1.在spring base项目中，最好将配置类导入WebConfig类，该类将扩展

WebMVCConfigureAdapter

或

webmvcconfigurationsupport

2.在ServletInitializer类中，将webConfig类作为根就足够了配置类

public class AppInit extends AbstractAnnotationConfigDispatcherServletInitializer{
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{
                WebConfig.class
        };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
       return new Class<?>[]{

        };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

您是否尝试将SecurityConfig类导入WebConfig类？
