【中文标题】osgi spring hibernate virgo example ClassNotFoundException: org.hibernate.cfg.Configuration【英文标题】： 【发布时间】：2011-06-26 14:28:46 【问题描述】：

我正在尝试构建一个非常简单的应用程序，将数据保存到 DB 作为 osgi 包运行（在 Virgo 下）。当我尝试通过 web 界面将 jar 上传到处女座时，出现下一个错误。

我使用命令创建包：“mvn clean install org.apache.felix:maven-bundle-plugin:bundle”，还将所有项目依赖项 jar 放到服务器 /repository/usr/ 目录中。

我不久前开始学习 osgi，而且很可能做错了什么。

【问题讨论】：

【参考方案1】：

最后我解决了问题。我用 springsource 中的 osgi-ready 替换了 hibernate 和 mysql 库。

    <dependency>
        <groupId>com.mysql.jdbc</groupId>
        <artifactId>com.springsource.com.mysql.jdbc</artifactId>
        <version>5.1.6</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>com.springsource.org.hibernate</artifactId>
        <version>3.3.2.GA</version>
    </dependency>

我还将构建指令部分更改为（因此创建了正确的清单）：

  <instructions>
    <Bundle-SymbolicName>$project.artifactId</Bundle-SymbolicName>
    <Bundle-Name>$bundle.name</Bundle-Name>
    <Bundle-Version>$pom.version</Bundle-Version>
    <Export-Package>$project.artifactId.*</Export-Package>
    <Import-Bundle>com.springsource.org.hibernate</Import-Bundle>
  </instructions>

并且捆绑加载到处女座，并且可以使用休眠。

【参考方案2】：

您以某种方式缺少对 hibernate3.jar 文件的引用。该文件位于 Hibernate 3 二进制包的根目录中。

希望对你有帮助。

【讨论】：

很抱歉撤销接受，因为我发现并发布了更好的解决方案。但是你的建议让我走上了正轨，谢谢！
