如何将字符串保存到csv文件？

[yinleiyoung]

现在Action中得到一个Service端返回的字符串 String test = “xxxxxxxxxxxxxx”, 现在要将它保存到一个CSV文件，文件名默认为test.csv,请问怎么实现？
谢谢！

对了，我还需要跳出 “下载” “保存” 对话框

[老紫竹]

out.clearBuffer();
String filename="test.csv";
response.addHeader("Content-Disposition", new String(("attachment; filename=" + filename).getBytes("GBK"), "ISO-8859-1"));
response.setContentType("application/vnd.ms-excel");
// 后面输出你的字符串吧

谢谢！
我现在碰到了乱码问题，我用的是UTF-8格式，英文操作系统，当有中文下载到CSV文件的时候，出现乱码

[robin_ares]

response.setContentType("application/text;charset="UTF-8");
response.setHeader("Content-disposition", "attachment;filename=11.csv");
DataOutputStream out;
try{
out = new DataOutputStream(response.getOutputStream());
out.write("AAAA".getBytes("UTF-8"));
out.close();
}......

to yangzi315,
我这里只有一个字符串String, 我不需要，也没有文件可以读取

[yangzi315]

解决乱码可以如下：
<%
java.io.BufferedInputStream bis=null;
java.io.BufferedOutputStream bos=null;
try{
String filename=request.getParameter("filename");
filename=new String(filename.getBytes("iso8859-1"),"gb2312");
response.setContentType("application/x-msdownload");
response.setHeader("Content-disposition","attachment; filename="+new String(filename.getBytes("gb2312"),"iso8859-1"));
bis =new java.io.BufferedInputStream(new java.io.FileInputStream(config.getServletContext().getRealPath("files/" + filename)));
bos=new java.io.BufferedOutputStream(response.getOutputStream());
byte[] buff = new byte[2048];
int bytesRead;
while(-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
bos.write(buff,0,bytesRead);
}
}
catch(Exception e){
e.printStackTrace();
}
finally {
if (bis != null)bis.close();
if (bos != null)bos.close();
}
%>
注意，关键就是setHeader里的filename需要重新编码,格式是ISO-8859-1就ＯＫ了
