Returning an HTML/XHTML file from servlet
提问by dak
I've seen servlets examples, they're something like this:
我看过 servlets 的例子，它们是这样的：
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\">");
...
}
My question is, instead of the code, can I return an HTML page? I mean, something like this:
我的问题是，我可以返回 HTML 页面而不是代码吗？我的意思是，像这样：
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
SHOW(FILE.HTML);
}
Thanks!!! ;)
谢谢！！！;)

There are a few different ways you could do this:
有几种不同的方法可以做到这一点：
Forward the servlet to the path where the HTML file is located. Something like:
RequestDispatcher rd = request.getRequestDispatcher("something.html"); rd.forward(request, response);Send a redirect to the URL where the HTML is located. Something like:
response.sendRedirect("something.html");Read in the contents of the HTML file and then write out the contents of the HTML file to the servlet's PrintWriter.
将 servlet 转发到 HTML 文件所在的路径。就像是：
RequestDispatcher rd = request.getRequestDispatcher("something.html"); rd.forward(request, response);将重定向发送到 HTML 所在的 URL。就像是：
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。
