一、准备工作
1. 在maven的pom文件中添加Quartz的Jar坐标
org.quartz-scheduler quartz 2.2.1 org.quartz-scheduler quartz-jobs 2.2.1
2. 在web.xml中添加quartz的监听器
org.quartz.ee.servlet.QuartzInitializerListener
3. 添加quartz.properties配置文件
# Configure Main Scheduler Properties org.quartz.scheduler.instanceName: dufy_test org.quartz.scheduler.instanceId = AUTO org.quartz.scheduler.rmi.export: false org.quartz.scheduler.rmi.proxy: false org.quartz.scheduler.wrapJobExecutionInUserTransaction: false # Configure ThreadPool org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount: 2 org.quartz.threadPool.threadPriority: 5 org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread: true org.quartz.jobStore.misfireThreshold: 60000 # Configure JobStore 持久化配置 #org.quartz.jobStore.class: org.quartz.simpl.RAMJobStore org.quartz.jobStore.class:org.quartz.impl.jdbcjobstore.JobStoreTX org.quartz.jobStore.driverDelegateClass:org.quartz.impl.jdbcjobstore.StdJDBCDelegate org.quartz.jobStore.useProperties:true # 是否集群 org.quartz.jobStore.isClustered = false # 表前缀 org.quartz.jobStore.tablePrefix:qrtz_ #org.quartz.jobStore.dataSource:qzDS # 下面是数据库的配置，交给Spring管理了 #org.quartz.dataSource.qzDS.driver:com.mysql.jdbc.Driver #org.quartz.dataSource.qzDS.URL:jdbc:mysql://localhost:3306/quartz_test #org.quartz.dataSource.qzDS.user:root #org.quartz.dataSource.qzDS.password:123 #org.quartz.dataSource.qzDS.maxConnection:10
4. 添加Spring配置：applicationContext-quartz.xml
5. 将Quartz自带的表导入Mysql
create table qrtz_job_details( sched_name varchar(120) not null, job_name varchar(80) not null, job_group varchar(80) not null, description varchar(120), job_class_name varchar(128) not null, is_durable integer not null, is_nonconcurrent integer not null, is_update_data integer not null, requests_recovery integer not null, job_data blob(2000), primary key (sched_name,job_name,job_group) ); create table qrtz_triggers( sched_name varchar(120) not null, trigger_name varchar(80) not null, trigger_group varchar(80) not null, job_name varchar(80) not null, job_group varchar(80) not null, description varchar(120), next_fire_time bigint, prev_fire_time bigint, priority integer, trigger_state varchar(16) not null, trigger_type varchar(8) not null, start_time bigint not null, end_time bigint, calendar_name varchar(80), misfire_instr smallint, job_data blob(2000), 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(80) not null, trigger_group varchar(80) not null, repeat_count bigint not null, repeat_interval bigint not null, times_triggered bigint 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(80) not null, trigger_group varchar(80) not null, cron_expression varchar(120) 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(200) NOT NULL, TRIGGER_GROUP VARCHAR(200) 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(80) not null, trigger_group varchar(80) not null, blob_data blob(2000), 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(80) not null, calendar blob(2000) not null, primary key (calendar_name) ); create table qrtz_fired_triggers( sched_name varchar(120) not null, entry_id varchar(95) not null, trigger_name varchar(80) not null, trigger_group varchar(80) not null, instance_name varchar(80) not null, fired_time bigint not null, sched_time bigint not null, priority integer not null, state varchar(16) not null, job_name varchar(80), job_group varchar(80), is_nonconcurrent integer, requests_recovery integer, primary key (sched_name,entry_id) ); create table qrtz_paused_trigger_grps( sched_name varchar(120) not null, trigger_group varchar(80) not null, primary key (sched_name,trigger_group) ); create table qrtz_scheduler_state( sched_name varchar(120) not null, instance_name varchar(80) not null, last_checkin_time bigint not null, checkin_interval bigint 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) );
6. 自己建立管理定时任务的表，我简单写了几个必须的属性
public class QuartzTask {
/*
* 这个类用于展示定时的任务，同时作用于定时任务的恢复、删除、中止；
**/
private Long jobId;
private String jobClass; //任务类的全限定类名
private String jobGroup; //任务组名
private String jobName; //任务名
private String triggerName; //任务触发器名
private String triggerGroupName; //任务触发器组名
private String cronExpr; //时间表达式
private Integer jobStatus; //任务状态
private String startTime; //任务开始时间
}7. 准备俩简单的Jsp页面用于添加定时任务和定时任务列表展示
大致效果如下：
1.写个任务类，本想做个功能，失败了，就简单控制台输出了
public class MyJob implements Job{
private static final Logger log = LoggerFactory.getLogger(MyJob.class);
@Override
