使用JSON字符串编写器而不是StringWriter将MustacheJava模板直接编译为JSON

我希望使用编写器将MustacheJava模板直接编译为JSON，编写器编写一个转义JSON字符串，而不是使用StringWriter然后执行toString

这是我目前的代码-

MustacheFactory mustacheFactory = new DefaultMustacheFactory();

// reader is my InputStreamReader pointing to my template file
Mustache mustache = mustacheFactory.compile(reader, "example");

StringWriter stringWriter = new StringWriter();
mustache.execute(stringWriter, view);
String html = stringWriter.toString();

// elementAdapter is a TypeAdapter<JsonElement>
elementAdapter.write(out, new JsonPrimitive(html));

JsonStringWriter的伪实现是-

public class JsonStringWriter extends Writer
{
  Writer writer;

  public JsonStringValueWriter(PrintWriter writer)
  {
    this.writer = writer;
  }

  @Override
  public void write(char[] cbuf, int off, int len)
  {
    // check cbuf for string escape characters
    // if found, write escape to underlying writer
    // otherwise, write cbuf to underlying writer
  }
}

我不想写这门课。我的问题是什么JSON API目前有这个类，您能提供对它的引用吗？谢谢

public class JsonStringWriter extends Writer
{
  Writer writer;

  public JsonStringValueWriter(PrintWriter writer)
  {
    this.writer = writer;
  }

  @Override
  public void write(char[] cbuf, int off, int len)
  {
    // check cbuf for string escape characters
    // if found, write escape to underlying writer
    // otherwise, write cbuf to underlying writer
  }
}
