大约有半天的时间，我试图找到一种方法将我在 SpringSecurity 上的实现迁移到 OSGi(equinox) 包的上下文而不切换到 SpringDM。


目前我们有两个项目：

1.我有一个基于一些xml配置文件的Spring Security的实现来处理认证和授权。
2.另一方面，我们有一个庞大的OGSi 捆绑项目结构，其中包含大约 200 个捆绑包，需要与安全捆绑包（如上所述的那个）集成


作为创建mySpringBasedSecurityBundle 的第一步，我需要在加载 mySecurityBundle 后运行此方法以访问位于以下位置的安全配置 xml 文件：com/myComp/backend/appsecurity/spring/resources/Spring-Context.xml ，它为我准备了Spring-DataSource。 xml和Spring-Security.xml如下：

    private void loadApplicationContext()
    {
        SecurityContextHolder.setStrategyName(SecurityContextHolder.MODE_GLOBAL);
        new ThreadLocal<Object>();
        setApplicationContext(new ClassPathXmlApplicationContext(SPRING_CONTEXT_ADDRESS));
    }



但不幸的是，发生了这个异常：

org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [com/myComp/backend/appsecurity/spring/resources/Spring-Context.xml]; nested exception is java.io.FileNotFoundException: class path resource [com/myComp/backend/appsecurity/spring/resources/Spring-Context.xml] cannot be opened because it does not exist

尽管我在网上搜索，对于这个问题的唯一建议是在 SpringDM 上的应用程序，但我们的 ProjectManager 切换到 SpringDM 是不可接受的，老实说我对 SpringDM 不了解。

请您使用 Spring Core 功能帮助我解决此问题。


非常感谢

您实际上并不需要 Spring DM。它只是在 OSGi 和 Spring 之间提供了一座桥梁，并提供了一些细节，例如在 OSGi 环境中正确加载所有上下文文件。您也可以自己执行此操作，但您必须补偿类加载问题，这是您遇到的问题。

试试这个来解决你的类加载问题。

ApplicationContext ctx = new ClassPathXmlApplicationContext(myCtxPath)
{
    protected void initBeanDefinitionReader(XmlBeanDefinitionReader reader)
    {
        super.initBeanDefinitionReader(reader);
        reader.setValidationMode(XmlBeanDefinitionReader.VALIDATION_NONE);
        reader.setBeanClassLoader(getClassLoader());
    }
}

顺便说一句，您方法的第二行毫无用处。
