不过采用resin服务器的话，以上代码会失效。因为resin没有实现getWriter方法，而是采用getOutputStream取而代之，所以必须修改些代码来迎合resin运行环境：
/** * START File FileCaptureResponseWrapper.java */
package com.junjing.filter;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class FileCaptureResponseWrapper
extends HttpServletResponseWrapper
{
private CharArrayWriter output;
public String toString()
{
return output.toString();
}
public FileCaptureResponseWrapper(HttpServletResponse response)
{
super(response);
output = new CharArrayWriter();
}
public PrintWriter getWriter()
{
return new PrintWriter(output);
}
public void writeFile(String fileName)
throws IOException
{
FileWriter fw = new FileWriter(fileName);
fw.write( output.toString());
fw.close();
}
public ServletOutputStream getOutputStream()
throws java.io.IOException
{
return new ServletOutputStream();
}
public void write(int b)
throws IOException
{
output.write(b);
}
public void write(byte b[])
throws IOException
{
output.write(new String(b,"GBK"));
}
public void write(byte b[], int off, int len)
throws IOException
{
output.write(new String(b, off, len));
}
};
}
public void writeResponse(PrintWriter out)
{
out.print(output.toCharArray());
}
}
