【Mavan】初遇Spring春天：注意IDEA与Mavan的版本冲突

1.Mavan配置 2.1 Spring跑起来 2.2 Spring+Web

mavan的pom.xml中所配置spring框架的基本依赖。

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-context</artifactId>
  <version>4.0.2.RELEASE</version>
</dependency>
<dependency>
  <groupId>org.springframework</groupId>

• Unable to import maven project: See logs for detail
  why: IDEA与Mavan的版本不匹配
  solution: 用IDEA发行日期前的Mavan版本方可。IDEA2018.3.6用Mavan3.5.4没问题
  

• Failed to create a Maven project: ‘C:/Users/fei/Desktop/IdeaProjects/SpringDemo/pom.xml’ already exists in VFS
  why:之前我已经在这个文件夹里创建过同名的maven项目
  solution:先把这个项目删了，然后把回收站中的这个项目和之前同名的项目一起彻底删除

• application context not configured for this file
  why：起初在resources文件夹下新建了专门用于spring config文件.xml(但这个有小绿叶子哦)，但没有配置该文件到项目中
  solution:
  

或者
