM t_schedule_trigger_param;-- quartz調(diào)度框架自帶的表 SELECT * FROM qrtz_scheduler_state; SELECT * FROM qrtz_cron_triggers; SELECT * FROM qrtz_simple_triggers SELECT * FROM qrtz_triggers; SELECT * FROM qrtz_job_details;創(chuàng)建springboot項(xiàng)目
這是此處項(xiàng)目所要用到的啟動器
導(dǎo)入pom依賴
maven中還需添加：

說明：
quartz 需要用到數(shù)據(jù)庫連接池，Quartz 2.0 以前默認(rèn)使用 DBCP。Quartz 2.0 以后 默認(rèn)C3P0（包含2.0）。下面我們要將數(shù)據(jù)源修改為 Druidps:Druid的有自帶監(jiān)控系統(tǒng)...所以大家都在用，但是呢：配置換源很繁瑣。如以下
基本步驟：
（1）導(dǎo)入依賴（上面已經(jīng)導(dǎo)入了）
（2）導(dǎo)入DruidConnectionProvider.java
（3）修改quartz.properties配置
導(dǎo)入DruidConnectionProvider.java

(這樣就不會加載自帶的properties文件)
此文件的內(nèi)容主要分為：scheduler，ThreadPool，JobStore，plugin，Datasources等部分，覆蓋properties文件的目的是覆蓋默認(rèn)的數(shù)據(jù)源，更換為druid的數(shù)據(jù)配置
注意修改
我這里血的示范！！！

發(fā)現(xiàn)越往下越體現(xiàn)突破點(diǎn)，發(fā)現(xiàn)找不到DruidConnectionProvider這個(gè)類！！！！？？，仔細(xì)想想這個(gè)類是連接數(shù)據(jù)庫數(shù)據(jù)用的
而它又是讀取它的類quartz.properties

Spring自帶定時(shí)任務(wù)每10s執(zhí)行一次，查詢自定義觸發(fā)器表，獲取到具體的作業(yè)類及任務(wù)表達(dá)式，quartz的任務(wù)為每5s執(zhí)行一次，所以打印如上
更改定時(shí)任務(wù)狀態(tài)
更改數(shù)據(jù)庫調(diào)度器表t_schedule_trigger的state狀態(tài)
把 三條的status=1改為0，全部關(guān)閉狀態(tài)
禁用后
定時(shí)任務(wù)中攜帶參數(shù)
把 第二條的status=0改為1，開啟狀態(tài)

更改定時(shí)任務(wù)規(guī)則
把 第3條的status=0改為1，開啟狀態(tài)

界面版CURD
最終效果
quartzController
其實(shí)意思就是它找不到你的界面，因?yàn)樗J(rèn)讀取的是templates下的跟目錄
所以我們需要在pom.xml文件里面添加一段配置，然后它就會找到相對應(yīng)的界面了，這樣我們運(yùn)行的時(shí)候就會成功了
代碼如下：
