Quartz+Spring Boot實(shí)現(xiàn)動(dòng)態(tài)管理定時(shí)任務(wù)
更新時(shí)間：2018年09月10日 09:39:49 作者：黑米面包派
最近做項(xiàng)目遇到動(dòng)態(tài)管理定時(shí)任務(wù)的需求，剛拿到這個(gè)需求還真不知道從哪下手，經(jīng)過(guò)一番思考，終于找出實(shí)現(xiàn)思路，接下來(lái)通過(guò)本文給大家介紹了Quartz+Spring Boot實(shí)現(xiàn)動(dòng)態(tài)管理定時(shí)任務(wù)的相關(guān)知識(shí),需要的朋友可以參考下
項(xiàng)目實(shí)踐過(guò)程中碰到一個(gè)動(dòng)態(tài)管理定時(shí)任務(wù)的需求：針對(duì)每個(gè)人員進(jìn)行信息的定時(shí)更新，具體更新時(shí)間可隨時(shí)調(diào)整、啟動(dòng)、暫定等。
思路
將每個(gè)人員信息的定時(shí)配置保存到數(shù)據(jù)庫(kù)中，這樣實(shí)現(xiàn)了任務(wù)的動(dòng)態(tài)展示和管理。任務(wù)的每一次新增或變更，都會(huì)去數(shù)據(jù)庫(kù)變更信息。
設(shè)置一個(gè)統(tǒng)一的任務(wù)管理器，專(zhuān)門(mén)負(fù)責(zé)動(dòng)態(tài)任務(wù)的增刪改查。
