直播系统开发，springboot指定时间触发定时任务
新建测试Demo类执行定时任务
package com.task.zhixingshijian;
import java.time.LocalDateTime;
import java.time.temporal.ChronoField;
import java.util.*;
/**
* @author wuzhenyong
* ClassName:TaskDemo.java
* date:2022-09-28 09:44
* Description:
*/
public class TaskDemo {
/**
* 指定时间执行一次定时任务
*
* @param localDateTime 触发时机
* @param timing 参数信息
*/
public void timing(LocalDateTime localDateTime, Map<String, String> timing) {
Calendar calendar = Calendar.getInstance();
// 年份
calendar.set(Calendar.YEAR, localDateTime.get(ChronoField.YEAR));
// 月份 传入日期需要-1
calendar.set(Calendar.MONTH, localDateTime.get(ChronoField.MONTH_OF_YEAR)-1);
// 天数
calendar.set(Calendar.DAY_OF_MONTH, localDateTime.get(ChronoField.DAY_OF_MONTH));
// 小时
calendar.set(Calendar.HOUR_OF_DAY, localDateTime.get(ChronoField.HOUR_OF_DAY));
// 分钟
calendar.set(Calendar.MINUTE, localDateTime.get(ChronoField.MINUTE_OF_HOUR));
// 秒
calendar.set(Calendar.SECOND, localDateTime.get(ChronoField.SECOND_OF_MINUTE));
Date time = calendar.getTime();
Timer timer = new Timer();
// 执行
timer.schedule(new TimerTask() {
@Override
public void run() {
System.out.println("执行了指定执行时间任务，localDateTime:" + LocalDateTime.now());
System.out.println("执行内容：" + timing.toString());
}
}, time);
}
}
创建项目启动后进行配置具体时间执行定时类
注意：此类只是测试一下，如果项目中是不需要此类的
package com.task.zhixingshijian;
import org.springframework.stereotype.Component;
import java.time.LocalDateTime;
import java.util.HashMap;
import java.util.Map;
/**
* @author wuzhenyong
* ClassName:TaskCommandLineRunner.java
* date:2022-09-28 09:43
* Description:
*/
@Component
public class TaskCommandLineRunner implements org.springframework.boot.CommandLineRunner {
/**
* 启动项目后运行
*
* @param args arg游
*/
@Override
public void run(String... args) {
// 指定触发的时间1
LocalDateTime localDateTime1 = LocalDateTime.of(2022, 9, 28, 10, 14, 00);
Map<String, String> timing1 = new HashMap<>();
timing1.put("name", "timing1");
new TaskDemo().timing(localDateTime1, timing1);
// 指定触发的时间2
LocalDateTime localDateTime2 = LocalDateTime.of(2022, 9, 28, 10, 13, 00);
Map<String, String> timing2 = new HashMap<>();
timing2.put("name", "timing2");
new TaskDemo().timing(localDateTime2, timing2);
// 指定触发的时间3
LocalDateTime localDateTime3 = LocalDateTime.of(2022, 9, 28, 10, 15, 00);
Map<String, String> timing3 = new HashMap<>();
timing3.put("name", "timing3");
new TaskDemo().timing(localDateTime3, timing3);
}
}
