See org.apache.commons.lang.builder.ToStringBuilder and org.apache.commons.lang.builder.EqualsBuilder and related classes in Apache Commons lang.

And as far as I can tell, the equals() method isn't valid as its not necessarily transitive or symmetric, which means it might break any data structure that holds an object implementing it. Not to mention the possibility of an infinite recursion occurring in there...
