@ToString need feature to mask output

[vinothm]

Hi Team,

I have constant requirement in our projects print masked data part logs, this help debug quickly and does allow user to mask output to certain characters.

Example:

public class ReportRequest {

    @ToString.masked(3) public String userId;

}

If called with value as vinothm, should print vin****.

Can this be added as feature to the ToString annotation?

Thanks,

VinothM

I'm afraid, that's much too specialized for any general purpose tool.

But you can write

@ToString.Include

private userId() {

    return userId.length() <= 3 ? userId

    : userId.substring(0, 3) + com.google.common.base.Strings.repeat("*", userId.length() - 3);

}

and Lombok picks it instead of the field.
