java 映射出错，找了一年了BUG了

[千百元]

出错内容：


org.springframework.orm.hibernate3.HibernateSystemException: Unknown entity: com.thit.oa.bean.ProjProcess; nested exception is org.hibernate.MappingException: Unknown entity: com.thit.oa.bean.ProjProcess


网上找了很多，什么类名呀都有比对过。 最纠结的是这是新加的项目内容容管理业务，之前的都可以的。。 肯定是那里有小问题，请大家帮看看。

太神奇了，Hibernate用注解都很多年了，竟然还有人在用xml配置

[lvzg_005]

从提供的信息看，应该是配置文件加载的问题，仔细看映射文件被加载的代码是不是被别人修改过，或者说加载的映射配置文件不是你写的这个，而是隐藏在别的位置了。

可以连到数据库的，其他功能可以用。

clear一下 重新在服务器上部署一下工程试试 感觉不像是代码问题

[七神之光]

下载hibernate源码 把引用jar包干掉，然后断点跟踪。。。。如此即可找到异常处，需慎用。。。

java的那种代码+XML配置文件的做法爽吗，跳来跳去的，眼花...

注解可读性不高，而且显得代码混乱。主要还是看公司的开发习惯。 楼主把项目重新编译一下。

这是新增出的错： 当查询时用： return getHibernateTemplate().find("from com.thit.oa.bean.ProjProcess as s where s.userInfo.userId="+userInfo.getUserId()+" order by s.createTime desc"); com.thit.oa.bean.ProjProcess 写完整没出这个错。 新增方法： public void insert(ProjProcess projProcess) throws Exception { System.out.println(projProcess.getBusinessName()+" "+projProcess.getCustomName()); getHibernateTemplate().save(projProcess); } 到这句时：就说找不到实体类了。

既然项目启动加载的时候没有把ProjProcess类成功加载 那么 首先还是考虑hibernate映射的问题；和没有出问题的项目的映射配置对比下，你的配置和我之前写过的有一些差异； 另外 别的工程中是否有引用到过这个实体类，或者别的工程是否有同名的类？ 看下新增方法中的ProjProcess类的引用是否正确。
