--------------------------------------
Have a look here:

I think it would be easy to port the code (after some review) to commons lang.

> annotations based builders
> --------------------------
>
> Key: LANG-395
> URL: https://issues.apache.org/jira/browse/LANG-395
> Project: Commons Lang
> Issue Type: New Feature
> Reporter: Jörg Gottschling
> Fix For: 3.0
>
>
> What about enabling the builders (ToStringBuilder, EqualsBuilder, etc.) that
> use reflection to use annotations to find the field to include?
> Something like:
> ToStringBuilder.annotationsBasedToString(Object object, Class<Annotation>
> class, Class<?> reflectUpToClass)
> One could use the JPA-Annotation @ID for example, espescially for Equals- and
> HashCodeBuilder. There should also be some default annotation comming with
> LangTwo.
> Usage:
> public class User
> {
> @StringRepresentation
> @EqualsAndHashCode
> private String name
> @StringRepresentation
> private String email;
> private String password;
> // ...
> @Override
> public String toString()
> {
> return annotationsBasedToString(this);
> }
> @Override
> public boolean equals(Object other)
> {
> return annotationsBasedEquals(this, other);
> }
> @Override
> public int hashCode()
> {
> return annotationsBasedHashCode(this);
> }
> }
