jaas - Wildfly 自定义登录模块错误

标签 jaas wildfly

我实现了一个通过 Web 服务访问的自定义 loginModule，并在 JPA 访问的 DB 前面检查用户名和密码。
我在 jboss 7.1 上运行它，它运行良好，但是在将它移动到 Wildfly(并添加我认为正确的配置)之后，我得到了一个来自 Wildfly 类内部的 NullPointerException。有任何想法吗？

这是我的自定义登录模块:

public class JPALoginModule implements LoginModule {

    CallbackHandler callbackHandler;
    Subject subject;
    Map sharedState;
    Map options;

    boolean success;

    @Override
    public void initialize(Subject subject, CallbackHandler callbackHandler,
        Map<String, ?> sharedState, Map<String, ?> options) {
        System.out.println("JPALoginModule.initialize()");
        this.callbackHandler = callbackHandler;
        this.subject = subject;
        this.sharedState = sharedState;
        this.options = options;
        InitialContext context = null;
        try {
            context = new InitialContext();
        } catch (NamingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        try {
            this.loginVerifier = (LoginVerifier) context.lookup("java:global/jaas.ear/jaas.ejb/LoginVerifierBean!beans.LoginVerifier");
        } catch (NamingException e) {

    @Override

        System.out.println("JPALoginModule.login()");
        try {

            Callback[] callbacks = new Callback[] {
                new NameCallback("Username: "),
                new PasswordCallback("Password: ", false) };

            callbackHandler.handle(callbacks);

            String username = ((NameCallback) callbacks[0]).getName();
            String password = new String(
                ((PasswordCallback) callbacks[1]).getPassword());

            success = loginVerifier.verify(username, password);

            if (!success) {

        catch (NullPointerException e) {
            System.out.println(e.getMessage()+" "+e.getLocalizedMessage());
        }
        return false;
    }

    @Override
    public boolean commit() throws LoginException {
        if (success) {
            if (subject.isReadOnly()) {
                throw new LoginException("subject is read only");
            }
            if (callbackHandler instanceof PassiveCallBackHandler) {
                ((PassiveCallBackHandler) callbackHandler).clearPassword();
            }
            return true;
        }
        else {
            return true;
        }
    }

    @Override
    public boolean abort() throws LoginException {
        logout();
        return true;
    }

    @Override

        if (callbackHandler instanceof PassiveCallBackHandler) {
            ((PassiveCallBackHandler) callbackHandler).clearPassword();
        }
        return true;
    }

         </authorization>
     </security-domain>
</security-domains>

最佳答案

好的，我找到了原因，这是因为我没有在身份验证后添加主体。

所以我添加了这个:

if (!success) {
    throw new LoginException(
        "Authentication Failed: Wrong Password");
} else if (success) {
    Principal passPrincipal = new UsernamePrincpal(username);
    subject.getPrincipals().add(passPrincipal);
    subject.getPrivateCredentials().add(password);
    return true;
}

它有效
