Dynamic fields in Groovy for a Java class

Is there a way I can create a Java class with a pair of "general" getter/setter methods such as 

public Object get(String name);
public void set(String name, Object object);

and make Groovy translate statements such as

myObject.foo = 'bar'

to

myObject.set("foo", "bar")?

(myObject being an instance of the Java class having the get(String) and set(String, Object) methods)

Have your java class extend groovy.lang.GroovyObjectSupport, which provides implementations of getProperty and setProperty, or impleemnt to the interface groovy.lang.GroovyObject

You have to write two methods in Groovy (assuming you derive your Groovy class from your Java class):

def getProperty(String name) { "This is the property '$name'"   }   
void setProperty(String name, value) { println "You tried to set property '$name' to '$value'"   }
