cdi - 如何自定义 seam 3 凭据？

Question

有没有办法自定义接缝 3 凭据对象？

我需要向凭据（验证码）添加另一个属性。我尝试了以下代码：

@Named("credentials") @SessionScoped
public class Credentials extends CredentialsImpl {

    private static final long serialVersionUID = -4377742708407292709L;

    private String captcha;

    public String getCaptcha() {
        return captcha;
    }

    public void setCaptcha(String captcha) {
         this.captcha = captcha;
    }

}

但它与 org.jboss.seam.security.CredentialsImpl @Named 注解有冲突。如何覆盖凭据？

Answer 1

Yould 可以尝试CDI 专业化。IE ：

@Alternative 
@Specializes 
@SessionScoped
public class Credentials extends CredentialsImpl {

    private static final long serialVersionUID = -4377742708407292709L;

    private String captcha;

    public String getCaptcha() {
        return captcha;
    }

    public void setCaptcha(String captcha) {
         this.captcha = captcha;
    }

}
