hibernate3升级hiberante4方法

怎么升级hibernate3 到hibernate4 及遇到的问题
1. 将原有hibernate3 jar全部删掉
2. 建议去网上下载完整的hibernate4.8 的jar,然后全部贴进去(不建议单独升级对应的jar，因为高版本可能会分拆低版本的jar，或者添加了依赖包)




3.遇到的错误
3.1
2016-03-01 04:34:24.072::WARN:  Failed startup of context org.mortbay.jetty.webapp.WebAppContext@bafda6{/naiu,src/main/webapp}
2. org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0' defined in file [E:\eclipse\workspace\NAIU\src\main\webapp\WEB-INF\classes\beans\dataAccessContext-jpa-local.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in file [E:\eclipse\workspace\NAIU\src\main\webapp\WEB-INF\classes\beans\dataAccessContext-jpa-local.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Error loading class [org.hibernate.ejb.HibernatePersistence]: problem with class file or dependent class.
解决办法：升级本地jdk1.5 为jdk1.6




3.2
1. Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0' defined in file [E:\eclipse\workspace\NAIU\src\main\webapp\WEB-INF\classes\beans\dataAccessContext-jpa-local.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in file [E:\eclipse\workspace\NAIU\src\main\webapp\WEB-INF\classes\beans\dataAccessContext-jpa-local.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getSharedCacheMode()Ljavax/persistence/SharedCacheMode;
解决办法：删除  ejb3-persistence-3.0(我的项目使用的是jpa，已经添加了hibernate-jpa)

升级jar为 javassist-3.15.0-GA.jar 原先的为3.0

解决办法：好像是 sql语句中，出现了相同的列名，给相同的列名起别名








3.5
org.springframework.orm.jpa.JpaSystemException: org.hibernate.MappingException: No Dialect mapping for JDBC type: -9; nested exception is javax.persistence.PersistenceException: org.hibernate.MappingException: No Dialect mapping for JDBC type: -9


经验证 weblogic9(正常)和weblogic10(不正常) 版本不同 出现的问题.
解决办法： 1.新建类oracledialect  同时改jdbc.properties
将原有hibernate.dialect=org.hibernate.dialect.OracleDialect
改为hibernate.dialect=com.cpic.naiu.cpic.util.OracleDialect


import org.hibernate.dialect.Oracle10gDialect;


public class OracleDialect  extends Oracle10gDialect{


public OracleDialect() {
super();
  registerHibernateType(1, "string");  
       registerHibernateType(-9, "string");  
       registerHibernateType(-16, "string");  
       registerHibernateType(3, "double");  
}

解决办法： 给文件夹 附上写入权限
