jsp生成静态页面的方法

复制代码 代码如下:

import java.io.ByteArrayOutputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStreamWriter; import java.io.PrintWriter; import javax.servlet.RequestDispatcher; import javax.servlet.ServletContext; import javax.servlet.ServletException; import javax.servlet.ServletOutputStream; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpServletResponseWrapper; public class toHtml extends HttpServlet {     public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException     {     String url="";     String name="";         ServletContext sc = getServletContext();         String file_name=request.getParameter("file_name");//你要访问的jsp文件,如index.jsp   //则你访问这个servlet时加参数.如http://localhost/toHtml?file_name=index         url = "/"+file_name+".jsp";//这是你要生成HTML的jsp文件,如                                    //http://localhost/index.jsp的执行结果.         name="/home/resin/resin-2.1.6/doc/"+file_name+".htm";//这是生成的html文件名,如index.htm.         RequestDispatcher rd = sc.getRequestDispatcher(url);         final ByteArrayOutputStream os = new ByteArrayOutputStream();         final ServletOutputStream stream = new ServletOutputStream()         {             public void write(byte[] data, int offset, int length)             {                 os.write(data, offset, length);             }             public void write(int b) throws IOException             {                 os.write(b);             }         };         final PrintWriter pw = new PrintWriter(new OutputStreamWriter(os));         HttpServletResponse rep = new HttpServletResponseWrapper(response)         {             public ServletOutputStream getOutputStream()             {                 return stream;             }             public PrintWriter getWriter()             {                 return pw;             }         };         rd.include(request, rep);         pw.flush();                FileOutputStream fos = new FileOutputStream(name); //把jsp输出的内容写到xxx.htm         os.writeTo(fos);         fos.close();         PrintWriter out=response.getWriter();         out.print("<p align=center><font size=3 color=red>首页已经成功生成！Andrew</font></p>");     } }
