osgi spring hibernate virgo 示例 ClassNotFoundException: org.hibernate.cfg.Configuration

Question

我正在尝试构建非常简单的应用程序，将数据保存到作为 osgi 包运行的数据库（在 Virgo 下）。 当我尝试通过网络界面将 jar 上传到 virgo 时，出现下一个错误。

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

我不久前开始学习osgi，很可能做错了什么。

Answer 1

最后我解决了问题。我用 springsource 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>

另外，我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>

并将捆绑包加载到处女座，并且可以使用休眠。

Answer 2

您缺少对 hibernate3.jar 文件的引用。该文件位于 Hibernate 3 二进制包的根目录中。

希望有帮助。
