1、重慶達渝仁科技官網(wǎng)：www.cqdyr.comJackson框架Jackson可以輕松的將Java對象轉(zhuǎn)換成json對象和xml文檔，同樣也可以將json、xml轉(zhuǎn)換成Java對象。相比json-lib框架，Jackson所依賴的jar包較少，簡單易用并且性能也要相對高些。而且Jackson社區(qū)相對比較活躍，更新速度也比較快。建議：JSON的轉(zhuǎn)換使用Jackson框架；xml的轉(zhuǎn)換使用xStream框架。1.準備工作1.1.下載依賴庫jar包Jackson的jarall下載地址：http://jackson.codehaus.org/1.7.6/jackson-all-1.7.6.
2、jar然后在工程中導入這個jar包即可開始工作官方示例：http://wiki.fasterxml.com/JacksonInFiveMinutes因為下面的程序是用junit測試用例運行的，所以還得添加junit的jar包。版本是junit-4.2.8如果你需要轉(zhuǎn)換xml，那么還需要stax2-api.jar1.2.所需要的JavaEntityBirthday：[java]viewplaincopyprint?1.publicclassBirthday{2.3.privateStringbirthday;4.5.publicBirthday(){6.}7.8.publicBirt
