hibernate 在迭代器上使用next()时，即使数据存在，也会在使用hql查询提取数据后出现异常

下面是我正在使用的Hql查询。我正在打印customerRequestDetails，数据是存在的。但是当我在该集合对象上使用迭代器并调用next（）时，我得到了异常。但是如果我从下面的查询中删除group by，则不会出现异常，但会出现没有group by的重复数据。

使用分组依据进行查询：

from
    CustomerTravelRequest customerTravelRequest
    left join fetch customerTravelRequest.customer  customer
    left join fetch customer.rewardProgram rewardProgram
    join fetch customerTravelRequest.customerRequestDetails customerRequestDetails  
where
    (customerTravelRequest.requestStatus LIKE 'OPEN' OR customerTravelRequest.requestStatus LIKE 'BLOCK' OR customerTravelRequest.requestStatus LIKE 'FOLLOWUP') AND
    customer.id = ? AND
    customerTravelRequest.companyId=:companyId
    group by customerTravelRequest.id
    order by customerRequestDetails.id

不使用分组依据进行查询：

from
    CustomerTravelRequest customerTravelRequest
    left join fetch customerTravelRequest.customer  customer
    left join fetch customer.rewardProgram rewardProgram
    left join fetch customerTravelRequest.customerRequestDetails customerRequestDetails
where
    (customerTravelRequest.requestStatus LIKE 'OPEN' OR customerTravelRequest.requestStatus LIKE 'BLOCK' OR customerTravelRequest.requestStatus LIKE 'FOLLOWUP') AND
    customer.id = ? AND
    customerTravelRequest.companyId=:companyId

实体类如下：

@Entity
@DynamicInsert
@DynamicUpdate
@Table(name = "CUSTOMER_REQUEST_INFO")
@Audited
public class CustomerTravelRequest extends CompanyIdDto {

private Set<CustomerRequestDetails> customerRequestDetails;

@OneToMany(mappedBy = "customerTravelRequest", cascade = CascadeType.ALL, fetch = FetchType.LAZY, orphanRemoval = true)
@OptimisticLock(excluded = true)
@OrderBy
public Set<CustomerRequestDetails> getCustomerRequestDetails() {
    return customerRequestDetails;
}

/**
 * @param customerRequestDetails the customerRequestDetails to set
 */
public void setCustomerRequestDetails(Set<CustomerRequestDetails> customerRequestDetails) {
    this.customerRequestDetails = customerRequestDetails;
}
}

@Entity
@DynamicInsert
@DynamicUpdate
@Table(name = "CUSTOMER_REQUEST_DETAILS")
@Audited
public class CustomerRequestDetails extends BaseDto {

private CustomerTravelRequest customerTravelRequest;

@ManyToOne
@JoinColumn(name = "CUSTOMER_REQUEST_ID")
@OptimisticLock(excluded = true)
public CustomerTravelRequest getCustomerTravelRequest() {
    return customerTravelRequest;
}

/**
 * @param customerTravelRequest the customerTravelRequest to set
 */
public void setCustomerTravelRequest(CustomerTravelRequest customerTravelRequest) {
    this.customerTravelRequest = customerTravelRequest;
}
}

我遇到的异常：

以下是配置

  • Java 1.8版
  • 雄猫7
  • 我的SQL版本5.1.22
  • 公用-dbcp 1.4
  • Spring应用程序版本：4.1.4
  • 休眠版本：4.3.8.Final

运行测试用例时不会出现此异常，仅当应用程序在服务器上运行时才会出现此异常

以下列方式访问requestdetails

Iterator<CustomerRequestDetails> customerRequestDetailsIterator = customerTravelRequest.getCustomerRequestDetails().iterator();
    Iterator<CustomerRequestDetails> dupCustomerRequestDetailsIterator = duplicateCustomerTravelRequest.getCustomerRequestDetails().iterator();
    CustomerRequestDetails customerRequestDetails = customerRequestDetailsIterator.next();
    CustomerRequestDetails dupCustomerRequestDetails = dupCustomerRequestDetailsIterator.next();

您必须向我们展示CustomerEventServiceImpl的代码以进一步帮助您，但我猜您在迭代LinkedHashMap或类似操作时正在修改它。另外，请注意，Hibernate 4.3现在已经非常旧了，因此即使Hibernate中存在bug，也没有人能够在此时帮助您。是时候进行更新了;）
