从servlet返回HTML / XHTML文件 [英] Returning an HTML/XHTML file from servlet
问题描述
我见过servlets示例，它们是这样的：
I've seen servlets examples, they're something like this:
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">");
...
}
我的问题是，而不是代码，我可以返回HTML页面吗？我的意思是，像这样：
My question is, instead of the code, can I return an HTML page? I mean, something like this:
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
SHOW(FILE.HTML);
}
谢谢！ ;）
推荐答案
有几种不同的方法可以做到这一点：
There are a few different ways you could do this:
-
将servlet转发到HTML文件所在的路径。类似于：
Forward the servlet to the path where the HTML file is located. Something like:
RequestDispatcher rd = request.getRequestDispatcher（something.html）;
rd.forward（请求，响应）;
将重定向发送到HTML所在的URL。类似于：
Send a redirect to the URL where the HTML is located. Something like:
response.sendRedirect（something.html）;
读入HTML文件的内容，然后将HTML文件的内容写出到servlet的PrintWriter。
Read in the contents of the HTML file and then write out the contents of the HTML file to the servlet's PrintWriter.
