            }
            else if(loctType.equalsIgnoreCase("name"))
            {
                loct = driver.findElement(By.name(loctValue));
            }
            else if(loctType.equalsIgnoreCase("tagname"))
            {
                loct = driver.findElement(By.tagName(loctValue));
            }

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println(e.getMessage());
        }
        return loct;

    }

无法解决...任何人都可以帮助我

请检查loctType，loctValue 不是null。在您的try catch 操作之前检查locter 是否也是not null 也很好。
