angularjs上的ERR_INCOMPLETE_CHUNKED_ENCODING - 休息服務使用高級REST客戶端返回無限的json文件，但郵遞員錯誤

Question

我有一個非常奇怪的問題。 在angular（使用離子v1構建的應用程序）中，我調用了一些用java構建的REST調用，但是出了點問題，chrome告訴我這個錯誤：

有趣的代碼就是這個，角度為js的REST服務：

 bankaccountsbyuser: function(_getbauser, _error){ var currentToken = _GetToken(); if(currentToken!=null){ var Headers = { token: currentToken.tokenUser, }; } _timerTokenControl(currentToken, _error); if (setupTime == null) { console.log("token scaduto"); //modificare //$window.location.href="login.html"; } if (currentToken !== null) { $http({ method : 'GET', headers: Headers, url : REST_URL+'bankaccount' }).then(function successCallback(response) { console.log(response) _getbauser(response) }, function errorCallback(response) { console.log(response.statusText); }); } else { var alertPopup = $ionicPopup.alert({ title: 'Accesso negato!', template: 'Devi essere un utente registrato, non sei loggato!' }); console.log("NON SEI LOGGATO!!!"); } }, 

調試：

你怎么看，get REST服務返回一個錯誤，讓我們看看這個用java構建的REST服務：

 package it.jack.fdd.services; import java.util.List; import javax.ws.rs.DELETE; import javax.ws.rs.GET; import javax.ws.rs.HeaderParam; import javax.ws.rs.POST; import javax.ws.rs.PUT; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; import it.jack.fdd.dao.FactoryDao; import it.jack.fdd.dao.impl.BankAccountDaoImpl; import it.jack.fdd.dao.interfaces.BankAccountDao; import it.jack.fdd.domain.BankAccount; import it.jack.fdd.domain.User; import it.jack.fdd.dto.TokenUserDto; import it.jack.fdd.dto.UserDto; import it.jack.fdd.util.ConverterDTO; @Path("/bankaccount") public class BankAccountServices { @GET @Produces(MediaType.APPLICATION_JSON) public List<BankAccount> getBankAccountOfUser() { BankAccountDao baDao = new BankAccountDaoImpl(); List<BankAccount> balist = baDao.getBAByUserId(1); return balist; } 

我試圖在方法中傳遞數字“1”，只是為了簡化。 該方法實現如下：

 package it.jack.fdd.dao.impl; import java.util.List; import org.hibernate.HibernateException; import org.hibernate.Query; import org.hibernate.Session; import org.hibernate.Transaction; import it.jack.fdd.dao.interfaces.BankAccountDao; import it.jack.fdd.domain.BankAccount; import it.jack.fdd.domain.Staff; import it.jack.fdd.domain.User; import it.jack.fdd.util.HibernateUtilLezione; public class BankAccountDaoImpl extends BaseDaoImpl<BankAccount> implements BankAccountDao{ public List<BankAccount> getBAByUserId(int id) { try{ Session session = HibernateUtilLezione.openSession(); Transaction tx = session.beginTransaction(); @SuppressWarnings("unchecked") List<BankAccount> accounts = session.createQuery("from BankAccount b " + "where b.user= "+id).list(); tx.commit(); session.close(); return accounts; } catch(HibernateException e){ e.printStackTrace(); return null; } } } 

正如你所看到的，該方法要求一個id，我只是將id 1用於檢查，因為在數據庫中有一個帶有該id的字段。 嘗試在java中，它返回一個列表

[it.jack.fdd.domain.BankAccount@4f8d86e4]

我還檢查了列表的維度為1（因此，只有一條記錄，就像在數據庫中一樣，只有1條記錄具有該iduser）

因此，嘗試使用郵遞員打開此REST調用，結果如下：

奇怪的是，郵遞員向我展示了另一個REST調用的相同結果，它之前有效。 但是對於這最后一次REST調用不是問題，因為奇怪的是它適用於我的應用程序，它不僅僅適用於郵遞員。 因此，嘗試使用高級REST客戶端我有一個奇怪的不同結果：

一個奇怪的，非常大的列表，每次重復相同的字段！ 這就像一個循環！ 怎么了？ 我怎么解決？

解決了。 問題出在java的域類中：當域類具有一對多關系時，必須將標記@JsonIgnore放在json文件中以避免這些重復記錄

實體類：
