在Spring Boot中修改OAuth2ClientAuthenticationProcessingFilter

Question

我想修改Spring Boot 1.3.2中OAuth2ClientAuthenticationProcessingFilter配置创建的@EnableOAuth2Sso。据我所知，OAuth2ClientAuthenticationProcessingFilter类是在内部构造的，没有任何应用程序上下文连接。有没有办法做到这一点？

不确定这是最好的方法，但您可以使用BeanPostProcessor执行此操作：

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;
        }
    }
