报错信息：UserWarning: find_elements_by_class_name is deprecated. Please use find_elements(by=By.CLASS_NAME, value=name) instead
  warnings.warn("find_elements_by_class_name is deprecated. Please use find_elements(by=By.CLASS_NAME, value=name) instead")

查询后发现该方法已经被弃用，需要用find_element()方法替代，使用方法如下：

driver.find_element(By.ID,"J_goodsList")
#想查的是id就写By.ID，是class就写CLASS_NAME
#感觉变动不是很大，也还挺方便

find_element()方法的源码如下：

    def find_element(self, by=By.ID, value=None):
        """
        Find an element given a By strategy and locator.

        :Usage:
            ::

                element = element.find_element(By.ID, 'foo')

        :rtype: WebElement
        """
        if by == By.ID:
            by = By.CSS_SELECTOR
            value = '[id="%s"]' % value
        elif by == By.TAG_NAME:
            by = By.CSS_SELECTOR
        elif by == By.CLASS_NAME:
            by = By.CSS_SELECTOR
            value = ".%s" % value
        elif by == By.NAME:
            by = By.CSS_SELECTOR
            value = '[name="%s"]' % value

        return self._execute(Command.FIND_CHILD_ELEMENT,
                             {"using": by, "value": value})['value']

最后记得导入这个包：
