java 字符串组合成xml?

Question

xmlStr = "<?xml version='1.0' encoding='UTF-8'?><response><orders><order><orderid>"+ orderId+ "</orderid><account>"+ phone+ "</account><money>"+ money+ "</money></order></orders></response>";这是我组成的xml，怎么在页面显示的是6523438588534131526544501810.0，根本就不是xml文件啊，哪里有问题吗这个是页面的源码我把大于号和小于号用<和>代替了，但是，输出怎么还不是xml格式啊！！

Answer 1

输出的时候加个格式！！！
String xml = “你的xml”;
HttpServletResponse response = ServletActionContext.getResponse();
response.setCharacterEncoding("utf-8");
response.setContentType("text/xml;charset=UTF-8");//这里注意是xml
response.setHeader("Cache-Control", "no-cache");
response.getWriter().print(xml);
