3. 监听器保证项目启动的时候会调用到
/**
* Created with IntelliJ IDEA.
*
* @author: zhangenke
* @Date: 2018-12-19 on 17:29
* @description: 监听器保证项目启动的时候会调用到，我们的定时任务，代码如下：
*/
@Slf4j
@Configuration
public class SchedulerListener implements ApplicationListener<ContextRefreshedEvent> {
@Autowired
private MyScheduler myScheduler;
@Autowired
private JobFactory jobFactory;
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
try {
myScheduler.scheduleJobs();
} catch (SchedulerException e) {
e.printStackTrace();
}
}
/**
* 配置SchedulerFactoryBean
* 将一个方法产生为Bean并交给Spring容器管理
*/
@Bean
public SchedulerFactoryBean schedulerFactoryBean() {
// Spring提供SchedulerFactoryBean为Scheduler提供配置信息,并被Spring容器管理其生命周期
SchedulerFactoryBean factory = new SchedulerFactoryBean();
// 设置自定义Job Factory，用于Spring管理Job bean
factory.setJobFactory(jobFactory);
return factory;
}
}
4. 解决Springboot在Quartz中注入Bean的问题
package com.construn.procure.quartz;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.stereotype.Component;
/**
* Created with IntelliJ IDEA.
*
* @author: zhangenke @Date: 2018-12-26 on 15:56
* @description: 解决SpringBoot不能再Quartz中注入Bean的问题
*/
@Component
public class JobFactory extends org.springframework.scheduling.quartz.SpringBeanJobFactory {
/** AutowireCapableBeanFactory接口是BeanFactory的子类 可以连接和填充那些生命周期不被Spring管理的已存在的bean实例 */
@Autowired
private AutowireCapableBeanFactory beanFactory;
/** 创建Job实例 */
@Override
protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
// 实例化对象
Object job = super.createJobInstance(bundle);
// 进行注入（Spring管理该Bean）
beanFactory.autowireBean(job);
// 返回对象
return job;
}
}
5. 其中一个自动过期类
/**
* Created with IntelliJ IDEA.
*
* @author: zhangenke @Date: 2018-12-20 on 10:21
* @description: 订单下单审核自动过期任务
* @description: 01-21 遇到Job初始化错误，原因是，Job类必须要有默认的无参构造方法！！！
*/
@Slf4j
@Component
public class BidExpiredJob implements Job {
private SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
@Autowired private SupplierDao supplierDaoImpl;
@Autowired private UserClient userClient;
public BidExpiredJob() {}
@Override
public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
log.info("订单过期任务开始执行：{}", simpleDateFormat.format(new Date()));
try {
log.info("标书正在关闭啊 ～～～～～～");
userClient.updateBidStatusByExpired(jobExecutionContext.getJobDetail().getKey().getName());
int count =
supplierDaoImpl.updateBidStatusByExpired(
jobExecutionContext.getJobDetail().getKey().getName());
if (count != 1) {
log.info("此标书状态已不是开标状态，已被关标，故不自动更新");
} else {
log.info("已自动过期：{}条", count);
}
log.info(
"删除任务：{}，必须是true,否则遇到了严重的错误",
jobExecutionContext
.getScheduler()
.deleteJob(jobExecutionContext.getJobDetail().getKey()));
} catch (Exception e) {
log.error("订单过期任务出错,{}", e);
}
}
}
6. 时间表达式工具类
/**
* Created with IntelliJ IDEA.
*
* @author: zhangenke
* @Date: 2018-12-26 on 11:52
* @description: 获取定时任务，时间表达式
*/
@Component
@Slf4j
public class GetCronUtils {
private static final String SPACE = " ";
private static SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
/**
* 获取时间表达式，
*
* @param date 创建时间
* @param expiredValue 过期值（单位秒）
* @return
*/
public String getCron(Date date, int expiredValue) {
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
calendar.add(Calendar.SECOND, expiredValue);
return cron(calendar);
}
public String getNowRandomCron() {
Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.MINUTE, new Random().nextInt(9) + 1);
return cron(calendar);
}
/**
* 如果他的时间加上五天，比现在的时间大，说明，已经过期，需要立刻执行过期逻辑
*
* @param oldDate
* @param expiredValue 过期值
* @return
*/
public boolean compareTime(Date oldDate, int expiredValue) {
Calendar calendar = Calendar.getInstance();
calendar.setTime(oldDate);
calendar.add(Calendar.SECOND, expiredValue);
log.info("任务时间 + {}天：{},现在时间：{}", expiredValue, simpleDateFormat.format(calendar.getTime()),
simpleDateFormat.format(new Date()));
if (calendar.getTime().getTime() < System.currentTimeMillis()) {
log.info("任务时间 + {}天还是小与当前时间，所以已经严重超时，现在随机执行过期任务", expiredValue);
return true;
}
return false;
}
private String cron(Calendar calendar) {
int year = calendar.get(Calendar.YEAR);
String month = (calendar.get(Calendar.MONTH) + 1) + "";
int day = calendar.get(Calendar.DAY_OF_MONTH);
int hour = calendar.get(Calendar.HOUR_OF_DAY);
int minute = calendar.get(Calendar.MINUTE);
int second = calendar.get(Calendar.SECOND);
log.info("年，月，日，时，分，秒:{}-{}-{} {}:{}:{}", year, month, day, hour, minute, second);
return second + SPACE + minute + "/1" + SPACE + hour +
SPACE + day + SPACE + month + SPACE + "?" + SPACE + "*";
}
}
7. 总结：
1. 首先要明确需求，再决定技术选型；
2. 遇到新技术，多打开几个博客园、CSDN博客等Demo，然后自己调试；
3. 遇到问题，再进行google解决。有很多问题前辈们都已经解决，你只需要找到而已；
4. 菜鸟分享，大佬勿喷；
5. @Autowired此注解，不能随便注入到构造函数类，否则会出现问题；
6. 所有出现的问题，我已经解决并且加了注释，都能看懂；
