Spring加载properties文件的两种方式

一：

 <context:property-placeholder location="classpath:conn.properties"/>


  <bean id="dataSource" class="${dataSource}">
     <property name="driverClass" value="${driverClass}" />
     <property name="jdbcUrl" value="${jdbcUrl}" />
     <property name="user" value="${user}" />
     <property name="password" value="${password}" />
  bean>

二：

 <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
     <property name="locations">
         <array>
             <value>classpath:conn.propertiesvalue>
         array>
     property>
 bean>
