spring4 + mybatis3 + spring mvc + veloctiy + maven 整合

1，准备工作
spring4 jar 链接 https://spring.io/官网
http://maven.springframework.org/release 下载地址

mybatis3 链接 https://github.com/mybatis/mybatis-3
官网 mybatis.org 翻译的语言有很多哦，有中文的。

日志使用slf4j+logback

mysql 驱动下载 http://www.mysql.com/products/connector/

开发工具idea 下载地址http://www.jetbrains.com/idea/download/

2、通过maven命令创建 web项目
mvn archetype:create -DgroupId=com.cms -DartifactId=cms-web -DarchetypeArtifactId=maven-archetype-webapp

项目创建完成，但是项目结构还完全，需要在项目设置里面创建完成，把测试junit3 改成4

maven创建的项目web.xml 是2.5版本的
修改成3.0

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0"
         metadata-complete="true">
  <display-name>Archetype Created Web Application</display-name>
</web-app>

<-- 配置web.xml 文件-->
