楼主解决了吗~

重写 ModularRealmAuthenticator 的 doMultiRealmAuthentication 方法
@Override
protected AuthenticationInfo doMultiRealmAuthentication(Collection<Realm> realms,
AuthenticationToken token) throws AuthenticationException {
AuthenticationStrategy strategy = getAuthenticationStrategy();
AuthenticationInfo aggregate = strategy.beforeAllAttempts(realms, token);
if (log.isTraceEnabled()) {
log.trace("Iterating through {} realms for PAM authentication", realms.size());
}
AuthenticationException authenticationException = null;
for (Realm realm : realms) {
aggregate = strategy.beforeAttempt(realm, token, aggregate);
if (realm.supports(token)) {
log.trace("Attempting to authenticate token [{}] using realm [{}]", token, realm);
AuthenticationInfo info = null;
try {
info = realm.getAuthenticationInfo(token);
} catch (AuthenticationException e) {
authenticationException = e;
if (log.isDebugEnabled()) {
String msg = "Realm [" + realm + "] threw an exception during a multi-realm authentication attempt:";
log.debug(msg, e);
}
}
aggregate = strategy.afterAttempt(realm, token, info, aggregate, authenticationException);
} else {
log.debug("Realm [{}] does not support token {}. Skipping realm.", realm, token);
}
}
if(authenticationException != null){
throw authenticationException;
}
aggregate = strategy.afterAllAttempts(token, aggregate);
return aggregate;
}
