如何从Servlet获取JSP页面的内容？

Question

I need to get the content of a jsp page from a servlet without redirect or forward, like a file for security issues, I'll process the HTML and write the new generated HTML in the servlet response. How can I do that?

An example of what I'm trying to do:

if (request.getParameter("pageName").equals("index")) {
    //get index.jsp content and process it...
}

You can't do that in a servlet, but you could do it in a Filter, in the doFilter method. You would need to provide a wrapper around the response object, something like what they do here .
