IDEA 创建maven构建的spring mvc 项目 过程

一 创建java web项目

 

二. 添加spring mvc 框架支持

 

web.xml 内容如下；

 

 

再次运行，报如下错误

[2019-06-16 02:58:12,486] Artifact springmvc:war exploded: Artifact is being deployed, please wait...

编辑web.xml文件

再次运行，报如下错误

修改方法

 

 

注意右下角的apply与ok要点的

修改后再次运行

成功运行

接下来我们定义一个controller

建包 src.com.springmvc.controller 如下

 

在 src.com.springmvc.controller包下建类 indexController 如下

package com.springmvc.controller;

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

@Controller
@RequestMapping("/")
public class indexController {

    @RequestMapping("myIndex")
    public ModelAndView myIndex(){

        return new ModelAndView("myindex");
    }

}

 

在WEB-INF下建 jsp文件夹，并建文件myindex.jsp 如下

编辑 dispatcher-servlet.xml文件为如下内容

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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">
    <!-- 启用spring mvc 注解 -->
    <context:annotation-config />

    <!-- 设置使用注解的类所在的jar包 -->
    <context:component-scan base-package="com.springmvc.controller"></context:component-scan>


    <!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />

</beans>

修改web.xml文件

重新启动项目 并访问myIndex 如下

spring mvc配置成功

 

三.改为maven构建的项目，添加maven框架支持，把lib下面的包引用方式改为 maven的pom.xml方式管理

 

 

添加maven支持后项目目录会改变为如下层级

根据lib下引用包的列表，依次在pom.xml文件中找对应的包引用，注意版本要一致。并把lib下面的包删除

pom.xml引用部分内容

重启项目

报错

原因：改为pom.xml中引用后，包没有被发布到lib下面

修改方法

 

重新启动项目 并访问myIndex 截图如下

此时，jar包已通过pom.xml文件管理，maven框架添加成功

 

IDEA 下创建spring mvc项目并用maven构建 成功

先建java web项目，再添加spring mvc 和 maven的支持，感觉比先建maven项目要好理解一些
