内嵌tomcat快速入门

    1.依赖
        <!--Java语言操作tomcat -->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-core</artifactId>
            <version>8.5.16</version>
        </dependency>

        <!-- tomcat对jsp支持 -->
        <dependency>
            <groupId>org.apache.tomcat</groupId>
            <artifactId>tomcat-jasper</artifactId>
            <version>8.5.16</version>
        </dependency>
    2.新建一个IndexServlet 集成 HttpServlet，重写init,doGet,doPost
　　　　

/**
 * Project Name:mk-springboot <br>
 * Package Name:com.suns.servlet <br>
 *
 * @author mk <br>
 * Date:2019-3-14 17:04 <br>
 */

package com.suns.servlet;

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

/**
 * ClassName: IndexServlet <br>
 * Description:  <br>
 * @author mk
 * @Date 2019-3-14 17:04 <br>
 * @version
 */
public class IndexServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        this.doPost(req,resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        System.out.println(this.getClass()+" doPost");
        resp.getWriter().print("this is a embed tomcat");
    }

    @Override
    public void init() throws ServletException {
        System.out.println(this.getClass()+" init");
    }
}
