Class AccessTokenResConverter

java.lang.Object

com.alpaca.security.oauth2.AccessTokenResConverter

All Implemented Interfaces:

org.springframework.core.convert.converter.Converter<Map<String,Object>,org.springframework.security.oauth2.core.endpoint.OAuth2AccessTokenResponse>

public class AccessTokenResConverter
extends Object
implements org.springframework.core.convert.converter.Converter<Map<String,Object>,org.springframework.security.oauth2.core.endpoint.OAuth2AccessTokenResponse>

Converter that transforms a raw token response Map into a structured OAuth2AccessTokenResponse.

This converter handles standard OAuth2 token response entries:

• access_token: required access token string.
• token_type: assigned as Bearer by default.
• expires_in: duration in seconds (parsed via Number.longValue()), with default fallback when missing.
• refresh_token: optional refresh token string.
• scope: parsed robustly from String or Collection inputs.

All other entries in the source map are treated as additional parameters and included in the result as an immutable read-only map. This approach offers flexibility for OAuth2 providers returning non-standard fields or when additional metadata is needed alongside the access token.
