Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

解决方法：

springboot启动报错如下：

Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

Disconnected from the target VM, address: '127.0.0.1:54176', transport: 'socket'

Process finished with exit code 1

因为sringboot通过@Autowired注入接口的实现类时发现有多个，也就是有多个类继承了这个接口，spring容器不知道使用哪一个。

第一种、加@Primary表示某个实现类首选注入：http://www.yayihouse.com/yayishuwu/chapter/2408
