搭建web服务器并实现简单的服务器接口

 1.给Eclipse配置Tomcat。

打开Eclipse 点击window->preferences->Server->Runtime Environments。如下图

 

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

点击Add

点击Next

打开控制台，选择Servers ，双击Tomcat v7.0 Server at locatlhost，修改参数

 

 

然后点击Start。那么Tomcat就部署好了。

接下来是创建Web项目。File -> new ->Other->Web ->Dynamic Web Project 

建好之后的项目目录是这样的。因为我的IDE是Eclipse所以我的目录结构中是WebContent;

 

在Src里面创建一个Servlet文件。

package test;

import java.io.IOException;
import java.io.PrintWriter;

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 TestServlet
 */
@WebServlet("/test")
public class TestServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public TestServlet() {
        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
        response.setContentType("text/html;charest=UTF-8");
        PrintWriter out = response.getWriter();
        try{
            out.println("<html>");
               out.println("<head>");
                 out.println("<title>HelloWorld</title>");
                 out.println("</head>");
                 out.println("<body>");
                 out.println("<h2>HelloWorld</h2>");
                 out.println("</body>");
                 out.println("</html>");
        }
        finally{
            out.close();
        }
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
    }

}

把项目加入Tomcat.右击Tomcat 服务器。点击Add and Remove 添加进去。

 

然后

 

 打开浏览器输入：http://localhost:8080/WebTest/test。其中WebTest是项目名，test 是TestServlet中 @WebServlet("/test")；
