Intellij IDEA2019创建原生web项目并且实现Servlet

1、环境要求（这里不做下载安装步骤的说明）

1.java 1.8.0_81

2.IntelliJ IDEA 2019.2.1

3.Tomcat

2、打开idea2019并且创建项目

3、配置tomcat运行

4、编写Web.xml以及创建Servlet类

    
    
        test
        xuan.ServletTest
    
    
    
        test
        /xiaoxuan
    

package xuan;

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 ServletTest extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doPost(req, resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        //设置响应的字符集为UTF-8
        resp.setContentType("text/html;charset=UTF-8");
        resp.getWriter().println("测试Servlet页面");
    }
}

5、启动Tomcat并且访问映射的路径（这里的是/xiaoxuan）
