使用Maven构建Spring MVC项目的简单示例
1、首先看一下项目结构：
总结：主要是将配置文件配置好之后就不会有什么问题了。在阅读《Maven实战》这本书的时候可以知道有一章是讲解关于继承和聚合的知识，这里主要的是Maven构建SpringMVC项目，所以DAO等这些都写到一起了。因为我也没有只用Maven进行过一个完整项目的实践，所以独立模块开发+聚合可以参考《Maven实战》这本书上面的示例讲解。作为初学者，有很多的东西要学。

3、applicationContext.xml配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <mvc:annotation-driven /> <context:component-scan base-package="com.tan.*" /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
