spring4 + mybatis3 + spring mvc + veloctiy + maven 整合

1，準備工作
spring4 jar 鏈接 https://spring.io/官網
http://maven.springframework.org/release 下載地址

mybatis3 鏈接 https://github.com/mybatis/mybatis-3
官網 mybatis.org 翻譯的語言有很多哦，有中文的。

日誌使用slf4j+logback

mysql 驅動下載 http://www.mysql.com/products/connector/

開發工具idea 下載地址http://www.jetbrains.com/idea/download/

2、通過maven命令創建 web項目
mvn archetype:create -DgroupId=com.cms -DartifactId=cms-web -DarchetypeArtifactId=maven-archetype-webapp

項目創建完成，但是項目結構還完全，需要在項目設置裏面創建完成，把測試junit3 改成4

maven創建的項目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-->
