一、安装java环境（略）
这方面资料很多
我的环境是JDK6+eclipse4 j2ee版，自带Maven等一些插件
二、安装Maven（略）
Maven安装简单装好后修改 根目录/conf/settings.xml，配置好maven库目录
打开eclipse windows-preference-maven-userSettings-global settings选择maven安装目录的settings.xml文件
点击maven在主配置上勾选，这时maven会下载index可能会很慢。需要等等
三、创建maven工程
点击Eclipse菜单栏File->New->Ohter->Maven->选择项目目录->next->选择项目类型
搜索web，创建项目->next
填写groupId和artifact Id->finish
项目配置
右击项目－new
创建如下几个文件
配置build path
分别修改输出路径为
src/main/resources 对应 target/classes
src/main/java 对应 target/classes
src/test/resources 对应 target/test-classes
src/test/java 对应 target/test-classes
设置JDK版本
设置部署程序集(Web Deployment Assembly)
把两个test目录去掉！！！
到此项目算是部署完成了。如果有其他问题百度一下吧！！
三 spring mvc+spring+mybatis配置
首先pom.xml文件内容
