OpenXava是一個(gè)讓使用XML與Java來(lái)開發(fā)J2EE商業(yè)應(yīng)用程序變得簡(jiǎn)單的框架.OpenXava不使用常見的MVC架構(gòu)，它是一個(gè)JPA應(yīng)用程序引擎，你能夠通過(guò)JDK5.0注解或XML描述對(duì)象-關(guān)系表的映射關(guān)系，并將運(yùn)行期實(shí)體對(duì)象持久化到數(shù)據(jù)庫(kù)中去。

      使用OpenXava你只需要寫model，POJOs，和Java 5 annotations，你不用寫view，也不用寫controller。
