我正在使用端点开发一个谷歌应用引擎驱动的Android应用程序，在我正在编写的api中，我不断出现堆栈溢出错误。
到目前为止，我的端点api类中有两种方法：
@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，说明为什么会这样吗？
