看来你可能已经注释了getPeople和setPeople方法。 JAXB（和其他Java EE技术）只需要您注释一个。

It appears that you may have annotated both the getPeople and setPeople methods. JAXB (and other Java EE technologies) only require you annotate one.

public class Community {

    private List<Person> people;

    @XmlElementRef
    public List<Person> getPeople() {
        return people;
    }

    public void setPeople(List<Person> people) {
        this.people = people;
    } 

}
