POI生成WORD文档

POI为Java系处理office文档的比较优秀的开源库，其中对于Excel的处理最为优秀，文档也写的很详细。不过很多网友都认为它在word文档处理方面就逊色很多，不过对于我本次的完成文档的生成我依然选择了POI。添加微信回复POI邀请你加群

需要完成功能

1. 配置Word模板文件，包括表格
2. 解析配置的Word文档，返回配置的特殊标记
3. 构造数据，替换配置的标签，以及生成表格

配置word模版

采用${xx}方式配置标签，如果是表格在对应一行一列配置表格名称

注意在word文档中，如果两个相近的字符样式不同，word默认会保存在不同的RUN元素中，由此很多朋友在配置好以后都需要保存为一个单独的文件，然后不把不在一起的标签合并到一个RUN元素中，如果文件比较大，我相信这绝对是一个比较痛苦的事情，这里将会侧重处理这个问题.我的解决方案是只保留第一RUN的样式其他的删掉

解析word模板

首先需要将文件转换为XWPFDocument对象，可以通过流的当时，也可以通过opcpackage,不过如果使用opcpackage打开的方式，打开的文件和最终生成的文件不能够是同一个文件，我这里采用文件流的方式

public XWPFDocument openDocument() {

        XWPFDocument xdoc = null;

        InputStream is = null;

        try {

            is = new FileInputStream(saveFile);

            xdoc = new XWPFDocument(is);

        } catch (IOException e) {

            e.printStackTrace();

        }

        return xdoc;

    }

获取非列表的标签，实现方式XWPFDocument对象有当前所有段落以及表格，这里暂不考虑表格嵌套表格的情况，每个段落的文本信息是可以通过p.getText()获取，获取段落中文档配置信息如下：

   // 获取段落集合中所有文本

    public List<TagInfo> getWordTag(XWPFDocument doc, String regex) {

        List<TagInfo> tags = new ArrayList<TagInfo>();

        // 普通段落

        List<XWPFParagraph> pars = doc.getParagraphs();

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

            XWPFParagraph p = pars.get(i);

            setTagInfoList(tags, p, regex);

        }

        // Table中段落

        List<XWPFTable> commTables = getDocTables(doc, false, regex);

        for (XWPFTable table : commTables) {

            List<XWPFParagraph> tparags = getTableParagraph(table);

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

                XWPFParagraph p = tparags.get(i);

                setTagInfoList(tags, p, regex);

            }

        }

        return tags;

    }

获取文本后通过正则解析，并依次保存到TagInfo中

// 向 taglist中添加新解析的段落信息

    private void setTagInfoList(List<TagInfo> list, XWPFParagraph p,

            String regex) {

        if (regex == "")

            regex = defaultRegex;

        Pattern pattern = Pattern.compile(regex);

        Matcher matcher = pattern.matcher(p.getText());

        int startPosition = 0;

        while (matcher.find(startPosition)) {

            String match = matcher.group();

            if (!list.contains(new TagInfo(match, match, ""))) {

                list.add(new TagInfo(match, match, ""));

            }

            startPosition = matcher.end();

        }

    }

解析表格

    // 获取Table列表中的配置信息

    public Map<String, List<List<TagInfo>>> getTableTag(XWPFDocument doc,

            String regex) {

        Map<String, List<List<TagInfo>>> mapList = new HashMap<String, List<List<TagInfo>>>();

        List<XWPFTable> lstTables = getDocTables(doc, true, regex);

        for (XWPFTable table : lstTables) {

            // 获取每个表格第一个单元格，以及最后一行

            String strTableName = getTableListName(table, regex);

            List<List<TagInfo>> list = new ArrayList<List<TagInfo>>();

            List<TagInfo> lstTag = new ArrayList<TagInfo>();

            int rowSize = table.getRows().size();

            XWPFTableRow lastRow = table.getRow(rowSize - 1);

            for (XWPFTableCell cell : lastRow.getTableCells()) {

                for (XWPFParagraph p : cell.getParagraphs()) {

                    // 去掉空白字符串

                    if (p.getText() != null && p.getText().length() > 0) {

                        setTagInfoList(lstTag, p, regex);

                    }

                }

            }

            list.add(lstTag);

            // 添加到数据集

            mapList.put(strTableName, list);

        }

        return mapList;

