.doc文件

代码中的WordParagraph类是自己创建的实体类,用于记录文本信息和图片

file_word对象为前台上传的MultipartFile对象.

// doc格式

List wordParagraphs=new ArrayList<>();

HWPFDocument doc = new HWPFDocument(file_word.getInputStream());

Range range = doc.getRange();

int numP = range.numParagraphs();

//StringBuffer ret = new StringBuffer();

for (int i = 0; i < numP; ++i) {

//从每一段落中获取文字

Paragraph p = range.getParagraph(i);

//ret.append(p.text());

WordParagraph wordParagraph=new WordParagraph(p.text(),i);

wordParagraph.init();

wordParagraphs.add(wordParagraph);

}

// List pictsList = new ArrayList();

// 得到文档的数据流

byte[] dataStream = doc.getDataStream();

int numChar = range.numCharacterRuns();

Integer paragraphOrder=0;

PicturesTable pTable = new PicturesTable(doc, dataStream, new byte[1024]);

for (int j = 0; j < numChar; ++j) {

CharacterRun cRun = range.getCharacterRun(j);

boolean has = pTable.hasPicture(cRun);

String[] temp_array=(cRun.toString()+" ").split("\r");

paragraphOrder=paragraphOrder+temp_array.length-1;

if (has) {

Picture picture = pTable.extractPicture(cRun, true);

if(paragraphOrder

wordParagraphs.get(paragraphOrder).addPictures(picture);

}

}

}

当前处理方式存在一些局限性

无法确定图片在段落的具体位置信息.(该问题可通过对文档流处理的优化解决)

如果一个段落有多个图片,可能只解析一个

.docx

网上对标签解析的方式,实测不可行.poi实际有提供获取的方法.

同样的,无法获取图片在段落的具体位置

.doc和.docx读取的图片类不是同一个,兼容的时候需要注意.

// docx格式

XWPFDocument document=new XWPFDocument(file_word.getInputStream());

List XWPFParagraphList=document.getParagraphs();

//List picList = document.getAllPictures();

for (int i = 0; i < XWPFParagraphList.size(); ++i) {

//从每一段落中获取文字

XWPFParagraph p = XWPFParagraphList.get(i);

WordParagraph wordParagraph=new WordParagraph(p.getParagraphText(),i);

List pictureList=readImageInfoInParagraph(p);

wordParagraph.setPictures(pictureList);

wordParagraph.init();

wordParagraphs.add(wordParagraph);

}

//获取某一个段落中的所有图片

public static List readImageInfoInParagraph(XWPFParagraph paragraph) {

List res=new ArrayList<>();

//段落中所有XWPFRun

List runList = paragraph.getRuns();

for (XWPFRun run : runList) {

List pictures=run.getEmbeddedPictures();

for(int i=0;i

res.add(pictures.get(i).getPictureData());

}

}

return res;

}
