Example 2 with AttributeMapper

use of org.forgerock.openam.authentication.modules.common.mapping.AttributeMapper in project OpenAM by OpenRock.

the class OAuth method getAttributesMap.

// Obtain the attributes configured for the module, by using the pluggable
// Attribute mapper
private Map<String, Set<String>> getAttributesMap(String svcProfileResponse, JwtClaimsSet jwtClaims) {
    Map<String, Set<String>> attributes = new HashMap<String, Set<String>>();
    Map<String, String> attributeMapperConfig = config.getAttributeMapperConfig();
    for (String attributeMapperClassname : config.getAttributeMappers()) {
        try {
            AttributeMapper attributeMapper = getConfiguredType(AttributeMapper.class, attributeMapperClassname);
            attributeMapper.init(OAuthParam.BUNDLE_NAME);
            attributes.putAll(getAttributes(svcProfileResponse, attributeMapperConfig, attributeMapper, jwtClaims));
        } catch (ClassCastException ex) {
            debug.error("Attribute Mapper is not actually an implementation of AttributeMapper.", ex);
        } catch (Exception ex) {
            OAuthUtil.debugError("OAuth.getUser: Problem when trying to get the Attribute Mapper", ex);
        }
    }
    OAuthUtil.debugMessage("OAuth.getUser: creating new user; attributes = " + attributes);
    return attributes;
