编写Servlet

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class ServletTest1 extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        req.setCharacterEncoding("UTF-8");
        resp.setContentType("text/html;charset=utf-8");
        System.out.println("小鸟伏特加");
        resp.getWriter().write("小鸟伏特加(*￣︶￣)");
    }
}

编写配置文件web.xml

ersion="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <servlet>
        <servlet-name>test1</servlet-name>
        <servlet-class>com.min.ServletTest1</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>test1</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>