public void execute(JobExecutionContext arg0) throws JobExecutionException {
log.info("MyJob is start ..................");
log.info("Hello quzrtz "+ new SimpleDateFormat("yyyy-MM-dd HH:mm:ss ").format(new Date()));
log.info("MyJob is end .....................");
}
}2. Controller层：QuartzController
@Controller
@RequestMapping("user/quartz")
public class QuartzController {
@Autowired
private QuartzTaskService quartzTaskService;
/**
* 添加定时任务
* */
@RequestMapping(value = "add",method = RequestMethod.POST)
public ModelAndView addQtz(QuartzTask qt){
try {
//1.成功启动定时任务
this.quartzTaskService.addQtz(qt);
//2.封装QuartzTask,执行保存
this.quartzTaskService.saveAddQtz(qt);
return new ModelAndView("success");
} catch (Exception e) {
e.printStackTrace();
}
return new ModelAndView("error");
}
/**
* 定时任务列表
* */
@RequestMapping(value = "list",method = RequestMethod.GET)
public ModelAndView listQtz(){
try {
//1.查询所有定时任务
Listlist = this.quartzTaskService.listQtz();
ModelAndView mv = new ModelAndView();
mv.addObject("qtzList",list);
mv.setViewName("quartz-list");
return mv;
} catch (Exception e) {
e.printStackTrace();
}
return new ModelAndView("error");
}
/**
* 删除定时任务
* */
@RequestMapping(value = "delete",method = RequestMethod.GET)
public ModelAndView deleteQtz(QuartzTask qt){
try {
// 执行删除
this.quartzTaskService.deleteQtz(qt);
// 根据id删除定时任务列表数据
this.quartzTaskService.deleteQtzTask(qt.getJobId());
return new ModelAndView("success");
} catch (Exception e) {
e.printStackTrace();
}
return new ModelAndView("error");
}
/**
* 中止定时任务
* */
@RequestMapping(value = "pause",method = RequestMethod.GET)
public ModelAndView pauseQtz(QuartzTask qt){
try {
// 执行中止
this.quartzTaskService.pauseQtz(qt);
return new ModelAndView("success");
} catch (Exception e) {
e.printStackTrace();
}
return new ModelAndView("error");
}
/**
* 恢复定时任务
* */
@RequestMapping(value = "resume",method = RequestMethod.GET)
public ModelAndView resumeQtz(QuartzTask qt){
try {
// 执行中止
this.quartzTaskService.resumeQtz(qt);
return new ModelAndView("success");
} catch (Exception e) {
e.printStackTrace();
}
return new ModelAndView("error");
}
}3. Service层：QuartzTaskServiceImpl
@Service
public class QuartzTaskServiceImpl implements QuartzTaskService {
@Autowired
private QuartzDao quartzDao;
@Autowired
private Scheduler scheduler;
@Override
public void addQtz(QuartzTask qt) {
try {
// 1.创建一个JobDetail实例，指定Quartz
String cla = qt.getJobClass();
Class clazz = Class.forName(cla);
JobDetail jobDetail = JobBuilder.newJob(clazz) // 任务执行类
.withIdentity(qt.getJobName(), qt.getJobGroup())// 任务名，任务组
.build();
CronScheduleBuilder builder = CronScheduleBuilder.cronSchedule(qt.getCronExpr());
// 2.创建Trigger(触发器)
Trigger trigger = TriggerBuilder.newTrigger().withIdentity(qt.getTriggerName(), qt.getTriggerGroupName())
.startNow().withSchedule(builder).build();
// 3.告诉调度器使用该触发器来安排作业
scheduler.scheduleJob(jobDetail, trigger);
// 4.启动
if (!scheduler.isShutdown()) {
scheduler.start();
}
} catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public void saveAddQtz(QuartzTask qt) {
qt.setJobId(1l);
qt.setJobStatus(1);
qt.setStartTime(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss ").format(new Date()));
this.quartzDao.saveAddQtz(qt);
}
@Override
public ListlistQtz() {
return quartzDao.listQtz();
}
@Override
public void deleteQtz(QuartzTask qt) {
try {
// 停止触发器
scheduler.pauseTrigger(TriggerKey.triggerKey(qt.getTriggerName(), qt.getTriggerGroupName()));
// 移除触发器
scheduler.unscheduleJob(TriggerKey.triggerKey(qt.getTriggerName(), qt.getTriggerGroupName()));
// 删除任务
scheduler.deleteJob(JobKey.jobKey(qt.getJobName(), qt.getJobGroup()));
} catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public void deleteQtzTask(Long jobId) {
this.quartzDao.deleteQtzTask(jobId);
}
@Override
public void pauseQtz(QuartzTask qt) {
try {
scheduler.pauseJob(JobKey.jobKey(qt.getJobName(), qt.getJobGroup()));
} catch (SchedulerException e) {
e.printStackTrace();
}
}
@Override
public void resumeQtz(QuartzTask qt) {
try {
scheduler.resumeJob(JobKey.jobKey(qt.getJobName(), qt.getJobGroup()));
} catch (SchedulerException e) {
e.printStackTrace();
}
}
}4. 与数据库交互的QuartzTask.xml文件
INSERT INTO quartz
(job_id,job_class,job_group,job_name,trigger_name,trigger_groupName,cron_expr,job_status,start_time)
VALUES(#{jobId},#{jobClass},#{jobGroup},#{jobName},#{triggerName},#{triggerGroupName},#{cronExpr},#{jobStatus},#{startTime});
select * from quartz;
DELETE from quartz where job_id = #{jobId};
我这里只做了简单实现，还有很多地方不懂，继续努力。
