我有一个包含数百个捆绑包的 RCP 应用程序，这些捆绑包与 Spring dm 连接。升级到 Spring 3.2.1 后，我现在在几个捆绑包中得到以下异常。起初我认为这可能是由 dm 中的一些魔法引起的，但在通过初始化没有 dm 的包（只需以编程方式启动 ApplicationContext）来测试该理论之后，我仍然面临同样的异常。

原始清单是 Require-Bundle 和 Package-Import 的混合体，所以我尝试完全删除 Require-Bundle。没想到这会改变任何事情，但绝望的时代需要绝望的措施，我是对的，仍然一无所获。

作为最后的手段，我也尝试添加这个属性，仍然没有改变。

DynamicImport-Package: *

我知道 Spring 在 3.1 版左右改变了他们对 cglib 的使用，将 cglib 和 asm 嵌入到他们的核心 jar 中，但是我已经包含了所有 cglib 和 asm 包的导入，但无济于事。

更新：我现在意识到只有在使用查找方法注入时才会出现这种特殊情况。由于我仍然不知道如何修复它，我不得不更改配置以不使用此功能。

我们通过将 org.springframework.cglib 等的 import-package 添加到 org.springframework.transaction 包中解决了类似的问题。

似乎在 Spring 3.2 中他们改变了内部类结构。使用默认的 OSGI 包，找不到这些 clib 类。因此，您必须在 MANIFEST.MF 中明确指定您需要在上下文中加载这些包。

您可以在 jar 文件中编辑 MANIFEST.MF 文件。在 Import-Package 部分添加以下 3 个包：

'org.springframework.cglib.core','org.springframework.cglib.proxy','org.springframework.beans.factory'

或者，如果您使用的是 gradle，您可以执行以下操作（假设您已经启用了 osgi 插件）

jar { manifest { instruction 'Import-Package', 'org.springframework.cglib.core', 'org.springframework.cglib.proxy', 'org.springframework.beans.factory', '*' } }
