Hibernate配置過程可能發生的問題及解決方法

1.問題：Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentException

at HibernateTest.main(HibernateTest.java:14)

方法：添加dom4j.jar(解析hibernate.cfg.xml文件)

2．問題：Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

at org.hibernate.cfg.Configuration.<clinit>(Configuration.java:116)

at HibernateTest.main(HibernateTest.java:14)

方法：添加commons-logging.jar(記錄解析過程)

3．問題：Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/collections/SequencedHashMap

方法：添加commons-collections.jar(在解析映射文件時，需要把所有持久化對象的定義放在一個HashMap中)

4．問題：Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/ehcache/CacheException

方法：添加ehcache.jar(高速緩存，提高存取速度)

5．問題：2009-2-22 23:45:40 net.sf.ehcache.config.Configurator configure

警告: No configuration found. Configuring ehcache from ehcache-failsafe.xml found in the classpath: jar:file:/F:/MyJava/Hibernate/lib/ehcache-1.1.jar!/ehcache-failsafe.xml

Exception in thread "main" java.lang.NoClassDefFoundError

方法：把ehcache-1.1.jar解壓，把其中的ehcache-failsafe.xml改成ehcache.xml。

6.問題：Caused by: java.lang.ClassNotFoundException: net.sf.cglib.transform.impl.InterceptFieldEnabled
