如何自定義seam 3憑證？

Question

有什麼方法可以自定義seam 3憑證對象嗎？

我需要添加一個更多的屬性憑據（captcha）。我tryed下面的代碼：

@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; 
    } 

} 

但它與org.jboss.seam.security.CredentialsImpl @Named標註的衝突。我如何覆蓋憑據？

Answer 1

Yould可以嘗試CDI specialization。即：

@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; 
    } 

}
