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
    public FilterRegistrationBean<OAuth2ClientContextFilter> oauth2ClientFilterRegistration(OAuth2ClientContextFilter filter) {
        FilterRegistrationBean<OAuth2ClientContextFilter> registration = new FilterRegistrationBean<OAuth2ClientContextFilter>();
        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
