Question

我有json文件，我使用Gson库将json对象解析为java对象。下一步是创建主类，其中在Apache POI的帮助下，读取了准备好的docx文件，在文本中进行了一些更改，并创建了带有更改的新文档。我遇到的问题是应该更改的文本需要是可变的（来自json文件）。我的意思是＆＃34; name＆＃34;和＆＃34; testName＆＃34;两者都应该是变量或方法，所以我可以从text.contains中调用它们。你能否表明我的错误和正确的方法来完成任务。提前致谢。这是我的代码`

 public class main {
 public static void gson() {
    Gson gson = new Gson();
    BufferedReader br = null;

    try {
        br = new BufferedReader(new FileReader("jsonn.json"));
        Result result = gson.fromJson(br, Result.class);
        if (result != null) {

            result.getName();
            result.getLastname();
            System.out.println(result.getName());
            System.out.println(result.getLastname());
            for (Phone p : result.getPhones()) {
                p.getType();
                p.getNum();
                System.out.println(p.getType() + ": " + p.getNum());
                // System.out.println(p.getType()+" : "+p.getNum());
            }

        }
    } catch (FileNotFoundException e) {

        e.printStackTrace();
    } finally {
        if (br != null) {
            try {
                br.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}}

                    r.setText(text, 0);
                }
            }
        }
    }
    for (XWPFTable tbl : doc.getTables()) {
        for (XWPFTableRow row : tbl.getRows()) {

                        String text = r.getText(0);
                        if (text != null && text.contains("name")) {
                            text = text.replace("name", "Alex");
                            r.setText(text, 0);
                        }
                    }
                }
            }
        }
    }
    doc.write(new FileOutputStream("Пример.docx"));

}}

`

这是json文件：

{
"name":"testName",
"lastname":"testLastName",
"phones":[
{
  "num":"9000000",
  "type":"mobile"
},
{
  "num":"1000000",
  "type":"home"
} ]}

扫描文档中的某些文本，替换某些单词（这些单词应该是变量）并使用Java中的Apache POI保存到新文档中
