这个错误信息显示了一个Java Web应用程序中的错误，具体来说是一个空指针异常（NullPointerException）。该异常的根本原因可能是在Java代码中尝试使用一个null对象。您可以通过查看堆栈跟踪（stack trace）中的代码行号来确定问题出现在哪个Java类和方法中。首先，您可能需要检查在哪个Java类中的哪个方法导致了这个错误，然后检查该方法中的哪些变量或对象可能为空。如果您可以提供更多的代码和上下文信息，我可能可以提供更具体的建议。

It seems like you have provided an error message related to a Java web application. Can you provide more context or information about the issue you are facing?

您需要将函数调用放到函数外部或将函数定义在外部，可以按照以下代码进行修改：

import jieba 
from openpyxl import load_workbook 
from pyecharts.charts import WordCloud 

def info_analysis(ws, col):
    '''
    返回xlsx工作表中某一列分词后的统计结果
    :param ws:工作表
    :param col:工作表中的某列
    ：return：分词字典，键值分别表示分词及其出现的次数
    '''
    col_list = [item.value for item in ws[col][1:]]  #表示工作表 ws 第 col 列的数据,并去掉表头
    col_str = ",".join(col_list)  #将列表合并成字符串
    words = jieba.lcut(col_str)  #对字符串进行分词
    lcut_dict = {}  #用于统计分词的字典
    for word in words:
        if len(word) == 1:  #分词长度为1时不予统计
            continue
        else:
            lcut_dict[word] = lcut_dict.get(word, 0) + 1
    return lcut_dict

wb = load_workbook("D:\\行业信息.xlsx")
ws = wb["行业信息"]
require_dict = info_analysis(ws, "E") #对招聘要求进行分词统计
welfare_dict = info_analysis(ws, "F") #对企业福利进行分词统计
require_wc = (WordCloud()  #绘制词云图存储在require. html中
              .add("招聘要求", require_dict.items())
              .render("D:\\require.html")
             )
welfare_wc = (WordCloud()  #绘制词云图存储在welfare. html中
              .add("企业福利", welfare_dict.items())
              .render("D:\\welfare.html")
             )
print("词云图绘制成功")

另外，注意到代码中 `Len` 应该为 `len`，大小写拼写错误会导致程序报错。
