OSGi 在 .jar 中看不到类 - java.lang.NoClassDefFoundError答案

【问题标题】：OSGi can't see class in .jar - java.lang.NoClassDefFoundErrorOSGi 在 .jar 中看不到类 - java.lang.NoClassDefFoundError

【问题描述】：

我正在尝试将 .jar 安装到 CQ5 OSGi，但每当我尝试使用该包中的代码时，我都会收到此错误：

03.07.2013 08:47:05.650 *ERROR* [0:0:0:0:0:0:0:1 [1372834022135] GET /content/TEST_hartmann/testdfs.html HTTP/1.1] maven.test.dfs [info.hartmann.dfs.impl.Handler] Error during instantiation of the implementation object (java.lang.NoClassDefFoundError: com/emc/documentum/fs/datamodel/core/context/Identity) java.lang.NoClassDefFoundError: com/emc/documentum/fs/datamodel/core/context/Identity

在我的项目中，我使用了 30 多个位于该 jar 文件根目录中的外部（jar）库和 3 个我自己的位于 info/hartmann/dfs/impl 和 info/hartmann/dfs/api 中的类。这是我的 MANIFEST.MF

【问题讨论】：

你的 jar 文件是否包含在你的构建路径中？
@JREN “我的 jar 文件”是什么意思？我创建的 jar 或缺少该类的 jar？
您的 jar 中是否真的有库 jar 或者只是位于同一个地方？如果在您的 jar 中，该 AFAIK 将无法与标准类加载器一起使用。如果位于同一个地方，你的 bundle-classpath 是错误的。不了解 CQ5，但您通常在 OSGi 环境中所做的是将库安装为 OSGi 包并使用 Import-Package 来使用它们。
应该包含此类的 jar 文件。只有当您尝试访问在运行时不存在的类时才会抛出 NoClassDefFoundException。所以我假设你的项目中有 jar，但在你的构建路径中没有
@eis 我把它们放在一个 jar 文件中。

标签： java maven jar osgi

【解决方案1】：

不知道具体的 CQ5，但在 OSGi 容器中，您应该将库安装为单独的 OSGi 包并使用 Import-Package 将它们放入您的类路径中。

如果它们不支持 osgi，您需要找到 OSGified 版本，使用 bnd 工具将它们 osgified 或使用正确的手工 OSGi 清单文件打包它们。

【讨论】：

【解决方案2】：

在清单中，包 info.hartmann.dfs.impl 未列出，bnd（除非明确删除）将这些包列为 Private-Package。我也没有在 POM 中看到您如何包含您的私有包，因为您只使用 project.exports。

现在错误消息在这种情况下令人困惑......它表明 Handler 类存在但对 documentum API 不可见。不知道发生了什么...

【讨论】：

我的猜测是 info.hartmann.dfs.impl 是包含在同一个 jar 中的东西，即使没有私有包，也可能发现它带有 bundle-classpath。 Documentum API 在另一个 jar 中，因此常规类加载器无法找到它，因为它没有正确打包。