    }

生成WORD文档

难点替换标签
传入数据格式包含三个formtag以及一个tableTag

{"formTags":
  [{"TagName":"${xxxx}","TagText":"${xxxx}","TagValue":""},
   {"TagName":"${123}","TagText":"${123}","TagValue":""},
   {"TagName":"${ddd}","TagText":"${ddd}","TagValue":""}],
"tableTags":{ 
     "${table}":[
          [{"TagName":"${COL1}","TagText":"${COL1}","TagValue":""},{"TagName":"${COL2}","TagText":"${COL2}","TagValue":""}]
         ]}
    }

普通文档生成，并且保留配置样式，这里主要使用POI中提供searchText方法，返回Tag所有所在的RUN标签，通过一个字符做比较，如果找的第一个匹配的文本开始计数，所有在当前条件下类型 $${xxx}这样的标签是无法实现替换的
替换普通文本Tag

    public void ReplaceInParagraph(List<TagInfo> tagList, XWPFParagraph para,

            String regex) {

        if (regex == "")

            regex = defaultRegex;

        List<XWPFRun> runs = para.getRuns();

        for (TagInfo ti : tagList) {

            String find = ti.TagText;

            String replValue = ti.TagValue;

            TextSegement found = para.searchText(find,

                    new PositionInParagraph());

            if (found != null) {

                // 判断查找内容是否在同一个Run标签中

                if (found.getBeginRun() == found.getEndRun()) {

                    XWPFRun run = runs.get(found.getBeginRun());

                    String runText = run.getText(run.getTextPosition());

                    String replaced = runText.replace(find, replValue);

                    run.setText(replaced, 0);

                } else {

                    // 存在多个Run标签

                    StringBuilder sb = new StringBuilder();

                    for (int runPos = found.getBeginRun(); runPos <= found

                            .getEndRun(); runPos++) {

                        XWPFRun run = runs.get(runPos);

                        sb.append(run.getText((run.getTextPosition())));

                    }

                    String connectedRuns = sb.toString();

                    String replaced = connectedRuns.replace(find, replValue);

                    XWPFRun firstRun = runs.get(found.getBeginRun());

                    firstRun.setText(replaced, 0);

                    // 删除后边的run标签

                    for (int runPos = found.getBeginRun() + 1; runPos <= found

                            .getEndRun(); runPos++) {

                        // 清空其他标签内容

                        XWPFRun partNext = runs.get(runPos);

                        partNext.setText("", 0);

                    }

                }

            }

        }

        // 完成第一遍查找,检测段落中的标签是否已经替换完

        Pattern pattern = Pattern.compile(regex);

        Matcher matcher = pattern.matcher(para.getText());

        boolean find = matcher.find();

        if (find) {

            ReplaceInParagraph(tagList, para, regex);

            find = false;

        }

    }

表格主要是通过复制模版行，然后对模版行中的内容做修改
复制文本标签RUN

    private void CopyRun(XWPFRun target, XWPFRun source) {

        target.getCTR().setRPr(source.getCTR().getRPr());

        // 设置文本

        target.setText(source.text());

    }

复制段落XWPFParagraph

    private void copyParagraph(XWPFParagraph target, XWPFParagraph source) {

        // 设置段落样式

        target.getCTP().setPPr(source.getCTP().getPPr());

        // 添加Run标签

        for (int pos = 0; pos < target.getRuns().size(); pos++) {

            target.removeRun(pos);

        }

        for (XWPFRun s : source.getRuns()) {

            XWPFRun targetrun = target.createRun();

            CopyRun(targetrun, s);

        }

    }

复制单元格XWPFTableCell

    private void copyTableCell(XWPFTableCell target, XWPFTableCell source) {

        // 列属性

        target.getCTTc().setTcPr(source.getCTTc().getTcPr());

        // 删除目标 targetCell 所有单元格

        for (int pos = 0; pos < target.getParagraphs().size(); pos++) {

            target.removeParagraph(pos);

        }

        // 添加段落

        for (XWPFParagraph sp : source.getParagraphs()) {

            XWPFParagraph targetP = target.addParagraph();

            copyParagraph(targetP, sp);

        }

    }

复制行XWPFTableRow

    private void CopytTableRow(XWPFTableRow target, XWPFTableRow source) {

        // 复制样式

        target.getCtRow().setTrPr(source.getCtRow().getTrPr());

        // 复制单元格

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

            copyTableCell(target.getCell(i), source.getCell(i));

        }

    }

以上就完成所有功能更，只要你配置规范，可以完全原样输出模版内容。这里特别感谢下肖哥哥大力支持。

其次，java的编码真的让人很无语，get或post时中文各种乱码
