Spring整合Quartz （cronTrigger和simpleTrigger实现方法）

之前有记录过一次springboot整合Quartz的文章，由于偶尔一次自己使用spring需要整合Quartz时有遇到一些异常，导致定时job无法正常执行，所以在此也记录一下spring整合quartz的两种实现方式。SpringBoot整合Quartz

应用框架版本

Spring 5.1.4.RELEASE
Quartz 2.3.0
Maven 3.5.0

pom.xml依赖

在使用quartz版本时需要注意与spring的版本对应。
spring 3.0版本内置的是Quartz<2.0的版本，所以在使用Spring 3.0版本以上时，需要使用Quartz 2.0以上的版本

TimerTask.java

package com.test.quartz.timer;

import com.test.quartz.service.TaskService;

/**
 * @author yd
 * @date 2019-06-11 16:08
 * @describe 定时job1
 */
public class TimerTask {

    private TaskService taskService;

    public TaskService getTaskService() {
        return taskService;
    }

    public void setTaskService(TaskService taskService) {
        this.taskService = taskService;
    }

    public void run(){
        String process = taskService.process(this.getClass().getSimpleName());
        System.out.println(process);
    }

}

TimeTask2.java

package com.test.quartz.timer;

import com.test.quartz.service.TaskService;

/**
 * @author yd
 * @date 2019-06-11 16:28
 * @describe 定时job2
 */
public class TimeTask2 {

    private TaskService taskService;

    public TaskService getTaskService() {
        return taskService;
    }

    public void setTaskService(TaskService taskService) {
        this.taskService = taskService;
    }

    public void run(){
        String process = taskService.process(this.getClass().getSimpleName());
        System.out.println(process);
    }
}

service

在对quartz集成的同时，在这里也引入了service层的注入，demo中只是一个简单的样例，可以根据自己的实际需求去对service层进行编辑。

TaskService.java

package com.test.quartz.service;

import org.springframework.stereotype.Service;

/**
 * @author yd
 * @date 2019-06-11 16:11
 * @describe 文件描述
 */

@Service
public class TaskService {

    public String process(String taskname){
        return this.getClass().getSimpleName()+"在处理任务："+taskname;
    }
}

执行结果
