建立一个maven-webapp项目:Create New Project

后点击next

然后next

可以选择默认自带的maven,还可以修改配置默认的maven的仓库地址使加快下载速度, 或者本地安装的apache-maven-3.5.2。

然后next

然后finish.

添加pom依赖
创建好之后的项目目录如图所示

打开pom.xml,添加依赖

建立相应的目录

项目创建完成后,src-main下建立java目录后,是无法在该目录下创建新的包和java类等文件的。在idea中需要对目录进行标注。

File->Project Structure:

现在还没有创建对应的目录,然后创建目录后,选择对应的标注:

标注完后,建立如下的目录。

配置web.xml

如果用maven自动生成的web.xml,可能读取不到springmvc返回传入的参数值,应该要修改web.xml

直接在原来的文件上面修改:


<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <display-name>Archetype Created Web Application</display-name>

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

注意要替换原来文件web-app的属性

启动时也会默认在/WEB-INF目录下查找XXX-servlet.xml作为配置文件,XXX就是DispatcherServlet的名字,也可以手动配置路径,现在使用默认的方式,

在WEB-INF目录下面创建mvc-dispatcher-servlet.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/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd  ">

    <context:component-scan base-package="com.xuan.springmvc.controller"/>
    <mvc:annotation-driven/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

添加views目录: 把index.jsp拖到此目录下面:

image

编辑代码路径/src/main/java,添加com.frank.springmvc.controller包,增加MainController.java:

package com.frank.springmvc.controller;

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

@Controller
public class MainController {

    @RequestMapping(value = "/index")
    public String index() {
        return "index";
    }
}

配置tomcat服务

Configure...配置tomcat路径

绿色+号,把项目加到部署列表

输入服务器名称和选择tomcat版本。

注意要选择第二项:

最后启动tomcat服务运行调试,显示结果:
