先新建一个maven的项目
1.file->new->project->next
2.maven->勾选creat from archetype->webapp,同时选择java版本->next
3.输入GroupID,ArtifacID
(在网上看到的一些解释:groupId：定义了项目属于哪个组，一般来说这个通常和公司或组织关联，比如说，你所在的公司为wk.那就应该定义为com.wk.wktest，wktest为项目名称
artifactId：定 义了当前Maven项目在组中的唯一id，例如wktest这个项目，我则把他定义为test1，还例如spring项目，他的 groupId为org.springframework，对于content项目来说artifactId则为spring-content，web项 目则为spring-web)
点击next
4.选择idea自带的maven或者本地安装好的maven，next
6.默认，不需要改 next
7.点击finish，然后项目构建结束后，点击import changes
8.检测是否成功，控制台打印Build success 说明成功
搭建ssm环境。
1结构搭建
在src下新建test文件夹，和main同级，
选中test，右键-》mark directory as-》test sources root，意思是把test设置为测试类的根目录
在main下新建文件夹resource 和web，右键-》mark directory as
将resource设置为 resources root（资源文件根目录）
将web设置为sources root（文件根目录）
在resource下新建xml文件，用来写sql
在web下新建wk，在wk下新建controller，service，serviceImpl，dao文件夹，再分别建立对应的java文件
在resource下添加配置文件applicationContext.xml，spring-mvc.xml，spring-mybatis.xml，config.properties，log4j.properties
配置pom文件 ，在<properties>节点里添加
