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("
