实施oauth2系统，我在使用以下代码时遇到一些问题：
import org.springframework.security.oauth2.provider.endpoint.FrameworkEndpointHandlerMapping;
import org.springframework.web.servlet.HandlerMapping;
...
HandlerMapping.class.isAssignableFrom(FrameworkEndpointHandlerMapping.class);
确实，作为班级FrameworkEndpointHandlerMapping正在实现接口HandlerMapping，这个函数应该总是返回true。当我对此函数运行单元测试时就是这种情况。但是，在服务器启动期间，该函数返回false（使用调试器检查）。这是一个很大的问题，因为当DispatcherServlet被实例化后，它会搜索实现的类HandlerMapping and my FrameworkEndpointHandlerMapping被丢弃会导致应用程序中出现错误。
我搜索过类似这个问题的其他问题，但大多数人的回答是isAssignableFrom方法未正确使用（类和函数参数的混合）。这里的情况并非如此，因为 JUnit 正在工作。
怀疑是进口的jar文件是问题所在，我将它们限制为以下文件：
- spring-beans-4.1.4.RELEASE.jar
- spring-security-oauth2-2.0.6.RELEASE.jar
- spring-webmvc-4.1.4.RELEASE.jar（也尝试过4.0.9）
- spring-core-4.1.4.RELEASE.jar
- ...
您有什么解决方案可以探索吗？

Specifies the location for Spring MVC to load an additional XML configuration file.
Because hybris is already configured with the XML spring configuration files to load
we must set this param value to EMPTY in order to prevent loading of the default

The web-application-config.xml导入所有配置文件（其中，oauth配置文件）。其中一个有一个<mvc:annotation-driven />启用 mvc 注释。
