java - java中如何将大字符串保存到xml文件中？

Question

我将一些大数据以 xml 格式加载到程序中的字符串中(来自 mysql)，当我将此字符串保存到 out.xml 中时，仅存储了大约 500 条记录。 如何将大字符串或其他数据保存到 xml 格式或任何其他格式的文件中？

这是我的代码:

    String xmlString = doExportIntoString();
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    InputSource source = new InputSource(new StringReader(xmlString));
    Document document =factory.newDocumentBuilder().parse(source);        
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer = tf.newTransformer();
    Result result = new StreamResult(new File("C:\\xmlFile.xml"));
    Source s = new DOMSource(document);
    transformer.transform(s, result);

这是上面代码的正确版本:

BufferedWriter out;
try {
    out = new BufferedWriter(new FileWriter("out.txt"));
    out.write("aString");
} catch (IOException e) {
    throw new RuntimeException(e);    
} finally {
    if (out != null) {
        try { out.close(); } catch (IOException e) {}
    }
}
