本章任务
1、Spring整合Quartz
2、读取数据库中表达式启动定时任务1（每5s执行）
3、更改定时任务状态（启用/禁用），定时任务1停止
4、读取数据库中表达式启动定时任务2（每5s执行），在对应作业类中打印定时任务2携带的参数
5、读取数据库中表达式启动定时任务3（每5s执行改成每20s执行），更改数据库定时任务表达式，定时任务3对应执行策略相应发生改变。
Spring整合Quartz
必须使用quartz调度框架内置表
进入quartz的官网，点击Downloads，
下载后在目录\docs\dbTables下有常用数据库创建quartz表的脚本，例如：“tables_mysql.sql”
导入数据库
ps: table_mysql_innodb.sql 这个是针对 mysql中innodb 这个引擎的，如果你使用的是这个引擎就导入这个吧
quartz 内置表结构：
自定义的业务表
-- 注意：job_name存放的任务类的全路径，在quartz中通过jobName和jobGroup来确定trigger的唯一性，所以这两列为联合唯一索引
create table t_schedule_trigger
(
id int primary key auto_increment, -- ID
cron varchar(200) not null, -- 时间表达式
status char(1) not null, -- 使用状态 0：禁用 1：启用
job_name varchar(200) not null, -- 任务名称
job_group varchar(200) not null, -- 任务分组
unique index(job_name,job_group)
);
-- 额外添加到任务中的参数
create table t_schedule_trigger_param
(
param_id int primary key auto_increment, -- ID
name varchar(200) not null, -- 参数名
value varchar(512), -- 参数值
schedule_trigger_id int not null, -- 外键：引用t_schedule_trigger(id)
foreign key(schedule_trigger_id) references t_schedule_trigger(id)
);
案例中需要观察表数据变化的表
-- 自定义的业务表
SELECT * FROM t_schedule_trigger;
SELECT * FROM t_schedule_trigger_param;
-- quartz调度框架自带的表
SELECT * FROM qrtz_scheduler_state;
SELECT * FROM qrtz_cron_triggers;
SELECT * FROM qrtz_simple_triggers
SELECT * FROM qrtz_triggers;
SELECT * FROM qrtz_job_details;
创建springboot项目
这是此处项目所要用到的启动器
导入pom依赖
maven中还需添加：

修改quartz数据源为 Druid
说明：
quartz 需要用到数据库连接池，Quartz 2.0 以前默认使用 DBCP。Quartz 2.0 以后 默认C3P0（包含2.0）。下面我们要将数据源修改为 Druidps:Druid的有自带监控系统...所以大家都在用，但是呢：配置换源很繁琐。如以下
基本步骤：
（1）导入依赖（上面已经导入了）
（2）导入DruidConnectionProvider.java
（3）修改quartz.properties配置
导入DruidConnectionProvider.java
package com.wxm.quartz02.util;

注意修改
我这里血的示范！！！
报错解决思路：
错误体现
-
java.lang.IllegalStateException: Failed to load ApplicationContext
-
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘springTaskByQaurtz’: Unsatisfied dependency expressed
-
Caused by: java.lang.ClassNotFoundException:

Caused by:
java.lang.ClassNotFoundException:

发现越往下越体现突破点，发现找不到DruidConnectionProvider这个类！！！！？？，仔细想想这个类是连接数据库数据用的
而它又是读取它的类quartz.properties
仔细想想突然???
这里配置：

Spring自带定时任务每10s执行一次，查询自定义触发器表，获取到具体的作业类及任务表达式，quartz的任务为每5s执行一次，所以打印如上
更改定时任务状态
更改数据库调度器表t_schedule_trigger的state状态
把 三条的status=1改为0，全部关闭状态
禁用后
定时任务中携带参数
把 第二条的status=0改为1，开启状态
MyJob1
package com.wxm.quartz02.job;
import com.wxm.quartz02.service.TriggerParamService;
import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
@Slf4j
public class MyJob1 implements Job {
@Autowired
private TriggerParamService scheduleTriggerParamService;
@Override
public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
JobDetail jobDetail =
jobExecutionContext.getJobDetail();
JobDataMap jobDataMap = jobDetail.getJobDataMap();
System.out.println(new Date().toLocaleString()+"-->携带参数个数:"+jobDataMap.size());
}
}
更改定时任务规则
把 第3条的status=0改为1，开启状态
MyJob2
package com.wxm.quartz02.job;
import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.springframework.stereotype.Component;

JobDataMap jobDataMap = jobDetail.getJobDataMap();
System.out.println(new Date().toLocaleString()+"-->MyJobParam2参数传递name="+jobDataMap.get("name")+",score="+
jobDataMap.get("score"));
}
}

其实意思就是它找不到你的界面，因为他默认读取的是templates下的跟目录
所以我们需要在pom.xml文件里面添加一段配置，然后它就会找到相对应的界面了，这样我们运行的时候就会成功了
代码如下：
<resource>
<directory>src/main/resources</directory>
</resource>
