WebServices with CXF - My DTO's

For your DTO's youmust apply the same rule like with every Java Bean (getter's & setter's, toString, hashCode, equals & Serialization)

My first step is creating a base DTO with all common fields and methods, then it's just extending from that class. I'll just put 2 examples, Ok?

package mx.com.mylibrary.core.business.dto; import java.io.Serializable; import java.util.Date; public abstract class BaseDTO implements Serializable { private static final long serialVersionUID = -2375424405198208312L; private Date createDate; public Date getCreateDate() { return createDate; } public void setCreateDate(Date createDate) { this.createDate = createDate; } @Override public abstract int hashCode(); @Override public abstract boolean equals(Object obj); } package mx.com.mylibrary.core.business.dto; import java.io.Serializable; import java.util.List; /** * * Data Transfer Object * * @author Juan Carlos Cruz * @since May 23 2010 */ public class AuthorDTO extends BaseDTO implements Serializable { private static final long serialVersionUID = -5573197656310571940L; private Integer authorId; private String name; private String email; private List<BookDTO> listBooks; //getter's and setter's } package mx.com.mylibrary.core.business.dto; import java.io.Serializable; import java.util.List; /** * * Data Transfer Object * * @author Juan Carlos Cruz * @since May 23 2010 */ @XmlType(name="Book") public class BookDTO extends BaseDTO implements Serializable { private static final long serialVersionUID = 3254611377962442345L; private Integer bookId; private String title; private EditorDTO editorDTO = new EditorDTO(); private List<AuthorDTO> listAutors; //getter's and setter's }

Later we'll have to retake this objects, because we'll have add some extra lines (anotations) just to make them compatible with our WebServices framework, it will be fun.
