So lets say we have:
@XmlRootElement(name = "book")
public class Book {
@XmlElement(name = "book_title")
private String title;
public getTitle(){..}
public setTitle(){...}
}
if we run the code we will have
Exception in thread "main"
com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
Class has two properties of the same name "title"
this problem is related to the following location:
at public java.lang.String com.example.jaxb.Book.getTitle()
at com.example.jaxb.Book
this problem is related to the following location:
at private java.lang.String com.example.jaxb.Book.title
at com.example.jaxb.Book
But if we add the annotation: XmlAccessorType
@XmlRootElement(name = "book")
@XmlAccessorType(XmlAccessType.FIELD)
public class Book {
the error will disappear.
When have class which want to marshall and have 10 fields, I prefer to annotate only fields, not one time the setter then the getter. So use @XmlAccessorType and annotate only the fields.
