Apache POI XWPF 不替换而是拼接

Question

我是 Apache POI 新手，在替换文本时遇到问题。

我在这里复制了我的代码Replacing a text in Apache POI XWPF not working

它可以工作，但它不会替换文本，而是将其连接起来。因此，如果我有 "Quick brown fox jumps over" 并将 "over" 替换为 "under"。我得到 "Quick brown fox jumps overQuick brown fox jumps under".

怎么了？

代码如下：

public class testPOI {

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

        String filepath = "F:\MASTER_DOC.docx";
        String outpath = "F:\Test.docx";

        XWPFDocument doc = new XWPFDocument(new FileInputStream(filepath));
        for (XWPFParagraph p : doc.getParagraphs()){

            int numberOfRuns = p.getRuns().size();

            // Collate text of all runs
            StringBuilder sb = new StringBuilder();
            for (XWPFRun r : p.getRuns()){
                int pos = r.getTextPosition();
                if(r.getText(pos) != null) {
                    sb.append(r.getText(pos));
                }
            }

            // Continue if there is text and contains "test"
            if(sb.length() > 0 && sb.toString().contains("test")) {
                // Remove all existing runs
                for(int i = 0; i < numberOfRuns; i++) {
                    p.removeRun(i);
                }
                String text = sb.toString().replace("test", "DOG");
                // Add new run with updated text
                XWPFRun run = p.createRun();
                run.setText(text);
                p.addRun(run);
            }
        }
       doc.write(new FileOutputStream(outpath));
    }
}

编辑 1：这很奇怪！我尝试在 2nd 运行上更换效果很好。第一个运行有问题。谁能指出来？

我试过了。有效。

    public class testPOI {

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

    String filepath = "F:\MASTER_DOC.docx";
    String outpath = "F:\Test.docx";

    XWPFDocument doc = new XWPFDocument(new FileInputStream(filepath));
    for (XWPFParagraph p : doc.getParagraphs()){

        int numberOfRuns = p.getRuns().size();

        // Collate text of all runs
        StringBuilder sb = new StringBuilder();
        for (XWPFRun r : p.getRuns()){
            int pos = r.getTextPosition();
            if(r.getText(pos) != null) {
                sb.append(r.getText(pos));
            }
        }

        // Continue if there is text and contains "test"
        if(sb.length() > 0 && sb.toString().contains("test")) {
            // Remove all existing runs
            for(int i = numberOfRuns; i >=0 ; i--) {
                p.removeRun(i);
            }
            String text = sb.toString().replace("test", "DOG");
            // Add new run with updated text
            XWPFRun run = p.createRun();
            run.setText(text);
            p.addRun(run);
        }
    }
   doc.write(new FileOutputStream(outpath));
}
}
