使用EasyPoi导出 word文件出现 Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError

问题遇到的现象和发生背景

最近在写项目 需要生成.doc的文件 在网上寻找到了EasyPoi
在测试类里运行成功
但是到ssm框架里 网页运行就报错

问题相关代码，请勿粘贴截图

 public String CreatPaper(String Subject,String FileName) throws Exception {
        List<Question> questions = questionService.queryQuestionBySubject(Subject);
        System.out.println(Subject+FileName);
        List<XWPFDocument> wordList = new ArrayList<>();
        for (int i = 0;i<questions.size();i++) {
            Question question = questions.get(i);
            Map<String, Object> map = new HashMap<String,Object>();
            System.out.println(question.getQuestion());
            map.put("Question_Id",question.getQuestion_Id());
            map.put("Question",question.getQuestion() );
            map.put("OptionA",question.getOptionA());
            map.put("OptionB",question.getOptionB());
            map.put("OptionC",question.getOptionC());
            map.put("OptionD",question.getOptionD());
            System.out.println("dddd");
            XWPFDocument doc = WordExportUtil.exportWord07("D:\\360安全浏览器下载\\20211022160107_114.docx", map);
            wordList.add(doc);
        }

运行结果及报错内容

我的解答思路和尝试过的方法

我想要达到的结果

cn/afterturn/easypoi/word/WordExportUtil
类找不到是不是存在依赖冲突了。
