一，先建一個Java Web項目，並在WebRoot 下面新建一個test.jsp頁面

<%@ page language="java" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> </head> <body> ${name } </body> </html>

二創建一個工具類 CreateHTMLUtli.java

package com.createhtml.util; 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.ServletOutputStream; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpServletResponseWrapper; public class CreateHTMLUtli { public static void createHTML4Mapping(HttpServletRequest request,HttpServletResponse response,String jsp_url,String html_ulr) { FileOutputStream fos = null; try { RequestDispatcher rd = request.getRequestDispatcher(jsp_url); final ByteArrayOutputStream baos = new ByteArrayOutputStream(); final ServletOutputStream sos = new ServletOutputStream() { public void write(byte[] b, int off, int len) throws IOException { baos.write(b, off, len); } public void write(int b) throws IOException { baos.write(b); } }; final PrintWriter pw = new PrintWriter(new OutputStreamWriter(baos)); HttpServletResponse rep = new HttpServletResponseWrapper(response) { public ServletOutputStream getOutputStream() { return sos; } public PrintWriter getWriter() throws IOException { return pw; } }; rd.include(request, rep); pw.flush(); fos = new FileOutputStream(html_ulr); baos.writeTo(fos); } catch (Exception e) { } finally { if(fos != null) { try { fos.close(); } catch (IOException e) { } } } } }

三，創建 Servlet

package com.createhtml.servlet; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.createhtml.util.CreateHTMLUtli; @SuppressWarnings("serial") public class CreateHTMLServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doPost(request, response); } @SuppressWarnings("deprecation") public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setAttribute("name", "ivan"); String jsp_url="/test.jsp"; String html_ulr=request.getRealPath("") + "//html//success.html"; CreateHTMLUtli.createHTML4Mapping(request, response, jsp_url, html_ulr); response.sendRedirect("html/success.html"); } }

四、在地址欄輸入 http://localhost:8080/項目名稱/CreateHTMLServlet ,

OK ,成功！
