设置maven和 lombok
创建maven web module
注意选择骨架为maven-archetype-webapp
键入GroupID和 artfactid
补充项目结构文件夹并标记文件夹
创建好目录后,选中目录,右击 mark directory as 选择对应目录类型即可
修改web.xml 中的版本约束
可以创建一个javaEE项目,然后复制web.xml文件中的内容即可
<?xml version="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_4_0.xsd"
version="4.0">
</web-app>
创建普通Servlet,然后跳转至JSP
导入依赖
<!--servlet jsp 依赖-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.3.3</version>
<scope>provided</scope>
</dependency>
创建servlet
package com.lanson.controller;
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;
/**
* @Author: Lansonli
* @Description: MircoMessage:Mark_7001
*/
@WebServlet("/myServlet.do")
public class MyServlet extends HttpServlet {
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.getRequestDispatcher("first.jsp").forward(req,resp);
}
}
配置Tomcat启动运行项目
添加运行的外部Tomcat环境
将当前模块放入Tomcat
