服务器中带有CDATA的Xstream有IOException，但在Eclipse中有效

Question

我已经搜索并获得了为Axstream添加CDATA标签的解决方案，并且它在我的机器中的Eclipse中运行良好。但是，在我将代码部署到tomcat服务器之后，它始终在toXML（t，writer）或toXML（t）上失败并且IOException，我还尝试将编写器设置为＆＃34; UTF-8＆＃34 ;，但仍然没有运气。

处理CDATA的代码是：

XStream xstream = new XStream( new XppDriver(){
@Override
public HierarchicalStreamWriter createWriter(Writer out) {
  return new PrettyPrintWriter(out){
  boolean cdata = false;
  @Override
  public void startNode(String name) {
    super.startNode(name);
    cdata = name.equalsIgnoreCase("imagestream");
  }
  @Override
  protected void writeText(QuickWriter writer, String text) {
     if(cdata && !text.isEmpty()){
         writer.write("<![CDATA[");
         writer.write(text);
         writer.write("]]>");
     }else {
         writer.write(text);
  }
 }
};
}
}); 

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
PrintWriter writer = new PrintWriter(new OutputStreamWriter(outputStream, Charset.forName("UTF-8")));

xstream.toXML(t,writer);
xml = outputStream.toString("UTF-8");
