在 servlet 中包含 jsp 的内容 [英] Include the content of a jsp in a servlet
本文介绍了在 servlet 中包含 jsp 的内容的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
I have this servlet:
public class SaveImage extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = null;
try {
out = response.getWriter();
out.println("<html>");
...
// I want to include here the content of this jsp:
// /WEB-INF/mybox.jsp
// (also, with the full context of the servlet)
...
out.println("</html>");
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Is there a problem doing it (response already committed?), how can I do this?
解决方案
request.getRequestDispatcher("/WEB-INF/my.jsp").include(request, response);
But you should not a servlet for outputting html like that. Just use a jsp, with either <jsp:include /> or <%@ include file=".." %>
