獲取javaBean所有屬性及類(lèi)型

1、獲得javaBean的所有屬性及類(lèi)型一、程序功能定義a) 獲得javabean所有屬性及類(lèi)型b) 僅僅是獲得，賦值還沒(méi)想到怎么弄。二、目的a) 參考方法b) 目前還不知道有什么用。c) 本來(lái)想給javaBean 一次性賦值的，但是貌似吧得用反射才行，而反射挺費(fèi)資源的, 那只好暫時(shí)擱一擱了。三、程序代碼四、代碼中公用到兩個(gè)類(lèi)a) getBea ns.java 與 pers on Bea n.java getBea ns.javaimportjava.bea ns.Bea nlnfo;importjava.bea ns.ln trospect ion Exceptio n;importjava.b
