错误描述：
在旧项目的基础上，添加了新的功能，启动项目进行测试时，报如下错误????

错误分析：
提取主要错误提示

Annotation-specified bean name 'currentIssuesController' for bean class [com.vinux.controller.hospital.CurrentIssuesController] conflicts with existing, non-compatible bean definition of same name and class [com.vinux.controller.current.CurrentIssuesController]

错误提示很清楚，即存在两个currentIssuesController，以至出现了bean冲突（添加新功能时创建了一个 currentIssuesController 控制类，但项目中已经有了这样一个类）

解决办法：
将新建的 currentIssuesController 控制类换一个名字即可。
