SpringMvc项目搭建(图文超详细)

一.首先准备一个tomcat-9的版本 和maven 和idea

二.打开iedea

1.创建maven项目和maven web模块(File-New-project)

 2.创建好maven项目之后设置maven路径(File--搜索Maven)

3.在maven项目里面创建maven web module

 修改web.xml 中的版本约束

<?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

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>4.0.1</version>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>4.0.1</version>
  <scope>compile</scope>
</dependency>

创建servlet

package com.msb.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;
/**

 * @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);
    }
}

准备一个first.jsp

配置Tomcat启动运行项目
添加运行的外部Tomcat环境
