主要是继承HttpServletResponseWrapper写1个类(PageResponseWrapper),代码：
<div style="padding-right: 5px; padding-left: 4px; font-size: 13px; padding-bottom: 4px; width: 98%; padding-top: 4px; background-color: #eeeeee; border: #cccccc 1px solid;"><!----> 1 public class PageResponseWrapper extends HttpServletResponseWrapper {
 2     private Buffer buffer;
 3     private HttpServletResponse originalResponse;
 4 
 5     public PageResponseWrapper(final HttpServletResponse response){
 6         super(response);
 7         this.originalResponse = response;
 8         buffer = new Buffer();
 9     }
10 
11     @Override
12     public PrintWriter getWriter() throws IOException {
13         return buffer.getWriter();
14     }
15 
16     public CharArrayWriter getContent(){
17         return buffer.getBufferedWriter();
18     }
19 
20     public void close() throws IOException {
21         buffer.getWriter().close();
22     }
23     
24     public void finalize() throws Throwable {
25        super.finalize();
26        buffer.getWriter().close();
27     }
28 
29     /**
30      * 获取原始的response
31      * @return the originalResponse
32      */
33     public HttpServletResponse getOriginalResponse() {
34         return originalResponse;
35     }
36 }
