POI之Word转化为Markdown-yellowcong

来源：互联网发布：如何选购家具知乎编辑：程序博客网时间：2024/06/09 15:35

Markdown最近特别的火，同时我也想把自己以前做的笔记（用doc写的）分享出来，所以我想将DOC解析，然后生成Markdown文件，然后通过代码直接将图片上传到七牛云，将文本数据传到野狗云和CSND,为啥我喜欢用七牛和野狗呢，因为他们都有免费的份额。PS(没有写完)

环境搭建

获取标题等级

Doc中的标题有等级，对应的我们的Markdown中也存在等级的操作

/**一级标题  begin */private static final String STYLE_TITLE_FONT_FONTNAME_1 ="宋体";private static final Integer STYLE_TITLE_FONT_SIZE_1 =48;private static final Integer TITLE_LV_1 = 1;/**一级标题  end *//**二级标题  begin */private static final String STYLE_TITLE_FONT_FONTNAME_2 ="Arial";private static final Integer STYLE_TITLE_FONT_SIZE_2 =32;private static final Integer TITLE_LV_2 = 2;/**二级标题  begin *//**三级标题  begin */private static final String STYLE_TITLE_FONT_FONTNAME_3 ="Times New Roman";private static final Integer STYLE_TITLE_FONT_SIZE_3 =32;private static final Integer TITLE_LV_3 = 3;/**三级标题  begin *//**普通的文本，不是标题*/private static final Integer TITLE_LV_0 = 0;/** * 获取标题的等级 * @param paragraph * @return 1、2、3三个等级，如果没有数据返回，那么等级为0 ，是普通文本 */private static Integer getTitleLvl(Paragraph paragraph) {    //获取这一段文字的数目    int charCnts = paragraph.numCharacterRuns();    int titleLv = TITLE_LV_0;    if(charCnts == 0){        return TITLE_LV_0;    }    CharacterRun characterRun = paragraph.getCharacterRun(0);    if(characterRun != null){        //字体的名称        String fontName =characterRun.getFontName();        //字体大小        int fontSize = characterRun.getFontSize();        //一级标题的情况        if(fontName.equals(STYLE_TITLE_FONT_FONTNAME_1) && fontSize == STYLE_TITLE_FONT_SIZE_1){            //System.out.println("一级标题\t"+paragraph.text().trim());            titleLv= TITLE_LV_1;        }else if(fontName.equals(STYLE_TITLE_FONT_FONTNAME_2) && fontSize == STYLE_TITLE_FONT_SIZE_2){            titleLv= TITLE_LV_2;//              System.out.println("\t二级标题\t"+paragraph.text().trim());        }else if(fontName.equals(STYLE_TITLE_FONT_FONTNAME_3) && fontSize == STYLE_TITLE_FONT_SIZE_3){            titleLv= TITLE_LV_3;            //System.out.println("\t\t三级标题\t"+paragraph.text().trim());        }    }    return titleLv;}

获取每行文字的每段落字符的样式

Markdown中的文字都是存在样式的，所以每一行都是有不同的样式，通过Range获取CharacterRun （这个类中包含了字体信息）

// 获取段落数，一个回车符号就是一个段落了int paraNum = range.numParagraphs();System.out.println(paraNum);for (int i = 0; i < paraNum; i++) {    //获取段落    Paragraph paragraph =range.getParagraph(i);    //获取这一段文字的数目    int charCnts = paragraph.numCharacterRuns();    if(charCnts == 0){        return;    }    //获取标题的级别，是一级 二级，三级的情况 , 0是普通文本    int titleLev = getTitleLvl(paragraph);    //源码中，有类似的写法，具体为啥判断是否》=-1不是特别清楚    int skipUntil = -1;    for (int c = 0; c < range.numCharacterRuns(); c++) {        //CharacterRun 会根据字体和样式，自动的字符分割开        CharacterRun characterRun = range.getCharacterRun(c);        if (characterRun != null && characterRun.getStartOffset() >= skipUntil) {            String text = characterRun.text();            String fontName = characterRun.getFontName();            int fontSize = characterRun.getFontSize();            int fontColor = characterRun.getColor();            boolean bold = characterRun.isBold();            boolean italic= characterRun.isItalic();            System.out.printf("当前文字的字体名称：%s,字体大小%d,字体颜色%d,加粗%b,斜体%b\r\n",text,fontName,fontSize,fontColor,bold,italic);        }    }    //图片处理    //表格处理}
