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

原因是因为 spring-boot版本和spring-clound版本对应不上
部分版本对应如下

spring-boot版本为2.2.5.RELEASE，所以对应的spring-clound版本为 Hoxton.SR1
