一共有两种调派方式,一个是include用于包含进来,一个是forward,是转发出去。
这时先测试包含的include方式。
Some.java:
package cc.openhome; import java.io.IOException; import java.io.*; import javax.servlet.RequestDispatcher; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class Some */ @WebServlet("/some.view") public class Some extends HttpServlet { private static final long serialVersionUID = 1L; /** * @see HttpServlet#HttpServlet() */ public Some() { super(); // TODO Auto-generated constructor stub } /** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub PrintWriter out = response.getWriter(); out.println("Some do one..."); RequestDispatcher dispatcher = request.getRequestDispatcher("other.view"); dispatcher.include(request, response); out.println("Some do tow..."); out.close(); } }
OtherServlet.java:
package cc.openhome; import java.io.IOException; import java.io.*; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class OtherServlet */ @WebServlet("/other.view") public class OtherServlet extends HttpServlet { private static final long serialVersionUID = 1L; /** * @see HttpServlet#HttpServlet() */ public OtherServlet() { super(); // TODO Auto-generated constructor stub } /** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub PrintWriter out = response.getWriter(); out.println("Other do one..."); } }
