本文介绍了一个自定义XStream实例的方法，通过此方法可以使得XStream支持CDATA格式的数据输出。通过对XStream的XppDriver进行扩展，并自定义PrettyPrintWriter来实现这一功能。

package com.broadengate.common.utils;

import java.io.Writer;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.core.util.QuickWriter;
import com.thoughtworks.xstream.io.HierarchicalStreamWriter;
import com.thoughtworks.xstream.io.xml.PrettyPrintWriter;
import com.thoughtworks.xstream.io.xml.XppDriver;

/**

public class XStreamCDATA {
protected static String PREFIX_CDATA = "<![CDATA[";
protected static String SUFFIX_CDATA = "]]>";

public XStream initXStream() {
  XStream xstream = new XStream(new XppDriver() {
   public HierarchicalStreamWriter createWriter(Writer out) {
    return new PrettyPrintWriter(out) {
     protected void writeText(QuickWriter writer, String text) {
      if (text.startsWith(PREFIX_CDATA)
        && text.endsWith(SUFFIX_CDATA)) {
       writer.write(text);
      } else {
       super.writeText(writer, text);
      }
     }
    };
   };
  });
  return xstream;
}
}
