Quartz是一個(gè)開源的作業(yè)調(diào)度框架，它完全由Java寫成，并設(shè)計(jì)用于J2SE和J2EE應(yīng)用中。下面介紹在J2SE中應(yīng)用的郵件發(fā)送工作調(diào)度程序.
?????????? Quartz要運(yùn)行起來,最簡單需要1. ***Job? 自己實(shí)現(xiàn)的工作類 ;2. ***Quartz 調(diào)度你實(shí)現(xiàn)的工作類.
?????????? 一.? ***Job.java 實(shí)現(xiàn)Quartz框架的Job接口.

??????????????? 上面這個(gè)郵件發(fā)送程序非常實(shí)用,很多系統(tǒng)都應(yīng)該可以用到,要應(yīng)用于WEB應(yīng)用需要改動(dòng)的地方也不多.希望大家試試改造一番,用于自己的網(wǎng)站,不過很多網(wǎng)站已經(jīng)有這樣的應(yīng)用了,哈哈!
