我正在使用端点开发由Google App Engine驱动的android应用程序，并且在我编写的api中，我一直没有明显的原因不断收到堆栈溢出错误。
到目前为止，这是我的端点api类中的2个方法：
@ApiMethod(name = "saveProfile")
public Profile saveProfile(@Named("userId") String userId,
@Named("firstName") String firstName,
@Named("lastName") String lastName,
@Named("birthday") String birthday) {
Profile profile = ofy().load().key(Key.create(Profile.class, userId)).now();
if (profile == null) {
profile = new Profile(userId, firstName, lastName, birthday);
} else {
profile.updateProfile(firstName, lastName, birthday);
}
ofy().save().entity(profile).now();
return profile;
}
@ApiMethod(name = "getSuggestedFriends")
public List<Profile> getSuggestedFriends(@Named("userId") String userId) {
Profile profile = ofy().load().key(Key.create(Profile.class, userId)).now();
if (profile != null) {
/**
* Queries for users with same last name as you (presumably family).
*/
Query<Profile> sameLastName = ofy().load().type(Profile.class).order("birthday");
sameLastName = sameLastName.filter("lastName =", profile.getLastName());
/**
* Gets the friends of your friends.
*/
List<Profile> suggestedFriends = new ArrayList<>(0);
for (Profile friend : profile.getFriends()) {
for (Profile friendOfFriend : friend.getFriends()) {
if (!profile.getFriends().contains(friendOfFriend))
suggestedFriends.add(friendOfFriend);
}
}
/**
* Merge the 2 lists into 1 list of suggested friends.
*/
for (Profile suggestedFriend : sameLastName) {
if (!profile.getFriends().contains(suggestedFriend))
suggestedFriends.add(suggestedFriend);
}
return suggestedFriends;
} else
return null;
}
有人可以提供一些见解和解决方案，以了解为什么会这样吗？

干杯。
在这种情况下会发生这种情况：
public class Entity
{
private List<Entity> children;
}
根据您的情况，您可以尝试@ Serialize'ing孩子。
