在Spring Boot中修改OAuth2ClientAuthenticationProcessingFilter

Question

我想修改Spring Boot 1.3.2中由@EnableOAuth2Sso配置創建的OAuth2ClientAuthenticationProcessingFilter。據我所知，OAuth2ClientAuthenticationProcessingFilter類是內部構建的，沒有任何應用程序上下文連線。有沒有辦法做到這一點？

不知道這是做的最好的方式，但你可以用了BeanPostProcessor做到這一點：

public static class DefaultRolesPrefixPostProcessor implements BeanPostProcessor, PriorityOrdered { 

     @Override 
     public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException { 
      if (bean instanceof FilterChainProxy) { 

       FilterChainProxy chains = (FilterChainProxy) bean; 

       for (SecurityFilterChain chain : chains.getFilterChains()) { 
        for (Filter filter : chain.getFilters()) { 
         if (filter instanceof OAuth2ClientAuthenticationProcessingFilter) { 
          OAuth2ClientAuthenticationProcessingFilter oAuth2ClientAuthenticationProcessingFilter = (OAuth2ClientAuthenticationProcessingFilter) filter; 
          oAuth2ClientAuthenticationProcessingFilter 
            .setAuthenticationSuccessHandler(authenticationSuccessHandler()); 
         } 
        } 
       } 
      } 
      return bean; 
     } 
    }
