Java 使用OSGI将H2数据库添加到Jetty-无法解析驱动程序

我将独立Jetty与org.eclipse.Jetty.osgi.boot捆绑包一起用于我的webapp。 到目前为止，一切都很令人满意。但现在我尝试使用身份验证并添加一个JDBS数据源来存储我的用户凭据

为此，我在jetty.xml中添加了以下代码（根据jetty文档）：

---

Jetty boot使用其包的类加载器来解析配置中的任何类。为了让Jetty看到H2的包装，我可以想到一个选项：

创建一个bundle，它是jetty引导的片段，并导入必要的H2包。您的捆绑包将只有一个MANIFEST.MF文件，其内容如下：

Bundle-SymbolicName: jettyboot.mix.with.h2
Bundle-Version: 1.0.0
Fragment-Host: org.eclipse.jetty.osgi.boot
Import-Package: org.h2,org.h2.jdbcx

编辑

基于stacktrace，您可以使用JDBCLoginService。我刚刚快速浏览了一下，它在代码中使用了Class.forName（className）。我很抱歉，但我确信这对你不起作用

---

我不熟悉Jetty的这一部分，但正如我所看到的，有一个DataSourceLoginService。它可以使用预实例化的数据源，因此类加载不应该是一个问题。这可能对你有用。

不幸的是，这也不起作用。我还试图摆弄主机包的类路径。。。但是没有成功。你看到另一个选项了吗？附加信息：我用一个连接h2数据库的小豆扩展了jetty引导包-这很有效。因此，jetty引导包本身似乎看到了h2包。然而，jetty本身（代表jetty.security）没有看到h2.driver类。您能添加stacktrace吗？我已经在上面添加了stacktrace
