Question

大约半天我试图找到一种方法将我在SpringSecurity上的实现迁移到OSGi（equinox）捆绑包 的上下文而不切换到SpringDM 。

目前我们有两个项目：

1。我有 Spring Security 的实现，它基于一些xml配置文件来处理身份验证和授权。
2。另一方面，我们有一个巨大的 OGSi捆绑项目结构，大约有200个捆绑包，需要与安全捆绑集成（上述一个）

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的的它为我准备了 Spring-DataSource.xml 和 Spring-Security.xml ，如下所示：

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

但不幸的是，这个异常发生了：

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，但是对于这个问题的唯一建议是针对SpringDM上的应用程序，但是我们的ProjectManager切换到SpringDM是不可接受的并且说实话我不知道SpringDM 。

请您帮我解决使用Spring Core功能的问题。

非常感谢莫因

你实际上并不需要Spring DM。它只是提供了OSGi和Spring之间的桥梁，还有一些细节，比如在OSGi环境中正确加载所有上下文文件。你也可以自己做，但你必须补偿类加载问题，这是你遇到的问题。

尝试此操作来修复类加载问题。

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

顺便说一下，你方法的第二行没有用处。

在没有SpringDM的OSGi应用程序中使用Spring Security
