Question

我有一个EJB来处理客户用户帐户的创建，这些客户帐户需要访问管理用户帐户的用户验证密钥的托管bean（帐户作用域）（密钥是临时的，因此它们不需要由数据库处理调用）。但是，我无法找到将验证密钥发送到EJB（生成发送给用户的验证电子邮件）的方法。

AccountVerifierBean.java

@ManagedBean(name = "accountVerifierBean", eager = true)
@ApplicationScoped
public class AccountVerifierBean implements Serializable {
    private HashMap<String, String> verificationKeyMapping;

    public AccountVerifierBean() {}

    public boolean verifyKey(String username, String key) {
        return key.equals(verificationKeyMapping.get(username));
    }
    public String generateKey(String username) {
        Date time = new Date();
        String key = username + time.toString();
        key = Encryption.hashSHA(key);
        verificationKeyMapping.put(username, key);
        return key;
    }
}

CustomerService.java

@Named
@Stateless
@LocalBean
public class CustomerService {
    @PersistenceContext(unitName = "MovieProject-ejbPU")
    private EntityManager em;

    private String username;
    private String password;

    //getters and setters

    public void validateEmail() {
        Properties serverConfig = new Properties();
        serverConfig.put("mail.smtp.host", "localhost");
        serverConfig.put("mail.smtp.auth", "true");
        serverConfig.put("mail.smtp.port", "25");

        try {
            Session session = Session.getInstance(serverConfig, new Authenticator() {
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication("<ACCOUNT>","<PASSWORD>");
                }
            });
            MimeMessage message = new MimeMessage( session );
            message.setFrom(new InternetAddress("accounts@minimalcomputers.com","VideoPile"));
            message.addRecipient(
                Message.RecipientType.TO, new InternetAddress(username)
            );
            message.setSubject("Welcome to VideoPile!");
            message.setContent("<p>Welcome to VideoPile, Please verify your email.</p><p>" + verifierKey + "</p>", "text/html; charset=utf-8"); //verifierKey is what I'm trying to get from AccountVerifierBean.
            Transport.send( message );
        }
        catch (MessagingException ex){
            Logger.getLogger(CustomerService.class.getName()).log(Level.SEVERE, null, ex);
        }
        catch (Exception e) {
            Logger.getLogger(CustomerService.class.getName()).log(Level.SEVERE, null, e);
        }
    }

    public String encrypt(String password) {
        try {
            return new     String(Base64.encode(MessageDigest.getInstance("SHA").digest(password.getBytes())));
        } catch (NoSuchAlgorithmException ex) {
            Logger.getLogger(CustomerService.class.getName()).log(Level.SEVERE, null, ex);
            return null;
        }
    }
}

我已尝试使用@Inject，@ ManagedProperty，使用应用程序映射，并使用ELContext。似乎没什么用。

修改我认为豆子有问题。从bean调用的任何方法似乎都没有做任何事情（EL已解析，但没有bean方法调用）。

我测试了它使用的注释（都是javax.faces.bean。*）

Answer 1

所以，问题出现在AccountVerifierBean中。

我在faces-config.xml中添加了以下行，现在它正在运行。

<managed-bean eager="true">
  <managed-bean-name>accountVerifierBean</managed-bean-name>
  <managed-bean-class>org.Videotheque.beans.AccountVerifierBean</managed-bean-class>
  <managed-bean-scope>application</managed-bean-scope>
</managed-bean>

我很确定问题是因为我的bean需要在EJB包而不是WAR中，以便EJB可以访问它，但正因如此，WAR并不知道bean存在。

从EJB访问ManagedBean方法
