maven构建spring mvc项目 + Mybatis整合

一、新建项目

1、File>New>Other>Maven>Maven Project, 点击Next

 


2、选择项目保存路径。然后点击Next。
 


3、选择项目类型，在Artifact Id中选择maven-archetype-webapp，然后点击Next。
 


4、Group ID一般写大项目名称。Artifact ID是子项目名称。
例如Spring的web包，Group ID：org.springframework，artifactId：spring-web。
Package是默认给你建一个包，不写也可以。
填完后，点击Finish。

5、建好后的项目结构如下：

 
6、打开cmd命令窗口，cd到项目的跟目录。执行以下语句：
mvn clean eclipse:eclipse

注：
mvn clean     //清理（删除target目录下编译内容）

mvn eclipse:eclipse   //生成Eclipse项目结构

7、选中项目，右击：New>Other>java>Source Folder，点击Next
 


8、以下Floder Name必须为src/main/java
 


9、现目录结构如下：
 




二、配置文件设置（附部分配置说明）
1、pom.xml
