spring+hibernate整合时出现的错误

刚接触SSH框架&＃xff0c;学习的过程中一动手就是各种bug&＃xff0c;在此记录一下bug。

Bug1:使用spring4.1.0&＃43;hibernate3.0.5出现如下异常

hibernate的实体类是使用xml文件配置的&＃xff0c;配置如下&＃xff1a;

org.hibernate.cache.RegionFactory org.hibernate.dialect.MySQLDialecttruetrueupdate

网上百度了一大圈&＃xff0c;尝试了一大堆方法&＃xff0c;最终看到一位说是hibernate3.0版本压根就没有这个org.hibernate.cache.RegionFactory类&＃xff0c;因此最后把hibernate3.0.5版本换成3.3.2版本问题就解决了。如果

hibernate某版本的各种包都加载了&＃xff0c;还是报这种没有类的错误很可能是版本的问题。

Bug2&＃xff1a;xml配置实体麻烦&＃xff0c;就想用注解方式配置实体类&＃xff0c;一动手又掉坑里了&＃xff0c;使用spring4.1.0&＃43;hibernate3.3.2&＃xff0c;异常如下&＃xff1a;

org.hibernate.cfg.Configuration.addAnnotatedClass(Ljava/lang/Class;)Lorg/hibernat又百度最终还是版本问题
&＃xff0c;把hibernate最终换4.1.0版本就好了。底子太弱&＃xff0c;一走一个坑&＃xff01;&＃xff01;&＃xff01;
