将jsp页面转换成静态页面的步骤:
1、在jsp页面中加入servlet.代码如下:
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文件名,如index,不包括扩展名
// 则你访问这个servlet时加参数.如http://localhost/test/toHtml?file_name=index
url = "/" + file_name + ".jsf";// 你要生成的页面的文件名。我的扩展名为jsf .
name = ConfConstants.CONTEXT_PATH+"\\"+ file_name + ".htm";// 这是生成的html文件名,如index.htm.文件名字与源文件名相同。扩展名为htm
//ConfConstants.CONTEXT_PATH为你的应用的上下文路径。
RequestDispatcher rd = sc.getRequestDispatcher(url);
final ByteArrayOutputStream ōs = 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 ōut = response.getWriter();
out
.print("<p align=center><font size=3 color=red>页面已经成功生成!single<br>http://www.agilejava.org/space/? 233</font></p>");
}
}
2、配置web.xml
<servlet>
<servlet-name>toHtml</servlet-name>
<servlet-class>mj.util.html.ToHtml</servlet-class>//你的servlet的类。
</servlet>
<servlet-mapping>
<servlet-name>toHtml</servlet-name>
<url-pattern>/toHtml</url-pattern>
</servlet-mapping>
3、运行servlet。如:http://localhost:8080/test/toHtml?file_name=index
在test项目的根目录下,生成了一个index.htm的静态文件。

pw.println(info);

} catch (Exception ex) {
System.out.println(ex.getMessage());
}finally{

}
}
// 测试方法:
public static void main(String[] args) {
writeHtml(filePath,getHtmlCode(url,),flag);
}
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>这句话即可,但是要把扩展名改成html,如果出现乱码, 修改一下编码就好了
