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

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

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
