TestMultiModuleTest 为父项目，其余为子模块
test-api 存放bean和service的接口，普通的maven模块，没有选择archetype
test-provider 存放dao和service接口的实现，spring和mybatis的配置文件，普通的maven模块，没有选择archetype。依赖于test-api模块，需要在该模块的pom.xml中添加
test-web 存放controller和springMVC的配置文件，选择archetype为maven-archetype-webapp。依赖于test-api，test-provider模块，需要在该模块的pom.xml中添加

总结

一开始test-provider和test-web两个模块都是webapp，两个模块的spring配置文件分开读取。test-provider读取spring，mybatis配置文件；test-web读取springMVC配置文件。但在test-provider中的spring的配置文件一直读取不到，classpath:和classpath*:都不行。部署的有两个webapp，分两个tomcat部署也不行，合并部署也不行。留个坑。

分开读取配置文件待解决

改成在test-web中的web.xml读取所有的配置文件classpath:application-.xml。
