code: private static String[] getHttpMethodAndPath(Route route){

  			final List<String> methodAndPath = StrUtil.split(routeAnnotationValue, ':', 2);
  			httpMethod = methodAndPath.get(0).trim().toUpperCase();
  			path = fixPath(methodAndPath.get(1).trim());

docs: 从Route Annotation的值中获取Http Method和Path<br>
  例：
  Route("post:/example") -> {"POST", "/example"}
  Route("example") -> {null, "example"}
  Route("post:") -> {"POST", ""}
  @param route Route注解
  @return {httpMethod, path}
