Missing refresh_token

[itzfatoni]

i tried running this command

curl -X POST -u messaging-client:secret -d "client_id=messaging-client" -d "username=user1" -d "password=password" -d "grant_type=password" http://localhost:8080/oauth2/token

the response is look like this

{"access_token":"eyJraWQiOiJlOTI3MDY5ZC1iZWZiLTQwMTgtYTIxNi0wMGVhYTBkNThlYWIiLCJhbGciOiJSUzI1NiJ9.eyJzdWIiOiJ1c2VyMSIsImF1ZCI6Im1lc3NhZ2luZy1jbGllbnQiLCJuYmYiOjE3MTk3MzA3MTIsImlzcyI6Imh0dHA6Ly9sb2NhbGhvc3Q6ODA4MCIsImV4cCI6MTcxOTczMTAxMiwiaWF0IjoxNzE5NzMwNzEyLCJqdGkiOiJiZjJlOTY1ZS1lOTBjLTRkYmYtYTFkOS0zZDJmNTJlMzJmNWMiLCJhdXRob3JpdGllcyI6W119.rKPZU6WG8We_TxTO2ohVw7HKBdme98g3zpzlhCWrwxgrqMyCljM6taKPui8UxpmCzEawOupy2eHlUwh3rQ_sd6OgfzrzFozStcrJlrYYOoUPvG8rt4f5j6RwGI55s--cGqaY4OZ9LPUBIj3R3hyCa0txvKkM7ybptCoMtNL44JBQyakLD6ix3hPdnh4DcT_mHFe3oltFXUTWemyxBFHVZ4lnlGr2UThfwvRI_9pal-Ul-WyWFKGpFA-1-8Cof85AEjDBtR7uz-YcwyW8CLka8Wj-w05srfpMZTFMPy5vRNeJN96hZg5y9tDXX40Bxsaj6TwPMG2Nit3T8dV-O7Xe8A","token_type":"Bearer","expires_in":299}

the usual output of authorization server is look like this, how can I configure spring authorization server to return a refresh token?

i made it in this way

    override fun authenticate(auth: Authentication): Authentication {
        val authentication = auth as OAuth2PasswordGrantAuthenticationToken
        val principal = auth.principal as? OAuth2ClientAuthenticationToken ?: throw OAuth2AuthenticationException(OAuth2ErrorCodes.INVALID_CLIENT)
        if (authentication.grantType !in principal.registeredClient!!.authorizationGrantTypes) throw OAuth2AuthenticationException(OAuth2ErrorCodes.UNAUTHORIZED_CLIENT)
        val authenticationToken = UsernamePasswordAuthenticationToken(userDetailsService.loadUserByUsername(authentication.username), authentication.password, emptyList())
        authenticationConfiguration.authenticationManager.authenticate(authenticationToken)

        val builder = DefaultOAuth2TokenContext.builder()
            .registeredClient(principal.registeredClient)
            .principal(authenticationToken)
            .authorizationServerContext(AuthorizationServerContextHolder.getContext())
            .authorizationGrantType(AuthorizationGrantType.PASSWORD)
            .authorizationGrant(authentication)

        val accessToken = tokenGenerator.generate(builder.tokenType(OAuth2TokenType.ACCESS_TOKEN).build())!!
        val refreshToken = tokenGenerator.generate(builder.tokenType(OAuth2TokenType.REFRESH_TOKEN).build())!!
        return OAuth2AccessTokenAuthenticationToken(
            principal.registeredClient,
            principal,
            OAuth2AccessToken(OAuth2AccessToken.TokenType.BEARER, accessToken.tokenValue, accessToken.issuedAt, accessToken.expiresAt),
            OAuth2RefreshToken(refreshToken.tokenValue, refreshToken.issuedAt, refreshToken.expiresAt)
        )
    }
