Spring oauth2 refresh token - Cannot convert access token to JSON

  \"access_t         


        

Answer 1

Also has same issue with Spring Boot 1.5.4

It is really actual that jwtAccessTokenConverter.setVerifierKey(publicKey);doesn't really set verifier(in debug value is null) that is used in -

JwtAccessTokenConverter
...protected Map decode(String token) {
        try {
            Jwt jwt = JwtHelper.decodeAndVerify(token, verifier);

as workaround helped:

private JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter jwtAccessTokenConverter = new CustomTokenEnhancer();
        jwtAccessTokenConverter.setSigningKey(jwtSigningKey);
        jwtAccessTokenConverter.setVerifier(new RsaVerifier(jwtPublicKey));
        log.info("Set JWT signing key to: {}", jwtAccessTokenConverter.getKey());

        return jwtAccessTokenConverter;
    }
