Over Christmas, I realeased a new open source project: jObjectFormatter, a simple toString() generator for java. Using it is really easy: Just override your toString methods with:

@Override
public void toString() {
    return ObjectFormatter.format(this);
}

Ok, there is a little bit more to it: jObjectFormatter is fully configurable. You can define how your objects should be formatted and which properties should be part of the output. You can find more information in the official documentation on GitHub:

• Project Page

I hope you have fun with it, and I would really appreciate your feedback.
