Не удается создать больше, чем метод в классе конечных точек в облачных конечных точках Google

Question

Я пытался создать новый метод в моем сгенерированном классе Endpoint, и я нашел это странное поведение: я могу добавить метод к сгенерированному классу, но я не может добавить два из них, независимо от того, какой из двух я добавляю. Это код моего сгенерированного класса, где я добавил код для двух добавленных методов:

Вы знаете, как помочь мне? Я что-то упускаю?

Answer 1

Ваши методы имеют то же описание api (path="utenteendpoint/{param}"). Дайте одну из них другой путь:

@ApiMethod(path="utenteendpoint/tag/{tag}/") 
public List<Bill> getUserBillsByTag(@Named("tag") String tag) { ... } 

@ApiMethod(path="utenteendpoint/user/{id}/") 
public List<Bill> getUserBills(@Named("id") Long id) { ... }
