我们有同一个 Web 应用程序的两个独立实例。一个是沙盒，一个是实时环境。两者都在访问 subversion，因此我们设置svnClientAdapter为使用 JavaHL。在我们正在调用的应用程序启动时JhlClientAdapterFactory.setup();

当第二个实例启动时，我收到错误消息：

Failed to load JavaHL Library.
These are the errors that were encountered:

很明显问题是什么，但我不知道如何解决它。

使用以下方法加载本机库svnClientAdapter：

System.loadLibrary(WINDOWSLIBS[i]);

您可以构建第三个“Web 应用程序”，其工作是加载服务器上部署的任何其他实例使用的本机库

我通过使用应用程序本身部署所需的 dll 来解决它。svnClientAdapter 也使用特殊属性subversion.native.library来查找 dll。因此，在初始化方法中，我使用以下方法获取应用程序运行的绝对路径：

String strPath = getClass().getClassLoader().getResource("someResourceThatExists").getPath();
strPath = strPath.replace("filenameOfResource");

之后我添加库的文件名并设置属性：

System.setProperty("subversion.native.library", strPath);

这似乎工作得很好。
