Quartz調度框架定時發送郵箱

Quartz調度框架定時發送郵箱

百度百科
Quartz是OpenSymphony開源組織在Job scheduling領域又一個開源項目，它可以與J2EE與J2SE應用程序相結合也可以單獨使用,Quartz是一個完全由java編寫的開源作業調度框架,這個過程需要我們不斷的測試和學習

核心組件
1.Job–>JobDetail描述Job，任務的名稱、所屬組其他靜態信息
2、觸發器Trigger：簡單的時間觸發器（simpletrigger）、複雜的時間觸發器（crontrigger）已固定的時間間隔、固定的執行次數
3、調度器scheduler：負責調配觸發器和任務（哪一個觸發器—>哪一個任務）
