问题出现：引入一下代码，启动程序报错：The bean 'oauth2ClientFilterRegistration', defined in class path resource [org/springframework/boot/autoconfigure/security/oauth2/client/OAuth2RestOperationsConfiguration$SessionScopedConfiguration.class], could not be registered. A bean with that name has already been defined in com.hegret.SocialApplication and overriding is disabled.
@Bean

registration.setFilter(filter);
registration.setOrder(-100);
return registration;

Description:
The bean 'oauth2ClientFilterRegistration', defined in class path resource [org/springframework/boot/autoconfigure/security/oauth2/client/OAuth2RestOperationsConfiguration$SessionScopedConfiguration.class], could not be registered. A bean with that name has already been defined in com.hegret.SocialApplication and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
问题分析：跟踪源码，在OAuth2RestOperationsConfiguration类中已经定义过该bean对象了

解决方法：
在application.yml文件中添加配置，对bean进行重新定义覆盖
spring:
main:
allow-bean-definition-overriding: true重新启动，运行正常
