我们可以使用jwtCustomizer添加任何信息。请参考this

@Bean
    OAuth2TokenCustomizer<JwtEncodingContext> jwtCustomizer(CustomClaims claims) {
        return context -> {
            if (context.getTokenType() == OAuth2TokenType.ACCESS_TOKEN) {
                Authentication principal = context.getPrincipal();
                Set<String> authorities = principal.getAuthorities().stream()
                        .map(GrantedAuthority::getAuthority)
                        .collect(Collectors.toSet());
                context.getClaims().claims(c -> c.put("Creator", "Thirumal"));
                context.getClaims().claims(c -> c.putAll(claims.getClaims(principal)));
                context.getClaims().claim("roles", authorities);
            }
        };
    }
