在单个smooks实例上应用advisitor时出现异常

Question

需要任何人的建议。

if you look at the below code,every time I am creating the new object for smooks as ftlname dynamically get populated.
        try {
              Smooks smooks1 = new Smooks("smooks-config.xml");
            if (ftlName != null) {
                inputStream = new ByteArrayInputStream(xmlMessage.toString()
                        .getBytes());
                outStream = new ByteArrayOutputStream();
                smooks1.addVisitor(new FreeMarkerTemplateProcessor(
                        new TemplatingConfiguration(ftlName)));
                smooks1.filterSource(new StreamSource(inputStream),
                        new StreamResult(outStream));
                resultString = outStream.toString();
                inputStream.close();
                outStream.close();
            }
        } catch (Exception ee) { }

这确实影响了性能，因为每次创建smooks对象时，当我尝试使用单个smooks实例时，都会出现以下错误。

java.lang.UnsupportedOperationException: Unsupported call to Smooks instance configuration method after Smooks instance has created an ExecutionContext.

can you please provide your advice on it.
smooks version :- 1.5.1

我的猜测(未经证实)是，您不能使用XML文件(在构造函数中)配置Smooks实例，然后继续通过addVisitor()添加更多的访问者隐含。

有没有什么原因你没有在smooks配置中配置freemarker模板？
