如何强制javax xslt转换器使用utf-8而不是html实体编码国家字符? [英] How to force javax xslt transformer to encode national characters using utf-8 and not html entities?

问题描述

我正在研究应该使用某些样式表转换输出的过滤器.代码的重要部分如下所示:

I'm working on filter that should transform an output with some stylesheet. Important sections of code looks like this:

PrintWriter out = response.getWriter();
...
StringReader sr = new StringReader(content);
Source xmlSource = new StreamSource(sr, requestSystemId);
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
transformer.setParameter("encoding", "UTF-8");
//same result when using ByteArrayOutputStream xo = new java.io.ByteArrayOutputStream();
StringWriter xo = new StringWriter();
StreamResult result = new StreamResult(xo);
transformer.transform(xmlSource, result);
out.write(xo.toString());

问题在于，国家字符被编码为html实体，而不是使用UTF.有什么方法可以强制变压器使用UTF-8而不是实体?

The problem is that national characters are encoded as html entities and not by using UTF. Is there any way to force transformer to use UTF-8 instead of entities?

推荐答案

您需要将输出方法设置为text，而不是(默认)xml.

You need to set the output method to text instead of (default) xml.

transformer.setOutputProperty(OutputKeys.METHOD, "text");

但是，您还应该预先设置响应编码:

You should however also set the response encoding beforehand:

response.setCharacterEncoding("UTF-8");

并指示网络浏览器使用相同的编码:

And instruct the webbrowser to use the same encoding:

response.setContentType("text/html;charset=UTF-8");
