spring中applicationContext.xml文件解析
Spring的applicationContext.xml文件
以下是详解Spring的applicationContext.xml文件代码：
<!-- 头文件，主要注意一下编码 -->
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- 建立数据源 -->
<bean id="dataSource" />
</property>
<!-- 配置映射文件 -->
<property name="mappingResources">
<list>
<value>com/alonely/vo/User.hbm.xml</value>
</list>
</property>
</bean>
<!-- 把Session工厂注入给hibernateTemplate -->
<!-- 解释一下hibernateTemplate：hibernateTemplate提供了很多方便的方法，在执行时自动建立 HibernateCallback 对象，例如：load()、get()、save、delete()等方法。 -->
<bean id="hibernateTemplate"
/>
</constructor-arg>
</bean>
<!-- 把DAO注入给Session工厂 -->
<bean id="userDAO" />
</property>
</bean>
<!-- 把Service注入给DAO -->
<bean id="userService" />
</property>
</bean>
<!-- 把Action注入给Service -->
<bean name="/user" />
</property>
</bean>
</beans>
