英文:
KeyCloak getProvider() return null
问题
我的KeycloakSmsAuthenticatorUtil类有一个getMessage(AuthenticationFlowContext context, String key)方法，该方法使用themeProvider获取主题，但是keycloakSession.getProvider()方法总是返回null。
public class KeycloakSmsAuthenticatorUtil {
private static Logger logger = Logger.getLogger(KeycloakSmsAuthenticatorUtil.class);
...
public static String getMessage(AuthenticationFlowContext context, String key) {
String result = null;
try {
ThemeProvider themeProvider = context.getSession().getProvider(ThemeProvider.class, "extending");
if (themeProvider == null) {
logger.warn("THEME PROVIDER IS NULL");
}
Theme currentTheme = themeProvider.getTheme(context.getRealm().getLoginTheme(), Theme.Type.LOGIN);
Locale locale = context.getSession().getContext().resolveLocale(context.getUser());
result = currentTheme.getMessages(locale).getProperty(key);
} catch (IOException e) {
logger.warn(key + "not found in messages");
}
return result;
}
}
Themeprovider为null，因此当接收到currentTheme后，程序会在下一行崩溃。
.[0m.[33m16:43:40,550 警告 [six.six.keycloak.authenticator.KeycloakSmsAuthenticatorUtil] (default task-2) THEME PROVIDER IS NULL
.[0m.[33m16:43:40,551 警告 [org.keycloak.services] (default task-2) KC-SERVICES0013: 认证失败: java.lang.NullPointerException
在 deployment.keycloak-sms-authenticator-sns-test.jar//six.six.keycloak.authenticator.KeycloakSmsAuthenticatorUtil.getMessage(KeycloakSmsAuthenticatorUtil.java:173) 处发生
如何获得非空的themeProvider？
错误出现在ThemeProvider中，而不是上下文或keycloakSession中。
英文:
my KeycloakSmsAuthenticatorUtil class has a getMessage(AuthenticationFlowContext context, String key) method that uses the themeProvider to get the theme, but the keycloakSession.getProvider() always returns null.
public class KeycloakSmsAuthenticatorUtil {
private static Logger logger = Logger.getLogger(KeycloakSmsAuthenticatorUtil.class);
...
public static String getMessage(AuthenticationFlowContext context, String key) {
String result = null;
try {
ThemeProvider themeProvider = context.getSession().getProvider(ThemeProvider.class, "extending");
if (themeProvider == null) {
logger.warn("THEME PROVIDER IS NULL");
}
Theme currentTheme = themeProvider.getTheme(context.getRealm().getLoginTheme(), Theme.Type.LOGIN);
Locale locale = context.getSession().getContext().resolveLocale(context.getUser());
result = currentTheme.getMessages(locale).getProperty(key);
} catch (IOException e) {
logger.warn(key + "not found in messages");
}
return result;
}
Themeprovider is null, so the program crashes on the next line when the currentTheme is received.
.[0m.[33m16:43:40,550 WARN [six.six.keycloak.authenticator.KeycloakSmsAuthenticatorUtil] (default task-2) THEME PROVIDER IS NULL
.[0m.[33m16:43:40,551 WARN [org.keycloak.services] (default task-2) KC-SERVICES0013: Failed authentication: java.lang.NullPointerException
at deployment.keycloak-sms-authenticator-sns-test.jar//six.six.keycloak.authenticator.KeycloakSmsAuthenticatorUtil.getMessage(KeycloakSmsAuthenticatorUtil.java:173)
how can i get a non nullable themeProvider?
the error is in the ThemeProvider, not in the context or keycloakSession.

我使用了ThemeManager替换了ThemeProvider，这帮助了。
public static String getMessage(AuthenticationFlowContext context, String key) {
String result = null;
try {
KeycloakSession keycloakSession = context.getSession();
RealmModel realmModel = context.getRealm();
String loginTheme = realmModel.getLoginTheme();
ThemeManager themeManager = keycloakSession.theme();
Theme currentTheme = themeManager.getTheme(loginTheme, Theme.Type.LOGIN);
Locale locale =
context.getSession().getContext().resolveLocale(context.getUser());
result = currentTheme.getMessages(locale).getProperty(key);
} catch (IOException e) {
logger.warn(key + "在消息中未找到");
}
return result;
}
英文:
I replaced ThemeProvider with ThemeManager, it helped.
public static String getMessage(AuthenticationFlowContext context, String key) {
String result = null;
try {
KeycloakSession keycloakSession = context.getSession();
RealmModel realmModel = context.getRealm();
String loginTheme = realmModel.getLoginTheme();
ThemeManager themeManager = keycloakSession.theme();
Theme currentTheme = themeManager.getTheme(loginTheme, Theme.Type.LOGIN);
Locale locale =
context.getSession().getContext().resolveLocale(context.getUser());
result = currentTheme.getMessages(locale).getProperty(key);
} catch (IOException e) {
logger.warn(key + "not found in messages");
}
return result;
}
