怎样进行SpringBoot基于数据库的定时任务统一管理的实现

这篇文章给大家介绍怎样进行SpringBoot基于数据库的定时任务统一管理的实现，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。

定时任务1

import lombok.extern.slf4j.Slf4j;/** * @author Created by niugang on 2019/12/24/15:29 */@Slf4jpublic class TaskTest { public void task1() { log.info("反射调用测试[一]类"); }}

定时任务2

import lombok.extern.slf4j.Slf4j;/** * @author Created by niugang on 2019/12/24/15:54 */@Slf4jpublic class TaskTest2 { public void task2() { log.info("反射调用测试[二]类"); }}

配置类

import lombok.Data;import lombok.extern.slf4j.Slf4j;import org.springframework.context.annotation.Configuration;import org.springframework.scheduling.annotation.EnableScheduling;import org.springframework.scheduling.annotation.SchedulingConfigurer;import org.springframework.scheduling.config.CronTask;import org.springframework.scheduling.config.ScheduledTask;import org.springframework.scheduling.config.ScheduledTaskRegistrar;import java.lang.reflect.Method;import java.util.ArrayList;import java.util.List;/** * @author Created by niugang on 2019/12/24/15:19 */@Configuration@EnableScheduling@Slf4jpublic class CompleteScheduleConfig implements SchedulingConfigurer { private static List taskRecordList = new ArrayList<>();

/* *模拟数据库存储 */ static {

TaskRecord taskRecord = new TaskRecord(); taskRecord.setExecuteMehod("task1");

taskRecord.setClassPath("com.example.demo.pojo.TaskTest");

taskRecord.setCron("0/5 * * * * ?");

taskRecordList.add(taskRecord);

TaskRecord taskRecord2 = new TaskRecord();

taskRecord2.setExecuteMehod("task2");

taskRecord2.setClassPath("com.example.demo.pojo.TaskTest2");

taskRecord2.setCron("0/10 * * * * ?");

taskRecordList.add(taskRecord2); } @Override public void configureTasks(ScheduledTaskRegistrar taskRegistrar) { // taskRegistrar.addCronTask(() -> log.info("执行定时任务,{}", LocalDateTime.now()), "0/5 * * * * ?");/* taskRegistrar.addCronTask(new Runnable() {

@Override public void run() { try {

Class aClass = Class.forName("com.example.demo.pojo.TaskTest");

Object o = aClass.newInstance();

Method[] declaredMethods = aClass.getDeclaredMethods(); for (Method declaredMethod : declaredMethods) { declaredMethod.invoke(o);

// log.info("方法名称:{}",declaredMethod.getName());

} }

catch (Exception e) { e.printStackTrace();

} } }, "0/5 * * * * ?");

*/ for (TaskRecord taskRecord : taskRecordList) { String classPath = taskRecord.getClassPath();

String cron = taskRecord.getCron();

String executeMehod = taskRecord.getExecuteMehod();

Runnable runnable = () -> { Class aClass;

try { aClass = Class.forName(classPath);

Object o = aClass.newInstance();

Method[] declaredMethods = aClass.getDeclaredMethods();

for (Method declaredMethod : declaredMethods) {

if (declaredMethod.getName().equals(executeMehod)) {

/// log.info("方法名称:{}",declaredMethod.getName());

declaredMethod.invoke(o);

} } }

catch (Exception e1) { e1.printStackTrace();

} };

CronTask cronTask = new CronTask(runnable, cron);

ScheduledTask scheduledTask = taskRegistrar.scheduleCronTask(cronTask);

//scheduledTask.cancel(); 取消定时任务 } }

@Data private static class TaskRecord { private String classPath;

private String executeMehod;

private String cron;

//可以在增加一个type 执行其他类型的定时任务 }}
