为公司内部开发了1个简单的MVC框架，框架中需要向所有JSP页面的<head>中插入2条引用JS的代码，实现如下：
主要是继承HttpServletResponseWrapper写1个类(PageResponseWrapper),代码：
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 &nbs
只需从数据库查出来后在显示的地方用<pre></pre>标签修饰，如下：
<!--
<div style="font-size:12px;color:green;text-align:left">
<pre>
<%=
&n ......
