private Collection<City> cityCollection;
@XmlTransient
public Collection<City> getCityCollection() {
return cityCollection;
}
REST

@Override
@Produces({"application/xml", "application/json"})
public List<Country> findAll() {
return super.findAll();
}
RESULT
<countries>
<country>
<country>Finland</country>
<countryId>1</countryId>
<lastUpdate>2013-08-30T00:43:35+03:00</lastUpdate>
</country>
<country>
<country>Sweden</country>
<countryId>2</countryId>

</country>
</countries>
问题
为什么即使有字段也没有城市呢?
如何在同一个@GET中获得城市?
甚至可能,我想是这样吗?

答案 0 :(得分:1)
@XmlTransient---> **THIS OFF!**
public Collection<City> getCityCollection() {
return cityCollection;
}
@XmlTransient off我把它移到了:
@XmlTransient
public Country getCountryCountryId() {
return countryCountryId;
}
它正在发挥作用:)
