jfinal整合quartz实现定时任务的两种方式
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
第一種實現方式
1.導入包
<dependency>
?? ??? ? ? ?<groupId>org.quartz-scheduler</groupId>
?? ??? ? ? ?<artifactId>quartz</artifactId>
?? ??? ? ? ?<version>2.3.0</version>
?? ??? ?</dependency> |
2：在myconfig中配置quartz插件：
QuartzPlugin quatrZPlugin = new QuartzPlugin();
me.add(quatrZPlugin);//定時任務插件
3.在根目錄下設置配置文件，我設置的目錄是src/main/resources
quartz_config.properties
| #配置主要調度程序屬性 org.quartz.scheduler.instanceName = DefaultQuartzScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false
?
#配置線程池
org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 5
?
#?配置任務
org.quartz.jobStore.misfireThreshold = 60000
org.quartz.scheduler.skipUpdateCheck = true |
?
4.在src/main/java下面編寫代碼
? ? 所需工具類有三個：FormaterCronExpression.java、QuartZKit.java、QuartzPlugin.java；需要一個實體類：JobBean.java；然后就可以編寫任務了，目錄結構如下圖：
（1），config配置類，
（2），任務實體類，
（3），任務實現類，
（4），工具類，
（5）.配置文件。
JobBean.java：
|
public class JobBean {
?? ?/** 任務id */
?? ?private String jobId;
?
?? ?/** 任務描述 */
?? ?private String jobDesc;
?
?? ?/** 任務運行時間表達式 */
?? ?private String cronExpression;
?
?? ?/** 任務分組 */
?? ?private String jobGroup;
?
?? ?/** 任務類 */
?? ?private String jobClass;
?
?? ?public String getJobId() {
?? ??? ?return jobId;
?? ?}
?
?? ?public void setJobId(String jobId) {
?? ??? ?this.jobId = jobId;
?? ?}
?
?? ?public String getJobDesc() {
?? ??? ?return jobDesc;
?? ?}
?
?? ?public void setJobDesc(String jobDesc) {
?? ??? ?this.jobDesc = jobDesc;
?? ?}
?
?? ?public String getCronExpression() {
?? ??? ?return cronExpression;
?? ?}
?
?? ?public void setCronExpression(String cronExpression) {
?? ??? ?this.cronExpression = cronExpression;
?? ?}
?
?? ?public String getJobGroup() {
?? ??? ?return jobGroup;
?? ?}
?
?? ?public void setJobGroup(String jobGroup) {
?? ??? ?this.jobGroup = jobGroup;
?? ?}
?
?? ?public String getJobClass() {
?? ??? ?return jobClass;
?? ?}
?
?? ?public void setJobClass(String jobClass) {
?? ??? ?this.jobClass = jobClass;
?? ?}
?
?? ?public JobBean(String jobId, String jobDesc, String cronExpression, String jobGroup, String jobClass) {
?? ??? ?this.jobId = jobId;
?? ??? ?this.jobDesc = jobDesc;
?? ??? ?this.cronExpression = cronExpression;
?? ??? ?this.jobGroup = jobGroup;
?? ??? ?this.jobClass = jobClass;
?? ?}
?
?? ?public JobBean() {
?? ??? ?super();
?? ?}
}
?
|
FormaterCronExpression.java：
| import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class FormaterCronExpression {
?? ?static String formart = "yyyy-MM-dd HH:mm:ss";
?? ??
