运行结果及报错内容

@Autowired
private ToBrailleMsgInterface toBraille;
报错：
Description:

Field toBraille in tobraille1.controller.ToBraille required a bean of type 'tobraille1.service.serviceInterface.ToBrailleMsgInterface' that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'tobraille1.service.serviceInterface.ToBrailleMsgInterface' in your configuration.

看下service实现类有没有service注解

使用@Resource注解看看
