How do exclude a single variable using ToStringBuilder

I have an object that includes a number of variables but one is a byteArray e.g.

public class DataWithFields {
   private String string1;
   private String string2;
   ....

   private byte[] data    

   public String toString() {
       return ToStringBuilder.reflectionToString(this, ToStringStyle.SHORT_PREFIX_STYLE);
   }

}

For the above code, I want to exclude the data variable from the toString without having to explicitly define each value. How do I do this?

Simplier solution :

@Override
public String toString() {
    return ReflectionToStringBuilder.toStringExclude(this, "data");
}

If DefaultToStringStyle is doesn't fit your application needs, make sure to call

ReflectionToStringBuilder.setDefaultStyle(style);

at application start.

If you have more fields to exclude, just add them after or before "data"

@Override
public String toString() {
    return ReflectionToStringBuilder.toStringExclude(this, "fieldX","data", "fieldY");
}
