spring上下文在web.xml中的配置

/article/8597693.html

[java] view
plaincopy

<!-- Spring配置文件开始 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath*:com/avicit/resource/spring/spring-base.xml</param-value>

</context-param>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<!-- Spring配置文件结束 -->

对于

[java] view
plaincopy

org.springframework.web.context.ContextLoaderListener

可以参见
http://blog.csdn.net/seng3018/article/details/6758860 中的说明

一般spring上下文中xml默认叫applicationContext.xml

[java] view
plaincopy

<!-- 扫描注解Bean -->

<context:component-scan base-package="com.avicit">

<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>

</context:component-scan>

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="locations">

<list>

<value>classpath*:com/avicit/resource/jdbc/jdbc.properties</value>

<value>classpath*:com/avicit/resource/hibernate/hibernate.properties</value>

</list>

</property>

</bean>

<!-- 国际化的消息资源文件 -->

<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">

<property name="basenames">

<list>

<!-- 在web环境中一定要定位到classpath 否则默认到当前web应用下找 -->

<value>classpath:com/avicit/resource/message/messages</value>

</list>

</property>

<property name="defaultEncoding" value="UTF-8"/>

<property name="cacheSeconds" value="60"/>

</bean>

<import resource="classpath*:com/avicit/resource/spring/spring-dao.xml"/>

[java] view
plaincopy

<import resource="classpath*:com/avicit/resource/spring/spring-dao.xml"/>

这里导入了另一个配置文件，就是配置数据源的

[java] view
plaincopy
