推荐答案
我在此帖子中发布了答案.我建议您更新问题，但是您发布了新问题，因为很难在评论中阅读.
I posted answer in this post. I suggested you to update the question, but you posted new question as It is hard to read in comment.
您需要在课堂上添加 Common Lang 2.6 jar 避免此异常的路径.
You need to add Commons Lang 2.6 jar in your class path to avoid this exception.
