java - 线程 "main"java.lang.NoSuchFieldError : filesystem 中的异常

Question

我编写了一个程序来读取我的 Microsoft Word 文档文件的内容。实际上我的要求是获取 word.doc 的文档映射，我通过阅读 doc 文件开始我的代码是..

public static void readParagraphs(HWPFDocument doc) throws Exception
        {
            WordExtractor we = new WordExtractor(doc);
            /**Get the total number of paragraphs**/
            String[] paragraphs = we.getParagraphText();
            System.out.println("Total Paragraphs: "+paragraphs.length);
            for (int i = 0; i < paragraphs.length; i++) 
            {
                System.out.println("Length of paragraph "+(i +1)+": "+ paragraphs[i].length());
                System.out.println(paragraphs[i].toString());
            }
        }

请检查您的类路径中是否有两个 POI JAR 副本。

如果是，请保留一份副本。
