在src上右键，新创建servlet类
package com.howdy;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;周末祝福信息
@WebServlet(name = "RegServlet")
public class RegServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=utf-8");
PrintWriter out =Writer();
String Parameter("uname");
String Parameter("email");
String Parameter("mobile");
out.println("<html>");
璀璨人生好看吗out.println("<body>");
难道爱上你是一个错out.println("<h3>您的名字是:"+uname+" </h3>");
out.println("<h3>您的email是:"+email+" </h3>");
out.println("<h3>您的电话是:"+mobile+" </h3>");
out.println("</body>");
out.println("</html>");
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { }
}
在web中的l添加如下配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="/xml/ns/javaee"
xmlns:xsi="/2001/XMLSchema-instance"
xsi:schemaLocation="/xml/ns/javaee /xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<servlet>
<servlet-name>RegServlet</servlet-name>
<servlet-class>com.howdy.RegServlet</servlet-class>庆余年人物详细介绍
</servlet>
<servlet-mapping>
<servlet-name>RegServlet</servlet-name>
<url-pattern>/RegServlet</url-pattern>
</servlet-mapping>
<!-- <servlet-mapping>-->
西方世界的劫难<!-- <servlet-name>RegServlet</servlet-name>-->
<!-- <url-pattern>/mypro/RegServlet</url-pattern>-->
<!-- </servlet-mapping>-->
</web-app>
注意此地⽅是两种写法：
<url-pattern>/mypro/RegServlet</url-pattern> --->form的action应该是mypro/RegServlet
<url-pattern>/RegServlet</url-pattern> --->form的action应该是RegServlet
运⾏项⽬时，单击edit configuration
