JSR 303的驗證覆蓋

我怎麼能去在下列情況下重寫驗證上的電子郵件爲AuthorizedUser：JSR 303的驗證覆蓋

public class Account { 
    @Length(min = 1, max = 100, 
      message = "'Email' must be between 1 and 100 characters in length.") 
    @NotNull(message = "'Email' must not be empty.") 
    protected String email; 

    @Length(min = 1, max = 50, 
      message = "'Name' must be between 1 and 50 characters in length.") 
    private String name; 
} 

public class AuthorizedUser extends Account { 
    @Length(min = 1, max = 40, 
      message = "'Field' must be between 1 and 50 characters in length.") 
    private String field; 
}

我知道由二傳手覆蓋的電子郵件地址，我可以「砍」的解決方案對通過執行AuthorizedUser如下：

@Override 
public void setEmail(String email) { 
    this.email = email; 
    super.setEmail(" "); 
}

我就覺得骯髒...這是可能的，而無需編寫自定義驗證程序被重寫？

我試着將@Valid移動到超類的setter中，並將它放在覆蓋的字段中，但仍然收到超類中關於它爲空的消息。有沒有更懶惰的方法來做到這一點？

到目前爲止，我結束了編寫自定義驗證，在我簡單的例子下面的情況下工作，但在更復雜的模型中，我認爲需要製作更多的課程是沒有意義的。 – Scott

由於約束是通過繼承聚集，最好的解決辦法可能是你的繼承層次改變這樣的事情：

public class BasicAccount { 
    protected String email; 

    @Length(min = 1, max = 50, 
      message = "'Name' must be between 1 and 50 characters in length.") 
    private String name; 
} 

public class EmailValidatedAccount extends BasicAccount { 
    @Length(min = 1, max = 100, 
      message = "'Email' must be between 1 and 100 characters in length.") 
    @NotNull(message = "'Email' must not be empty.") 
    @Override 
    public String getEmail() { 
    return email; 
    } 
} 

public class AuthorizedUser extends BasicAccount { 
    @Length(min = 1, max = 40, 
      message = "'Field' must be between 1 and 50 characters in length.") 
    private String field; 
}
