出现这个异常，开始以为以为的是，bean没有注册到，弄了半天，最后发现了问题所在，一般情况下我们使用Spring 的全家桶，都会在Spring 上下文配置文件去配置自动扫描类，并且用bean标签实现注册，当程序启动的时候就会注册生产一个bean。

但是呢，还有一个方法也是可以注册bean的，那就是Spring的注解@Autowire以及java的@Resouce注解，这个时候会导致重复注册bean了，1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 这个的意思就是bean的类型重复，除非你定义别的类型名称，

自动扫描bean的时候，检查是否多个配置文件都有<context:component-scan base-package=“****”/> 这个标签，如果有的话会导致重复注册的异常。一般只要核心配置文件去进行扫描类注册就可以了。

如果要实现多个bean的话，就按照名称来进行注解@Autowire配合@Qualifier(“beanName”)
