### Question:
RaptorInterfaceUtils { public static String getInterfaceName(Class<?> type, Method method) { Class<?> interfaceClass = getInterfaceClass(type, method); return interfaceClass == null ? null : interfaceClass.getName(); }  static String getInterfaceName(Class<?> type, Method method); static Class<?> getInterfaceClass(Class<?> type, Method method); static List<Class<?>> findRaptorInterfaces(Class<?> clazz); static String getMethodSignature(Method method);  }### Answer:
@Test public void findMethod() { Method method = ReflectionUtils.findMethod(MoreServiceImpl.class, "testGet2", HelloRequest.class); String interfaceName = RaptorInterfaceUtils.getInterfaceName(MoreServiceImpl.class, method); System.out.println(interfaceName); Assert.assertEquals(MoreService.class.getName(), interfaceName); }
