BeanIsAbstractException错误解决

     今天开始学习joindesk，按照手册中的Joindesk Setup运行，启动服务器，就出现BeanIsAbstractException异常，异常代码如下：

 

org.springframework.beans.factory.BeanIsAbstractException: Error creating bean with name 'baseTxService': Bean

      搞了半天，还是通过debug，查看源代码后才知道错误原因，后来在baseTxService后面加上scope="prototype"才把问题解决。

      现在把正确代码写下，以供大家参考，希望能够帮助大家。
