1创建空项目 项目和maven web模块

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

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>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.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;
    /**
     * @Author: Ma HaiYang
     * @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(略)

配置Tomcat启动运行项目

添加运行的外部Tomcat环境

![685ace27fe62285df1a5caf9820491a7.png][]

将当前模块放入Tomcat

            <scope>provided</scope>
          </dependency>
        </dependencies>

3在web.xml中配置DispatcherServlet

<?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">
        
        <servlet>
            <servlet-name>dispatcherServlet</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            
            
           
            <load-on-startup>1</load-on-startup>
        </servlet>
        
        <servlet-mapping>
            <servlet-name>dispatcherServlet</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    </web-app>

4加入SpringMVC的配置文件

在resources下添加 springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:p="http://www.springframework.org/schema/p"
           xmlns:c="http://www.springframework.org/schema/c"
           xmlns:util="http://www.springframework.org/schema/util"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:aop="http://www.springframework.org/schema/aop"
           xmlns:tx="http://www.springframework.org/schema/tx"
           xsi:schemaLocation="
           http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/util
           http://www.springframework.org/schema/util/spring-util.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx.xsd
    ">
        
        <context:component-scan base-package="com.msb"></context:component-scan>
        
    </beans>

添加log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
    <Configuration status="DEBUG">
        <Appenders>
            <Console name="Console" target="SYSTEM_OUT">
                <PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
            </Console>
        </Appenders>
        <Loggers>
            <Root level="debug">
                <AppenderRef ref="Console" />
            </Root>
        </Loggers>
    </Configuration>

5编写controller层处理器

package com.msb.controller;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    /**
     * @Author: Ma HaiYang
     * @Description: MircoMessage:Mark_7001
     */
    @Controller
    @RequestMapping("/msb")
    public class FirstController  {
        @RequestMapping("/firstController.do")
        public String firstController(){
            System.out.println("this is firstController");
            return "/first.jsp";
        }
    }

6编写视图层
