Spring cloudFeignClient send header programmatically in RequestInterceptor

i'm working on a spring boot project where i should call a rest api using Feign via Spring Cloud, i can call the rest api using feignClient without any problem, now the rest api that i call needs a JWT to let me consume it, to send a JWT from my code i used RequestInterceptor and this my code : 

class AuthInterceptor implements RequestInterceptor {

    @Override
    public void apply(RequestTemplate template) {
        template.header("Authorization", "Bearer eyJraWQiOiJOcTVZWmUwNF8tazZfR3RySDZkenBWbHhkY1uV_1wSxWPGZui-t1Zf2BkbqZ_h44RkjVtQquIe0Yz9efWS6QZQ");

    }

}

i put manually the JWT in the code and this work fine ...

my issue is : the JWT expire after 30 min and i should call manually another rest api that generate a JWT then i hardcode it in my code...

my question is : there any solution to call programmatically the api that generate JWT then inject this JWT in the Interceptor?

Thanks in advance.

Best Regards.

Get the Token from the current HttpServletRequest header.

public void apply(RequestTemplate template) {
    HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
            .getRequest();
    String jwtToken = request.getHeader(HttpHeaders.AUTHORIZATION);
    if (jwtToken != null) {
        template.header(HttpHeaders.AUTHORIZATION, jwtToken);
    }
}
