idea-创建maven javaweb springmvc项目

一、创建项目

二、引入springmvc

三、配置web.xml、pom.xml

四、配置springmvc核心配置文件springmvc-config.xml

五、例子:需求

六、创建Controller类

七、创建jsp文件

八、添加tomcat服务器

九、运行

版本：

一、创建项目

创建完成后的文件目录：

完善目录：

完善后的目录：

二、引入springmvc

三、配置web.xml、pom.xml

1、pom.xml中加入jar包依赖

<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>

<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency>

2、web.xml文件中配置DispatcherServlet、springmvc核心配置文件springmvc-config.xml的路径

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
<display-name>Archetype Created Web Application</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>

<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

四、配置springmvc核心配置文件springmvc-config.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:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

<mvc:default-servlet-handler/>

<mvc:annotation-driven></mvc:annotation-driven>

<!--
3、配置包扫描：
在com.qxzh.controller包下提供Controller类
并且在Controller类上加上一个@Controller注解

spring容器会到指定的包下扫描包含@Controller注解的类
将这些类的对象的创建交给spring容器
-->
<context:component-scan base-package="com.qxzh.controller">
</context:component-scan>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">


<property name="prefix" value="/WEB-INF/pages/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>

五、例子:需求

1、通过浏览器访问http://localhost:8080/hello地址，在控制台输出“Hello”

2、将请求转向/WEB-INF/pages/home.jsp

六、创建Controller类

package com.qxzh.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller//表名是controller层、使得容器扫描到该类并创建该类的实例
public class HelloController {
    //访问路径：http://localhost:8080/hello
    @RequestMapping("/hello")//映射
    public String demo(){
        System.out.println("Hello");
        //路径：/WEB-INF/pages/home.jsp
        return "home";
    }
}

七、创建jsp文件
