   @kevinw66 @kylixs 我今天在继续探索3.0的升级过程中, 又发现了个问题. 也和PropertySourcesPropertyResolver相关, 在原有的简易demo上引入了三方sdk, 比如aliyun-oss, 其中也有变量引入${aaa}, 如果采用
   `<bean id="propertiesUtil" class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer"></bena>`
   的方式不会报错, 但是采用自定义类集成PropertySourcesPlaceholderConfigurer,如:
   `<bean id="propertiesUtil" class="com.wqh.demo.dobbo3.PropertiesUtil">`
    又会引发上面的(Could not resolve placeholder)问题, 
    同样, 我把版本回到2.7.8  程序又能正常运行! 请原谅我三番五次的对比和折磨!  因为这对我的项目很重要!
    详情可以参考下面改进后的demo
