额...我们没用feign，所以没研究过，https://blog.csdn.net/u013360850/article/details/81813262 https://www.cnblogs.com/mxmbk/p/9883629.html 百度了两个帖子供参考。

import feign.RequestInterceptor;

import feign.RequestTemplate;

import lombok.extern.slf4j.Slf4j;

import org.springframework.security.core.Authentication;

import org.springframework.security.core.context.SecurityContext;

import org.springframework.security.core.context.SecurityContextHolder;

import org.springframework.security.oauth2.provider.authentication.OAuth2AuthenticationDetails;

import org.springframework.context.annotation.Configuration;

@Configuration

public class FeignOauth2RequestInterceptor implements RequestInterceptor {

    private final String AUTHORIZATION_HEADER = "Authorization";

    private final String BEARER_TOKEN_TYPE = "Bearer";

    @Override

    public void apply(RequestTemplate requestTemplate) {

        SecurityContext securityContext = SecurityContextHolder.getContext();

        Authentication authentication = securityContext.getAuthentication();

        if (authentication != null && authentication.getDetails() instanceof OAuth2AuthenticationDetails) {

            OAuth2AuthenticationDetails details = (OAuth2AuthenticationDetails) authentication.getDetails();

            requestTemplate.header(AUTHORIZATION_HEADER, String.format("%s %s", BEARER_TOKEN_TYPE, details.getTokenValue()));

        }

    }

}

亲测可用

  我为什么获取不到，authentication是null
