以下是一個簡單的servlet程序,首先見立一個目錄,在D:\Tomcat\webapps\下建立servletdemo,并添加一個子目錄WEB-INF文件夾import java.io.*;import javax.servlet.*;import javax.servlet.http.*;public class HelloWorld extends HttpServlet {? public void doGet(HttpServletRequest req, HttpServletResponse res)?????????????????????????????? throws ServletException, IOException {??? res.setContentType("text/html");??? PrintWriter out = res.getWriter();??? out.println("<HTML>");??? out.println("<HEAD><TITLE>Hello World</TITLE></HEAD>");??? out.println("<BODY>");??? out.println("<BIG>Hello World</BIG>");??? out.println("</BODY></HTML>");? }?public void doPost(HttpServletRequest req, HttpServletResponse res)????????????????????????????? throws ServletException, IOException? {???????????????????????? doGet(req, res);? }}在寫一個部署的文件web.xml<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app??? PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"??? " <web-app>??? <servlet>??????? <servlet-name>??????????? HelloWorld??????? </servlet-name>??????? <servlet-class>??????????? HelloWorld??????? </servlet-class>??? </servlet>??? <!--部署的第一種方式-->??? <servlet-mapping>??????? <servlet-name>??????????? HelloWorld??????? </servlet-name>??????? <url-pattern>??????????? /HelloWorld??????? </url-pattern>??? </servlet-mapping>?? <!--方式2--> ??? <servlet-mapping>??????? <servlet-name>??????????? HelloWorld??????? </servlet-name>??????? <url-pattern>??????????? /HelloWorld.do??????? </url-pattern>??? </servlet-mapping>???? <!--方式3-->? ???? <servlet-mapping>??????? <servlet-name>??????????? HelloWorld??????? </servlet-name>??????? <url-pattern>?????????? *.hello??????? </url-pattern>??? </servlet-mapping>???? <!--方式4-->? ???? <servlet-mapping>??????? <servlet-name>??????????? HelloWorld??????? </servlet-name>??????? <url-pattern>????????? /hello/*??????? </url-pattern>??? </servlet-mapping></web-app>這樣你就可以在瀏覽器中用以下url打開http://localhost:8080/servletdemo/HelloWorld/servletdemo/HelloWorld/hello.html/well.hello/fancy/meeting/you/here.hello/hello/to/you posted on 2006-08-12 10:32 fly 閱讀(5601) 評論(0) 編輯 收藏 所屬分類: jsp學習
