鉴于现在还是有很多项目用xml形式来整合,所以又来整了一遍
上篇基于java config的链接 : http://www.jianshu.com/p/8fcefc4d724b

需要的环境与上一篇一致,其他相同的配置在这里也不再重写一遍了

new module,选择maven , Create From archetype,然后一路next,填写自己的包名

点击finish之后,idea会自动使用maven进行build,build后你会发现在src/main下没有java夹子

Paste_Image.png
新建一个java夹子,然后打开Project-Settings,使java夹子Mark as Sources,最后Apply,Ok.

以上就建立了一个空的module,最后的工程结构如下图所示

这里大致的结构与上一篇相似,明显不同的在于多了一个webapp,这里放了静态资源,views,spring配置以及web.xml
web.xml

ps : thymeleaf的staticVariables没有生效,如果有大牛看到,请在评论里给我答疑 ^_
