我正在尝试在docx中搜索字符串，并使用java apache poi替换为其他文本，但是它是随机替换的在第

private static void replaceFormFieldText(XWPFDocument document, String ffname, String text) {
    boolean foundformfield = false;
    for (XWPFParagraph paragraph : document.getParagraphs()) {

                run.getCTR().getTList().get(0).setStringValue(text);
                // System.out.println(run.getCTR());
            }
        }
    }
}

public static void main(String[] args) throws Exception {

    XWPFDocument document = new XWPFDocument(new FileInputStream("WordTemplate.docx"));

    replaceFormFieldText(document, "Text1", "Моя Компания");
    replaceFormFieldText(document, "Text2", "Аксель Джоачимович Рихтер");
    replaceFormFieldText(document, "Text3", "Доверенность");

    document.write(new FileOutputStream("WordReplaceTextInFormFields.docx"));
    document.close();
}
}

它遗漏了一些字符串，不能替换整个文档。请提供示例代码帮助

我在https://github.com/centic9/poi-mail-merge的项目中进行了类似的操作，该项目提供了基于POI的常规邮件合并功能。它使用的功能与XmlBeans略有不同，该功能可以替换文档完整XML内容中的字符串，而不是分别替换每个段落。
