java - OutputStreamWriter java无法存储到字符串中

Question

transformer.transform(new DOMSource(doc),new StreamResult(new OutputStreamWriter(System.out, "UTF-8")));

我正在使用它来生成控制台的输出。我想将输出存储到一个刺痛中。我不知道该怎么做。谁能帮我？:(

提前致谢

Answer 1

例如使用这个（它避免编码字符串）：

StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String str = writer.getBuffer().toString();

Answer 2

使用StringWriter类而不是OutputStreamWriter.

Answer 3

一种解决方案可能如下所示：

ByteArrayOutputStream out = new ByteArrayOutputStream();
transformer.transform(new DOMSource(doc),new StreamResult(new OutputStreamWriter(out, "UTF-8")));
String string = new String(out.toByteArray(), "UTF-8");
