在操作excel表格时,因为 存在 Excel2003和Excel2007两种版本的excel表格,所有如果jar包引入不够,会报一些异常,如: 执行到这一样时:new XSSFWorkbook(stream); 异常:Caused by: java.lang.ClassNotFound Exception : org.apache. xml beans. Xml Exception 这个异常时因为缺少jar包,jar包的名字是: xml beans-2.3.0.jar 解决了这个以后,还可能会出现另一个异常: Caused by: java.lang.ClassNotFound Exception : org.open xml formats.schemas.spreadsheetml.x2006.main.CTSheet 这个是因为,使用POI中的XSSFWorkbook操作excel2007(xlsx)的时候抛出的异常: 解决方案: poi包中默认不支持excel2007,如果需要解析,则需要引入poi-oo xml -schemas-xx.jar包。 引入此包后,可能还会有个异常,原因是找不到dom4j的jar包。 因为poi-oo xml -schemas-xx.jar需要依赖dom4j-xxx.jar包

好的,我可以回答您的问题。 针对您的需求,您可以使用Java和Spring Boot来编写一个RESTful API接口,该接口可以接收docx文件和关键词作为输入,并对上传的文件进行扫描以计算关键词的出现次数。 以下是该接口的代码示例: @PostMapping("/countKeywords") public ResponseEntity<String> countKeywords(@RequestParam("file") MultipartFile file, @RequestParam("keyword") String keyword) { try { // 将上传的docx文件转换为文本 String content = readDocxFile(file); // 计算出现次数 int count = countKeywordOccurrences(content, keyword); // 返回结果 return ResponseEntity.ok("关键词 '" + keyword + "' 在文档中出现了 " + count + " 次。"); } catch ( Exception e) { e.printStackTrace(); return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("出现了一些问题,请稍后重试。"); private String readDocxFile(MultipartFile file) throws IO Exception , Xml Exception { XWPFDocument doc = new XWPFDocument(file.getInputStream()); XWPFWordExtractor extractor = new XWPFWordExtractor(doc); return extractor.getText(); private int countKeywordOccurrences(String content, String keyword) { String[] words = content.split("\\W+"); int count = 0; for (String word : words) { if (word.equalsIgnoreCase(keyword)) { count++; return count; 在这个示例代码中,我们首先定义了一个POST请求处理器,该处理器的路由地址为"/countKeywords"。这个处理器接收两个参数,一个是上传的文件,另一个是待查询的关键词。 接着,我们调用了两个辅助函数。第一个函数`readDocxFile()`将上传的docx文件转换为文本格式,以便我们进行关键词的查询。第二个函数`countKeywordOccurrences()`是关键词出现次数的计算函数,它通过将文本拆分为单词,并逐个比较单词与关键词的值来计算关键词的出现次数。 最后,我们将处理结果封装为一个字符串并发送回客户端。 希望这个代码示例能够帮助您解决问题,如有任何疑问,欢迎随时向我提问。
