java 休眠注释编译错误

hibernate annotations compile error

提问by othman

I'm encountering a strange problem when i try to compile a DTO file which has hibernate annotations to map to db . when fails with a strange message log below. what could be the cause of this problem? i suppose the error comes from file CashDTO . what am i doing wrong in file CashDTO.java?

当我尝试编译具有休眠注释以映射到 db 的 DTO 文件时，我遇到了一个奇怪的问题。当失败并显示下面的奇怪消息日志时。这个问题的原因是什么？我想错误来自文件 CashDTO 。我在文件 CashDTO.java 中做错了什么？

Sounds like the classes for javax.persistenceare not on the classpath of the javactask in your test-wsAnt target.

听起来像 for 的类javax.persistence不在javac您的test-wsAnt 目标中的任务的类路径上。