?? ?public static String formaterCronExpression(String date){
?? ??? ?SimpleDateFormat format = new SimpleDateFormat(formart.substring(0, date.length() - 1));
?? ??? ?SimpleDateFormat format2 = new SimpleDateFormat("yyyy MM dd HH mm ss");
?? ??? ?try {
?? ??? ??? ?Date d = format.parse(date);
?? ??? ??? ?date = format2.format(d);
?? ??? ??? ?String[] dateArry = date.split(" ");
?? ??? ??? ?String exp = dateArry[5] + " " + dateArry[4] + " " + dateArry[3] + " " + dateArry[2] + " " + dateArry[1]
?? ??? ??? ??? ??? ?+ " ? " + dateArry[0];
?? ??? ??? ?return exp;
?? ??? ?} catch (ParseException e) {
?? ??? ??? ?e.printStackTrace();
?? ??? ?}
?? ??? ?return "";
?? ?}
}
?
|
QuartZKit.java：
| package com.pointlion.sys.plugin.quartz; import com.pointlion.sys.plugin.quartz.bean.JobBean;
public class QuartZKit {
?? ?/***
?? ? * 動態添加任務
?? ? */
?? ?public static void addTask(String taskid , String closeTime){
?? ? ? ?JobBean job = new JobBean();
?? ? ? ?job.setJobClass("com.pointlion.sys.plugin.quartz.task.ResetYearHoliday");
?? ? ? ?job.setCronExpression(FormaterCronExpression.formaterCronExpression(closeTime));
?? ? ? ?job.setJobGroup("DakeTaskJob");
?? ? ? ?job.setJobDesc("DakeTaskJob_" + taskid);
?? ? ? ?QuartzPlugin.addJob(job);
?? ?}
}
?

QuartzPlugin.java：

任務示例ResetYearHoliday
| package com.pointlion.sys.plugin.quartz.task; import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory; import com.jfinal.kit.PropKit;
import com.jfinal.plugin.activerecord.Db;
public class ResetYearHoliday implements Job{
?? ?private static final Logger logger = LoggerFactory.getLogger(ResetYearHoliday.class); ?
?? ?@Override
?? ?public void execute(JobExecutionContext context) {
?? ??? ?logger.info("*****************************開始重置所有員工年假******************");
?? ??? ?Db.update("update sys_user set year_holiday = '"+PropKit.get("yearHoliday").trim()+"' where type='1'");
?? ??? ?logger.info("*****************************完成重置所有員工年假******************");
?? ?}
}
? |
第一種定時任務實現代碼編寫結束，啟動項目即可運行。
?
第二種實現方式
?? ? ?前兩步和第一種實現方式一致，第三步中除了需要配置quartz_config.properties，配置內容和第一種方式中相同名字的配置文件內容一致；還需要配置quartz_job.properties，配置內容如下。
quartz_job.properties
| #配置第一個定時任務 #開啟的任務列表“,”隔開 實際上為group
#jobArray = CrawlDataPolicyTask
jobArray =CheckTimeTask
#搭客任務定時結束
#[秒] [分] [小時] [日] [月] [周] [年]
CheckTimeTask.class=com.pointlion.sys.plugin.quartz.task.CheckTimeTask
CheckTimeTask.group=CheckTimeTask
CheckTimeTask.cron=0 0 1 * * ?
CheckTimeTask.desc=\u6BCF\u5E74\u91CD\u7F6E\u5E74\u5047\u6570\u91CF ? #配置第二個定時任務 jobArray =DemoTask
DemoTask.class=com.pointlion.sys.plugin.quartz.task.DemoTask
DemoTask.group=DemoTask
DemoTask.cron=0/10 * * * * ??
DemoTask.desc=\u6BCF\u5E74\u91CD\u7F6E\u5E74\u5047\u6570\u91CF |
第四步所需要的工具類QuartzPlugin.java和實體類JobBean.java和第一種實現方式中的一致。
第五步，編寫定時任務內容，如下：
任務實例：DemoTask：
|
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class DemoTask implements Job { ?? ?@Override
?? ?public void execute(JobExecutionContext arg0) throws JobExecutionException {
?? ??? ?System.out.println("##########開始定時任務##########");
?? ??? ?System.out.println("aaaaaaaaaaaaaa");
?? ??? ?System.out.println("##########結束定時任務##########");
?? ? ? ?
?? ?}
?? ?
} |
?第二種定時任務代碼編寫結束，啟動項目即可運行。
