解决poi操作docx替换${}占位符不成功的过程

代码:

public static OutputStream replaceBySteam(InputStream srcStream, String destPath, Map<String, String> map,String name,String id,HttpServletResponse response) throws Exception {
            XWPFDocument document = new XWPFDocument(srcStream);
        return replace(document, destPath, map, name, id, response);

    }

        OutputStream outStream = null;
        try {

出错原因:

在段落替换部分，最小单位是XWPFRun，XWPFRun是一个XML节点，包含了各种样式，属性和文字

2.从XWPFRun中取出文字进行替换，失败的原因就是：${变量}被分割在了数个XWPFRun里面，替换失败

解决方法

1.word打开原docx文件，取消各种拼写检查，另存为 xml文件

2.文本编辑器打开xml，找到要替换的属性占位符，手动处理.

3.保存xml，用word打开xml，另存为，docx.

如果还不行,可以在换一种段落的替换方式.

第一种:

while (itPara.hasNext()) { // XWPFParagraph paragraph = (XWPFParagraph) itPara.next(); // Set<String> set = map.keySet(); // Iterator<String> iterator = set.iterator(); // while (iterator.hasNext()) { // String key = iterator.next(); // List<XWPFRun> run = paragraph.getRuns(); // for (int i = 0; i < run.size(); i++) { // if (run.get(i).getText(run.get(i).getTextPosition()) != null && // run.get(i).getText(run.get(i).getTextPosition()).equals(key)) { // /** // * 参数0表示生成的文字是要从哪一个地方开始放置,设置文字从位置0开始 // * 就可以把原来的文字全部替换掉了 // */ // run.get(i).setText(map.get(key), 0); // } // } // } // }

第二种:

while (itPara.hasNext()) { XWPFParagraph paragraph = itPara.next(); List<XWPFRun> runs = paragraph.getRuns(); for (XWPFRun run : runs) { String oneparaString = run.getText(run.getTextPosition()); if (StringUtils.isBlank(oneparaString)){ continue; } for (Map.Entry<String, String> entry : map.entrySet()) { if(entry.getValue()!=null){ oneparaString = oneparaString.replace(entry.getKey(), entry.getValue()); } } run.setText(oneparaString, 0); } }
