2.3. 使用 Elytron 进行身份切换

SecurityDomain securityDomain = SecurityDomain.getCurrent();
Callable<T> forwardIdentityCallable = () -> {
    return AuthenticationContext.empty()
            .with(MatchRule.ALL,
                    AuthenticationConfiguration.empty()
                    .setSaslMechanismSelector(SaslMechanismSelector.ALL)
                    .useForwardedIdentity(securityDomain))
            .runCallable(callable);
};

securityDomain.authenticate(remoteUsername, new PasswordGuessEvidence(remotePassword.toCharArray())).runAs(forwardIdentityCallable);
