Example of using a BeanInfo class for custom getter/setter names for Groovy properties.

SomeBean.groovy

class SomeBean {
    private String _memo

    String foo() { _memo }
    void foo(String v) { _memo = v }

    public static void main(String[] args) {
        SomeBean bean = new SomeBean();
        bean.foo = 'bar'
        println bean.foo
    }
}

SomeBeanBeanInfo.java

import java.beans.IntrospectionException;
import java.beans.PropertyDescriptor;
import java.beans.SimpleBeanInfo;

public class SomeBeanBeanInfo extends SimpleBeanInfo {
    @Override
    public PropertyDescriptor[] getPropertyDescriptors() {
        try {
            return new PropertyDescriptor[]{
                    new PropertyDescriptor("foo"
                        , SomeBean.class.getMethod("foo")
                        , SomeBean.class.getMethod("foo", String.class))};
        } catch (IntrospectionException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
        return null;
    }
}
