1.比如在a.properties中我们声明了一个变量:
classRoom=com.wc82.ClassRoom
2.然后在spring的配置文件中:applicationContext.xml，有如下的配置:
<bean id="classRoom" class="${classRoom}" />
这样的配置是不可以的，会报错:
Caused by: java.lang.ClassNotFoundException: ${classRoom}

但以下的配置是可以的:
<property name="calssoom" value="${classRoom}"></property>
spring中的class配置不能使用properties中的字符串
