在配置文件中加入key,value

需要在spring配置文件注入   applicationContext.xml

<!-- 读取配置文件类 -->
<bean id="propertyFactory" class="com.creditease.autoloan.common.PropertyFactory">
  <constructor-arg>
     <list>
         <value>/config.properties</value>
         <value>/global.properties</value>
     </list>
  </constructor-arg>
</bean>

 

用的时候直接调用          PropertyFactory.getProperty("xxx");
