Given the following class public class Foo { public int FooId { get; set; } public string FooName { get; set; } public override bool Equals(object obj) { Foo fooItem = obj as Foo; return fooItem.FooId == this.FooId; } public override int GetHashCode() { // Which is preferred? return base.GetHashCode(); //return this.FooId.GetHashCode(); } }

Eclipse 3.5 has a very nice feature to generate Java hashCode() functions. It would generate for example (slightly shortened:)

I'm curious to know, what people here think about using org.apache.commons.lang.builder EqualsBuilder/HashCodeBuilder for implementing the equals/hashcode? Would it be a better practice than writing your own? Does it play well with Hibernate? What's your opinion?
