我正在尝试在 OSGi (Equinox) 环境中使用 Hibernate/Spring。如果我明确地将它指向 Persistence.xml 中的实体类,它会很好用:
<class>com.es.t.eee.domain.StuffSource</class>
<class>com.es.t.eee.domain.PostalAddress</class>
我想要的是让 Hibernate 像在 OSGi 环境之外那样“找到”所有实体类。
Hibernate 正在寻找 @Entities 的正确包:
Searching mapped entities in jar/par: bundleresource://34/
WARN 27-07 15:30:24,235 (InputStreamZippedJarVisitor.java:doProcessElements:41):
Unable to find file (ignored): bundleresource://34/
看起来它应该可以工作,但是当它在 Bundle Jar 中查找 @Entities 时,会发生异常,我不知道为什么。我已经包含了 Hibernate 吐出的日志的重要部分。
有谁知道我做错了什么或这里的问题是什么?
我在用:
- 休眠核心 3.3.0.SP1
- 休眠注释 3.4.0.GA
- Hibernate Commons 注释 3.1.0.GA
- 休眠实体管理器 3.4.0.GA
- 春分 3.4
- Spring 动态模块 1.2.0
这是 Hibernate 解析 Persistence.xml 的地方
