1、一、正向工程MyEclipse使用hibernate正向工程，hibernate的正向工程是指從java實(shí)體類生成數(shù)據(jù)庫表的過程，這種過程符合java程序員面向?qū)ο缶幊痰乃枷?，也是工程設(shè)計(jì)的時(shí)候使用比較多的一種思想。具體實(shí)施過程如下。①手動(dòng)創(chuàng)建POJO類，并對(duì)POJO類加上Hibernate注解（hibernateannotation）。這樣做的目的是通過MyEclipse來生成hibernate映射文件，POJO類如下（省略set方法）：②配置MyEclipsexdoclet：具體配置方法為，項(xiàng)目選中右擊點(diǎn)properties如下圖操作：locatedintheTomb,DongSh
2、enJiabang,deferthenextdayfocusedontheassassination.Linping,Zhejiang,1ofwhichliquorwinemasters(WuzhensaidinformationisCarpenter),whogotAfewbayonets,duetomissedfatal,whennightcame③選中當(dāng)前項(xiàng)目名稱右擊MyEclipse點(diǎn)擊RunXDoclet:④生成的映射文件：locatedintheTomb,DongShenJiabang,deferthenextdayfocusedontheassassination.Lin
3、ping,Zhejiang,1ofwhichliquorwinemasters(WuzhensaidinformationisCarpenter),whogotAfewbayonets,duetomissedfatal,whennightcame二,逆向工程由數(shù)據(jù)庫表生成javapojo和hibernate映射文件①創(chuàng)建數(shù)據(jù)庫數(shù)據(jù)表：②配置數(shù)據(jù)庫：點(diǎn)擊Window-->showview-->other，選擇MyEclipseEnterpriseWorkBench分支下的DBBrowser，如下圖所示：在DBBrowser窗口中右鍵單擊空白處選擇“New”...，彈出如下窗口進(jìn)行數(shù)據(jù)庫配
4、置（和hibernate.cfg.xml）一樣：配置完成之后出現(xiàn)如下連接：locatedintheTomb,DongShenJiabang,deferthenextdayfocusedontheassassination.Linping,Zhejiang,1ofwhichliquorwinemasters(WuzhensaidinformationisCarpenter),whogotAfewbayonets,duetomissedfatal,whennightcame④創(chuàng)建項(xiàng)目，添加Hibernate支持(略)⑤通過反向工程，生成POJO及hbm映射文件：在DBBrowser配置界面
5、，找到test數(shù)據(jù)庫，展開到表，如下圖所示：選中tb_user點(diǎn)擊右鍵，選擇HibernateReverseEngineering，如下圖所示：將彈出如下的對(duì)話框：locatedintheTomb,DongShenJiabang,deferthenextdayfocusedontheassassination.Linping,Zhejiang,1ofwhichliquorwinemasters(WuzhensaidinformationisCarpenter),whogotAfewbayonets,duetomissedfatal,whennightcame點(diǎn)擊Next>按鈕，在新的對(duì)
6、話框當(dāng)中，在IDGenerator的選項(xiàng)當(dāng)中選擇increment，表示ID為數(shù)據(jù)庫自增長:點(diǎn)擊Next>，可以修改類名或列名:最后，點(diǎn)擊Finish按鈕，新的目錄結(jié)構(gòu)如下圖所示：locatedintheTomb,DongShenJiabang,deferthenextdayfocusedontheassassination.Linping,Zhejiang,1ofwhichliquorwinemasters(WuzhensaidinformationisCarpenter),whogotAfewbayonets,duetomissedfatal,whennightcame
