软件版本:
hibernate-3.2.0.cr2
hibernate-annotations-3.2.0.CR1

IDE:
idea 5.1

以前都是用XDoclet来实现类似Annotation的功能,但是xdoclet的版本更新实在太慢,永远跟不上hibernate的更新速度,导致很多hibernate新的功能xdoclet都没办法支持.还好,jdk5.0有了Annotation,而且hibernate也开始支持Annotation了.

原来以为从xdoclet转到Annotation很简单,没想到还是遇到了问题,先看代码:

看上去没什么问题吧?没想到运行的时候根本跑不起来,老是提示:

看了半天看不出有什么问题,最后终于参考hibernate-annotations-3.2.0.CR1里面单元测试的代码才发现是这段代码有问题:

1解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEAimport org.hibernate.annotations.Entity;
2解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEA
3解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEAimport javax.persistence.Id;
4解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEAimport java.io.Serializable;
5解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEA


要改成:

1解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEAimport javax.persistence.Id;
2解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEAimport javax.persistence.Entity;
3解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEAimport java.io.Serializable;


原来我用idea开发时,在自动完成的时候想当然地选用了org.hibernate.annotations包下面的annotation,而实际上应该使用javax.persistence包下面的annotation.想想看也很有道理:这样一来我们的JAVA bean就不用import hibernate的包了,用的都是标准的java包.解决 Hibernate Annotation 的 "no persistent classes found for query class" 问题 HibernateJavaAntApacheIDEA
