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

Question

我写了一个程序来读取我的Microsoft Word文档文件的内容.我的要求是获取word.doc的文档图,我开始阅读我的代码所在的doc文件.

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());
            }
        }

请检查您的类路径上是否有两个POI JAR副本.

如果是,请保留单一副本.
