applicationContext.xml读取properties中属性

载入方式一：

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:jee="http://www.springframework.org/schema/jee"xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/jee
http://www.springframework.org/schema/jee/spring-jee-3.0.xsd">
<context:property-placeholderlocation="classpath:uc.properties"/>
</beans>

载入方式二：

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:jee="http://www.springframework.org/schema/jee"xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/jee
http://www.springframework.org/schema/jee/spring-jee-3.0.xsd">
<beanid="configBean"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<propertyname="locations">
<value>uc.properties</value>
</property>
</bean>
</beans>

使用方式：

<value>${name}</value>
或者
<propertyname="driverClass"value="${driverClass}"/>

如果有多个properties文件的情况

<beanid="configBean"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<propertyname="locations">
<list>
<value>hello.properties</value>
<value>welcome.properties</value>
<value>other.properties</value>
</list>
</property>
</bean>
