            //不能在最后的关闭括号
            我的网站没有允许它关闭
            HWPFDocument DOC =新HWPFDocument（FS）;
            WordExtractor我们=新WordExtractor（DOC）;
            的String [] =段we.getParagraphText（）;
            的System.out.println（Word文档有+
            paragraphs.length +段落）;
            的for（int i = 0; I＆LT;段落。长度;我++）{

            }
        }
        赶上（例外五）{
            e.printStackTrace（）;
        }
    }
}
 

解决方案

 的FileOutputStream FOS =新的FileOutputStream（filesname）;
doc.write（FOS）;
fos.close（）;
 

您可以尝试写入 POIFsFileSystem 以及

 的FileOutputStream FOS =新的FileOutputStream（filesname）;
fs.write（FOS）;
fos.close（）;
 

how to save the Doc file using the same name using POI API

public class readDoc {
    public static void main( String[] args ) {
        String filesname = "Hello.doc";
        POIFSFileSystem fs = null;
        try {
            fs = new POIFSFileSystem(new FileInputStream(filesname; 
            //Couldn't close the braces at the end as 
            my site did not allow it to close
            HWPFDocument doc = new HWPFDocument(fs);
            WordExtractor we = new WordExtractor(doc);
            String[] paragraphs = we.getParagraphText();
            System.out.println( "Word Document has " +
            paragraphs.length + " paragraphs" );
            for( int i=0; i<paragraphs .length; i++ ) {
                System.out.println("Length:"+paragraphs[i].length());
            }
        }
        catch(Exception e) { 
            e.printStackTrace();
        }
    }
}

解决方案

FileOutputStream fos = new FileOutputStream(filesname);
doc.write(fos);
fos.close();

You could try writing to the POIFsFileSystem as well.

FileOutputStream fos = new FileOutputStream(filesname);
fs.write(fos);
fos.close();
