如何将流结果转换为字符串 [英] How to convert stream results to string
问题描述
在Junit中使用它我认为我需要使用字符串作者,但
我不知道如何使用它。 / p>
StreamResult result = new StreamResult(new File(C:\\\file.xml));
transformer.transform(source,result);
感谢

查看并学习使用StreamResult类的javadoc( http://java.sun.com/javase/6/docs/api/ )。
StreamResult的一个构造函数将Writer对象作为参数。你会看到Writer的一个子类是StringWriter。所以要从写入StreamResult的字符串中获取一个字符串,可以构造一个StringWriter,将它放入StreamResult,将Source转换为StreamResult,并从StringWriter获取字符串。
//为输出创建一个StringWriter
StringWriter outWriter = new StringWriter();
StreamResult result = new StreamResult(outWriter);
...
transformer.transform(source,result);
StringBuffer sb = outWriter.getBuffer();
String finalstring = sb.toString();
I want to convert the stream result output to string since I want to use it in Junit I think that I need to use the string writer but Im not sure how exactly to use it.
StreamResult result = new StreamResult(new File("C:\\file.xml"));
transformer.transform(source, result);
Thanks Fedor
Have a look at and learn to use the javadocs of the StreamResult class (http://java.sun.com/javase/6/docs/api/). One of the constructors of StreamResult takes a Writer object as a parameter. You will see that one of the sub-classes of Writer is StringWriter. So to obtain a string from what is written to the StreamResult, you can construct a StringWriter, put it into the StreamResult, transform() the Source to the StreamResult and get the string from the StringWriter.
//create a StringWriter for the output
StringWriter outWriter = new StringWriter();
StreamResult result = new StreamResult( outWriter );
...
transformer.transform( source, result );
StringBuffer sb = outWriter.getBuffer();
String finalstring = sb.toString();
