Я начинаю личный проект с использованием angularjs/пружинные загрузок/данные/спринтерского отдыхомangularjs - springboot - весенние данные/отдых

я столкнулся с проблемой во время объекта сущности, сохраняемого в базе данных

@Entity 
@Table(name="CUSTOMER") 
public class Customer { 

@Id 
@GeneratedValue(strategy = GenerationType.AUTO) 
@Column(name="CUSTOMER_ID") 
private int customerId; 

@Column(name="NAME") 
private String name; 

@Column(name="PHONE_NUMBER") 
private String phoneNumber; 

@Column(name="POSTAL_ADDRESS") 
private String postalAddress; 

@Column(name="CITY") 
private String city; 

@Column(name="COUNTRY") 
private String country; 

@Column(name="EMAIL") 
private String email; 

@OneToMany(mappedBy="customer") 
@OrderBy("name ASC") 
private List<Contact> contacts; 

@ManyToOne 
@JoinColumn(name = "STATUS_ID") 
private RefStatus status;

RefStatus.java

@Entity 
@Table(name="REF_STATUS") 
public class RefStatus { 

@Id 
@Column(name="STATUS_ID") 
private int statusId; 

@Column(name="CODE") 
private String code; 

@Column(name="DESCRIPTION") 
private String description; 

@Column(name="ACTIVE") 
private Boolean active;

CrudRepository

@RepositoryRestResource(collectionResourceRel = "refstatus", path = "refstatus") 
public interface RefStatusRepository extends CrudRepository<RefStatus, Integer> { 
    @Query("SELECT c FROM RefStatus c") 
    List<RefStatus> findAll(); 
}

app.js

$scope.addCustomer = function addCustomer() { 
    if($scope.name==""){ 
     alert("Error"); 
    } 
    else{ 
     $http.post(urlBase + '/customers', { 

     name: $scope.name, 
     status : $scope.statusId 
    }). 
     success(function(data, status, headers) { 
    alert("Customer added"); 
     var newTaskUri = headers()["location"]; 
      }); 
} 
};

HTML страницы

<div ng-controller="taskManagerController"> 
<div id="add-task-panel" class="fadein fadeout addpanel panel"> 
    <div class="panel-body"> 
     <div class="task" > 
      <table class="add-task"> 
       <tr> 
        <td>Customer Name:</td> 
        <td><input type="text" ng-model="name"/></td> 
       </tr> 

       <tr> 
        <td>Status:</td> 
        <td> 


       <select ng-model="statusId" ng-options="status.code for status in items.refstatus"> 
          <option value="">-- Select --</option>      
          </select> 

        </td> 
       </tr> 
       <tr> 
        <td><br/><button ng-click="addCustomer()" class="btn-panel-big">Ajouter client 3</button></td> 
       </tr> 
      </table>         
     </div> 
    </div> 
    </div>

При нажатии на кнопку "addcustomer", это возбуждается исключение:

ли вы, знать, как я могу сохранить объект Клиент, содержащий объект (RefStatus) ?

Я нашел решение.

Я создал контроллер в Java, который вводит все атрибуты из app.js.

 @RequestMapping(value="/create/{name}/{status}",method = RequestMethod.POST,headers="Accept=application/json") 
public Customer create(
     @PathVariable String name, 
     @PathVariable String status){ 
    Customer customer = new Customer(); 
    customer.setName(name); 

    RefStatus refStatus = refStatusRepository.findByCode(status); 
    customer.setStatus(refStatus); 

    return this.customerRepository.save(customer); 
}

Я не знаю, если это лучшее решение, но оно работает отлично :)
