    \`
    
        import javax.servlet.http.HttpServlet;
        import javax.servlet.http.HttpServletRequest;
        import javax.servlet.http.HttpServletResponse;
        
        /**
         * @author ZhouYanXiang
         */
        public class Servlet1 extends HttpServlet {
              
            @Override
            protected void doGet(HttpServletRequest request, HttpServletResponse response) {
              
                System.out.println("----调用doGet()方法----");
            }
        
            @Override
            protected void doPost(HttpServletRequest request, HttpServletResponse response) {
              
                System.out.println("----调用doPost()方法----");
                //调用doGet方法
                doGet(request,response);
            }
        }
    
    \`
2.  ##### 在web.xml文件中配置 #####

    <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_4_0.xsd"
             version="4.0">
        <servlet>
            <servlet-name>Servlet1</servlet-name>
            <servlet-class>Servlet1</servlet-class>
        </servlet>
        <servlet-mapping>
            <servlet-name>Servlet1</servlet-name>
            <url-pattern>/Servlet1</url-pattern>
        </servlet-mapping>
