## 问题： ##

### 往SpringCloud的注册中心里注册服务时启动SpringBoot项目抛出异常 ###

Description:
    
    The bean 'dataSource', defined in BeanDefinition defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class] and overriding is disabled.
    
    Action:
    
    Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
    
    
    Process finished with exit code 1

## 原因： ##

SpringBoot和SpringCloud的版本不兼容造成。

## 解决方案: ##

在配置文件application.yml中添加两行配置信息即可，配置如下：

main:
        allow-bean-definition-overriding: true #当遇到同样名字的时候，是否允许覆盖注册

再次启动服务，测试OK

我们发现user-service服务已经注册成功了

给我们一个微信勾搭的机会
