code: public static <T> BeanQuery<T> select(Class<T> beanClass) {
      return new BeanQuery<T>(new BeanSelector<T>(beanClass));
    }
docs: Create a BeanQuery instance without the function of convert result into Map
  function. If you just want to filter bean collection, sort bean collection
  and want to get the execute result as a list of beans, you should use this
  method to create a BeanQuery instance.
