This is the fifth day of my participation in the November Gwen Challenge. Check out the details: The last Gwen Challenge 2021

Four servers

Full check after Internet information service has interface binding change port (if required)

Web site (Static Page) System (dynamic site)

Netstate-ano Displays information about ports in the current system

preface

Servelet is a class that runs in Tomcat.

Create dynamic project server //eclipse in web (Javaee) view

Any class that inherits httpServlet is a servlet

Servlets must be in Tomcat to make sense (to run) and only in Tomcat Classfish WebLogic server servlet containers where websphere can run servlets

Start the Servlet container = Start Tomcat

Your servlet must be in the web-INF /classes directory with the compiled source file bytecode

IDEA to realize the running of IIS server

1. Create an empty project

2. Create a module

3. Create your own Servlet

Write your own business logic

5. Override the service method. Receive requests from the front desk

In the blank, press the keyboard shortcut ALT+INSERTCopy the code

6. Fill in your own business logic code

package com.hbwl.web01; import javax.servlet.*; import javax.servlet.http.*; import javax.servlet.annotation.*; import java.io.IOException; @WebServlet(name = "OkServlet", Value = "/OkServlet") public class OkServlet extends HttpServlet {//ALT+INSERT // change protected to public public void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {// Add your own business code system.out.println (" I am OkServlet"); }}Copy the code

7. Check project artifacts

See if project artifacts exist

An artifact is the resulting projectCopy the code

8. Configure the idea-Tomcat association

Select Tomcat on your local computer. If Tomcat is not available on your computer, download it from Tomcat.apache.org. Tomcat version 9 is usedCopy the code

9. Start Tomcat and test it

10. Test whether the Servlet can be accessed in the browser

View the open address of the Servlet you createdCopy the code

Enter in your browser: http://localhost:80/OkServletCopy the code
