/**
 * Variant of {@link #bindInterceptor(Class, Class...) bindInterceptor} that

 * @param classMatcher matches classes the interception should apply to.
 *   For example: {@code only(Runnable.class)}.
 * @param methodMatcher matches methods the interception should apply to.
 *   For example: {@code annotatedWith(Transactional.class)}.
 * @param methodInterceptorWrapper a wrapper applied to each of the specified interceptors.
 * @param methodInterceptorClasses chain of
 *   {@link org.aopalliance.intercept.MethodInterceptor MethodInterceptor}s
 *   used to intercept calls, specified by class.
