hibernate_Eclipse+hibernate+mysql配置

原工做環境是myecilpse，考慮到myeclipse愈來愈冗餘，且myeclipse集成度高，封裝了較多操做，不少細節都是傻瓜式配置，不便於成長，依賴度過高，遂工做平臺從myeclipse轉到eclipse下。

工具：

eclipse

hibernate eclipse tool

hibernate orm

mysql jdbc driver

slf4j

log4j

下載各工具後，hibernate eclipse壓縮包放到eclipse dropin目錄下解壓縮，啓動eclipse.

1，建立java project test，hibernate orm下載解壓後，hibernate3.jar以及lib目錄下requeire目錄下jar包導入工程；把mysql jdbc driver jar包導入工程，

2，配置hibernate映射文件:hibernate.cfg.xml

     到hibernate-distribution-3.5.0-Final\project\tutorials\web\src\main\resources目錄下把hibernate配置文件拷貝到test/src目錄下,根據具體狀況修改配置文件,配置見文尾附錄;

3，建立映射文件，映射類: Event.hbm.xml,Event類

    test工程下建立包:com.xinju.hibernate,包下建立配置文件 Event.hbm.xml,映射類:,代碼見附錄

4，運行測試類。

或者是報錯：

Initial SessionFactory creation failed.java.lang.NoClassDefFoundError: org/apache/log4j/Level

運行報錯，緣由在於hibernate require包不包含slf4j引用包，需下載slf4j包，包的版本根據slf4j-api.1.5.8.jar，下載slf4j1.5.8,解壓slf4j-log4j12-1.5.8.jar以及log4j-1.2.17.jar

這一部分官方文檔3.5節日誌部分有詳細描述。
