java – 在servlet中包含jsp的内容

导读：我有这个servlet： public class SaveImage extends HttpServlet { protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException { PrintWriter out = null; try { out = response.getWriter(); ou

我有这个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();
        }
    }
}

这样做是否有问题(响应已经提交？),我该怎么做？

解决方法

request.getRequestDispatcher("/WEB-INF/my.jsp").include(request,response);

但你不应该像这样输出html的servlet.只需使用jsp,其中包含< jsp：include />或<％@ include file =“..”％>
